Accounting Policies [Abstract] |  |
Nature of Operations | Nature of Operations Duos Technologies Group, Inc. (the “Company”), through its operating subsidiaries, Duos Technologies, Inc. (“Duos”) and TrueVue360, Inc. (“TrueVue360”) (collectively the “Company”), is a company that specializes in machine vision and artificial intelligence to analyze fast moving objects such as trains, trucks, automobiles, and aircraft. This technology can help improve safety, maintenance, and operating metrics. The Company is the inventor of the Railcar Inspection Portal (RIP) and is currently the rail industry leader for machine vision/camera wayside detection systems that include the use of Artificial Intelligence at speeds up to 125 mph. The RIP inspects a train at full speed from the top, sides, and bottom looking at FRA/AAR mandated safety inspection points. The system also detects illegal riders that assists law enforcement agencies. Each rail car is scanned with machine vision cameras and other sensors from the top, sides, and bottom and images are produced within seconds of passing that can be used by the customer to help prevent derailments, improve maintenance operations, and assist with security. The Company self-performs all aspects of hardware, software, IT, and Artificial Intelligence development and engineering and holds several patents and maintains significant intellectual property. The Company also has a proprietary portfolio of over 40 Artificial Intelligence “Use Cases” that automatically flag defects. The Company has deployed this system with several Class 1 and passenger customers and anticipates an increased demand in the future from rail operators, car owners, shippers, and law enforcement agencies. The Company has also developed the Automated Logistics Information System (ALIS) which automates gatehouse operations where trucks enter and exit large logistics and intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects with backend logistics databases and processes to streamline operations and significantly improve operations and security and, importantly, dramatically improves throughput on each lane on which the technology is deployed. The Company expects to deploy an upgraded Truck Inspection Portal (TIP) which uses the same technology and lessons learned from the ALIS and RIP systems. The Company’s strategy is to expand our existing customer base in the Class 1, short line, and passenger space in North America; expand our subscription offering to car owners and shippers; and expand operations to meet the demand from international customers. The Company has prepared to respond and scale if necessary to react to increased demand from potential regulations that may be imposed around wayside detection technology. In the future the Company may put more emphasis on the trucking and intermodal sector with an updated Truck Inspection Portal solution. The Company continues to focus on operational and technical excellence, customer satisfaction, and maintaining a highly skilled and performance-based work force. | Nature of Operations Duos Technologies Group, Inc. (the “Company”), through its operating subsidiaries, Duos Technologies, Inc. (“Duos”) and TrueVue360, Inc. (“TrueVue360”) (collectively the “Company”), develops and deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries. The Company has developed the Railcar Inspection Portal (RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the undercarriage. These images are then processed through various methods of artificial intelligence (“AI”) algorithms to identify specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal. This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future. Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which also directly benefits the Class 1 railroads through increasing their velocity. The Company has also developed the Automated Logistics Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly dramatically improves the vehicle throughput on each lane on which the technology is deployed. The Company has built a portfolio of IP and patented solutions that creates “actionable intelligence” using two core native platforms called Centraco® and Praesidium™. All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various image capture devices and some sensors for input into the Centraco software. The Company also developed a proprietary Artificial Intelligence (AI) software platform, Truevue360™ with the objective of focusing the Company’s advanced intelligent technologies in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions. Through September 30, 2021, the Company also provided professional and consulting services for large data centers and had developed a system for the automation of asset information marketed as DcVue™. The Company had deployed its DcVue software at one beta site. This software was used by Duos’ consulting auditing teams. DcVue was based upon the Company’s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed software product. The Company ceased offering this product in 2021. The Company’s strategy is to deliver operational and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics and U.S. Government Sectors, offer both one-time equipment sales and capital lease pricing models, and longer-term offer subscription pricing, to customers that increases recurring revenue, grows backlog and improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based work force where employees enjoy their work and are incentivized to excel and remain with the Company.

Principles of Consolidation | Principles of Consolidation The unaudited consolidated financial statements include Duos Technologies Group, Inc. and its wholly owned subsidiaries, Duos Technologies, Inc. and TrueVue360 Inc. All inter-company transactions and balances are eliminated in consolidation. | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. All inter-company transactions and balances are eliminated in consolidation.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts receivable and notes receivable, valuation of common stock warrants received in exchange for an asset sale, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress towards contract completion, valuation of inventory, estimates of the valuation of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

Concentrations | Concentrations Cash Concentrations Cash is maintained at financial institutions and at times, balances may exceed federally insured limits. We have not experienced any losses related to these balances. As of September 30, 2023, the balance in one financial institution exceeded federally insured limits by approximately $2,768,466. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s consolidated financial condition, results of operation and cash flows. Significant Customers and Concentration of Credit Risk The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: For the nine months ended September 30, 2023, two customers accounted for 55% and 29% of revenues. For the nine months ended September 30, 2022, four customers accounted for 25%, 21%, 19% and 19% of revenues. In all cases, there are no minimum contract values stated. Each contract covers an agreement to deliver a Railcar Inspection Portal which, once accepted, must be paid in full, with 30% or more being due and payable prior to delivery. The balances of the contracts are for service and maintenance which is paid annually in advance with revenues recorded ratably over the contract period. At September 30, 2023, three customers accounted for 52%, 25%, and 14% of accounts receivable. At December 31, 2022, four customers accounted for 34%, 31%, 19% and 10% of accounts receivable. Much of the credit risk is mitigated since all the customers listed here are Class 1 railroads with a history of timely payments to us. Geographic Concentration For the nine months ended September 30, 2023, approximately 37% of revenue was generated from three customers outside of the United States. For the nine months ended September 30, 2022, approximately 54% of revenue was generated from four customers outside of the United States. These customers are Canadian and Mexican, and, for the nine months ended September 30, 2023, two of the three are Class 1 railroads operating in the United States. Significant Vendors and Concentration of Credit Risk In some instances, the Company relies on a limited pool of vendors for key components related to the manufacturing of its subsystems. These vendors are primarily focused on camera, server and lighting technologies integral to the Company’s solution. Where possible, the Company seeks multiple vendors for key components to mitigate vendor concentration risk. | Concentrations Cash Concentrations Cash is maintained at financial institutions and at times, balances may exceed federally insured limits. We have not experienced any losses related to these balances. As of December 31, 2022, the Company had balances in a financial institution which combined exceeded federally insured limits by approximately $688,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s consolidated financial condition, results of operation and cash flows. Significant Customers and Concentration of Credit Risk The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: For the year ended December 31, 2022, four customers accounted for 42%,18%, 14% and 14% of revenues. For the year ended December 31, 2021, a single customer accounted for 83% of revenues. In all cases, there are no minimum contract values stated. Each contract covers an agreement to deliver a rail inspection portal which, once accepted, must be paid in full, with 30% or more being due and payable prior to delivery. The balances of the contracts are for service and maintenance which is paid annually in advance with revenues recorded ratably over the contract period.

Much of the credit risk is mitigated since all of the customers listed here are Class 1 railroads with a history of timely payments to us. Geographic Concentration Approximately 41% and 86% of revenue in 2022 and 2021, respectively, is generated from customers outside of the United States. Significant Vendors and Concentration In some instances, the Company relies on a limited pool of vendors for key components related to the manufacturing of its subsystems. These vendors are primarily focused on camera, server and lighting technologies integral to the Company’s solution where possible, the Company seeks multiple vendors for key components to mitigate vendor concentration risk.
Fair Value of Financial Instruments and Fair Value Measurements | Fair Value of Financial Instruments and Fair Value Measurements The Company follows Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below:
Level 1: | Observable inputs such as quoted market prices in active markets for identical assets or liabilities.
Level 2: | Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: | Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions that the market participants would use in the valuation of the asset or liability based on the best available information.
The Company analyzes all financial instruments with features of both liabilities and equity under the Financial Accounting Standard Board’s (“FASB”) accounting standard for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The estimated fair value of certain financial instruments, including accounts receivable, prepaid expenses, accounts payable, accrued expenses and notes payable are carried at historical cost basis, which approximates their fair values because of the short-term nature of these instruments. | Fair Value of Financial Instruments and Fair Value Measurements The Company follows Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis.

Accounts Receivable | Accounts Receivable On January 1, 2023, the Company adopted ASC 326, “Financial Instruments - Credit Losses”. In accordance with ASC 326, an allowance is maintained for estimated forward-looking losses resulting from the possible inability of customers to make required payments (current expected losses). The amount of the allowance is determined principally on the basis of past collection experience and known financial factors regarding specific customers. Accounts receivable are stated at estimated net realizable value. Accounts receivable are comprised of balances due from customers net of estimated allowances for uncollectible accounts. In determining the collections on the account, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances. The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based on how recently payments have been received from customers. | Accounts Receivable Accounts receivable are stated at estimated net realizable value.

Past due status is based on how recently payments have been received from customers.
Inventory | Inventory Inventory consists primarily of spare parts and consumables and long lead time components to be used in the production of our technology systems or in connection with maintenance agreements with customers. Any inventory deemed to be obsolete is written off. Inventory is stated at the lower of cost or net realizable value. Inventory cost is primarily determined using the weighted average cost method. | Inventory Inventory consists primarily of spare parts, consumables and long-lead components to be used in the production of our technology systems or in connection with maintenance agreements with customers.

Inventory cost is primarily determined using the weighted average cost method.
Property and Equipment |  | Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation is provided by the straight-line method over the estimated economic life of the property and equipment (three 3 to five 5 years). When assets are sold or retired, their costs and accumulated depreciation are eliminated from the accounts and any gain or loss resulting from their disposal is included in the statement of operations. Leasehold improvements are expensed over the shorter of the term of our lease or their useful lives.
Software Development Costs | Software Development Costs Software development costs incurred prior to establishing technological feasibility are charged to operations and included in research and development costs. The technological feasibility of a software product is established when the Company has completed all planning, designing, coding, and testing activities that are necessary to establish that the product meets its design specifications, including functionality, features, and technical performance requirements. Software development costs incurred after establishing technological feasibility for software sold as a perpetual license, as defined within ASC 985-20 (Software – Costs of Software to be Sold, Leased, or Marketed), are capitalized and amortized on a product-by-product basis when the product is available for general release to customers. | Software Development Costs Software development costs incurred prior to establishing technological feasibility are charged to operations and included in research and development costs.

Patents and Trademarks |  | Patents and Trademarks Patents and trademarks which are stated at amortized cost, relate to the development of video surveillance security system technology and are being amortized over 17 years.
Long-Lived Assets |  | Long-Lived Assets The Company evaluates the recoverability of its property, equipment, and other long-lived assets in accordance with FASB ASC 360-10-35-15 “Impairment or Disposal of Long-Lived Assets”, which requires recognition of impairment of long-lived assets in the event the net book values of such assets exceed the estimated future undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
Product Warranties |  | Product Warranties The Company has a 90-day warranty period for materials and labor after final acceptance of a project. If any parts are defective they are replaced under our vendor warranty which is usually 12 to 36 months. Final acceptance terms vary by customer. Some customers have a cure period for any material deviation and if the Company fails or is unable to correct any deviations, a full refund of all payments made by the customer will be arranged by the Company. As of December 31, 2022 and 2021, the warranty costs have been de-minimis, therefore no accrual of warranty liability has been made.
Loan Costs |  | Loan Costs Loan costs paid to lenders, or third parties are recorded as debt discounts to the related loans and amortized to interest expense over the loan term.
Sales Returns |  | Sales Returns Our systems are sold as integrated systems and there are no sales returns allowed.
Revenue Recognition | Revenue Recognition The Company follows Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), that affects the timing of when certain types of revenues will be recognized. The basic principles in ASC 606 include the following: a contract with a customer creates distinct contract assets and performance obligations, satisfaction of a performance obligation creates revenue, and a performance obligation is satisfied upon transfer of control to a good or service to a customer. Revenue is recognized by evaluating our revenue contracts with customers based on the five-step model under ASC 606:
| 1. | Identify the contract with the customer;
| 2. | Identify the performance obligations in the contract;
| 3. | Determine the transaction price;
| 4. | Allocate the transaction price to separate performance obligations; and
| 5. | Recognize revenue when (or as) each performance obligation is satisfied.
The Company generates revenue from four sources: (1) Technology Systems (2) AI Technologies (3) Technical Support (4) Consulting Services Technology Systems For revenues related to technology systems, the Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue to recognize. Accordingly, the Company bases its revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured and revenue is recognized accordingly. In addition, the Company has adopted ASC 606-10-55-21 such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192. Under this method, contract revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in “contract assets”. Any billings of customers more than recognized revenues are recorded as a liability in “contract liabilities”. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined to be both probable and reasonably estimable. AI Technologies The Company has revenue from applications that incorporate artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon acceptance, as well as an annual application maintenance fee, which is recognized as revenue ratably over the contracted maintenance term. Technical Support Technical support services are provided on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided outside of a maintenance contract are on an “as-requested” basis, and revenue is recognized over time as the services are provided. Revenue for maintenance and technical support provided on an extended-term basis is recognized over time ratably over the term of the contract. Consulting Services The Company’s consulting services business generates revenues under contracts with customers from four sources: (1) Professional Services (consulting and auditing); (2) Software licensing with optional hardware sales; (3) Customer service training and (4) Maintenance/support. (1) Revenues for professional services, which are of short-term duration, are recognized when services are completed; (2) For all periods reflected in this report, software license sales have been one-time sales of a perpetual license to use our software product and the customer also has the option to purchase third-party manufactured handheld devices from us if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware, as applicable, to the customer; (3) Training sales are one-time upfront short-term training sessions and are recognized after the service has been performed; and (4) Maintenance/support is an optional product sold to our software license customers under one-year contracts. Accordingly, maintenance payments received upfront are deferred and recognized over the contract term. | Revenue Recognition The Company follows Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), that affects the timing of when certain types of revenues will be recognized.

The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon acceptance, as well as an annual application maintenance fee, which is recognized as revenue ratably over the contracted maintenance term. Technical Support Technical support services are provided on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided outside of a maintenance contract are on an “as-requested” basis, and revenue is recognized over time as the services are provided. Revenue for maintenance and technical support provided on an extended-term basis is recognized over time ratably over the term of the contract. Consulting Services The Company’s consulting services business generates revenues under contracts with customers from four sources: (1) Professional Services (consulting and auditing); (2) Software licensing with optional hardware sales; (3) Customer service training and (4) Maintenance support. (1) Revenues for professional services, which are of short-term duration, are recognized when services are completed; (2) For all periods reflected in this report, software license sales have been one-time sales of a perpetual license to use our software product and the customer also has the option to purchase third-party manufactured handheld devices from us if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware, as applicable, to the customer; (3) Training sales are one-time upfront short-term training sessions and are recognized after the service has been performed; and (4) Maintenance/support is an optional product sold to our software license customers under one-year contracts. Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.
Multiple Performance Obligations and Allocation of Transaction Price | Multiple Performance Obligations and Allocation of Transaction Price Arrangements with customers may involve multiple performance obligations including project revenue and maintenance services in our Technology Systems business. Maintenance will occur after the project is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple performance obligations may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for a multiple performance obligations arrangement is as follows: Each performance obligation is accounted for separately when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable. For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated, the revenue for each performance obligation is recognized using the applicable criteria under GAAP as discussed above for performance obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company customers qualify as separate units of account for revenue recognition purposes. | Multiple Performance Obligations and Allocation of Transaction Price Arrangements with customers may involve multiple performance obligations including project revenue and maintenance services in our Technology Systems business.

Advertising |  | Advertising The Company expenses the cost of advertising. During the years ended December 31, 2022 and 2021, there were no advertising costs.
Stock-Based Compensation | Stock-Based Compensation The Company accounts for employee stock-based compensation in accordance with ASC 718-10, “Share-Based Payment,” which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options, restricted stock units, and employee stock purchases based on estimated fair values. The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The Company’s determination of fair value using an option-pricing model is affected by the stock price as well as assumptions regarding a number of highly subjective variables. The Company estimates volatility based upon the historical stock price of the Company and estimates the expected term for stock options using the simplified method for employees and directors and the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury securities with similar maturities. | Stock Based Compensation The Company accounts for employee and non-employee stock-based compensation in accordance with ASC 718-10, “Share-Based Payment,” which requires the measurement and recognition of compensation expense for all share-based payment awards made including stock options, restricted stock units, and stock purchases based on estimated fair values.

Income Taxes |  | Income Taxes The Company accounts for income taxes in accordance with the Financial Accounting Standards Board FASB Accounting Standards Codification (“ASC”) 740, Income Taxes, which requires the recognition of deferred income taxes for differences between the basis of assets and liabilities for financial statement and income tax purposes. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company evaluates all significant tax positions as required by ASC 740. As of December 31, 2022, the Company does not believe that it has taken any positions that would require the recording of any additional tax liability, nor does it believe that there are any unrealized tax benefits that would either increase or decrease within the next year. Any penalties and interest assessed by income taxing authorities are included in operating expenses. The federal and state income tax returns of the Company are subject to examination by the IRS and state taxing authorities, generally for three years after they were filed. Tax years 2019, 2020 and 2021 remain open for potential audit.
Earnings (Loss) Per Share | Earnings (Loss) Per Share Basic earnings per share (EPS) are computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise or conversion of stock options, stock warrants, convertible debt instruments, convertible preferred stock or other common stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. At September 30, 2023, there were (i) an aggregate of 80,091 outstanding warrants to purchase shares of common stock, (ii) employee stock options to purchase an aggregate of 1,217,775 shares of common stock, (iii) 433,000 common shares issuable upon conversion of Series D Convertible Preferred Stock, (iv) 1,333,334 common shares issuable upon conversion of Series E Convertible Preferred Stock, and (v) 806,452 common shares issuable upon conversion of Series F Convertible Preferred Stock, all of which were excluded from the computation of diluted net earnings per share because their inclusion would have been anti-dilutive. At September 30, 2022, there were (i) an aggregate of 1,376,466 outstanding warrants to purchase shares of common stock, (ii) employee stock options to purchase an aggregate of 926,266 shares of common stock and (iii) 333,000 common shares issuable upon conversion of Series D Convertible Preferred Stock, all of which were excluded from the computation of diluted net earnings per share because their inclusion would have been anti-dilutive. | Earnings (Loss) Per Share Basic earnings per share (EPS) are computed by dividing net loss applicable to common stock by the weighted average number of common shares outstanding.

Leases | Leases The Company follows ASC 842 “Leases”. This guidance requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities for most operating leases. In addition, this guidance requires that lessors separate lease and non-lease components in a contract in accordance with the revenue guidance in ASC 606. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single lease component. At the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company’s assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether we have the right to direct the use of the asset. Operating ROU assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date to determine the present value of future payments. The lease term includes all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included in general and administration expenses in the consolidated statements of operations. | Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842). The updated guidance requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and non-lease components in a contract in accordance with the new revenue guidance in ASC 606. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018. The Company adopted this guidance effective January 1, 2019, using the modified retrospective method, whereby a cumulative effect adjustment was made as of the date of initial application. The Company also applied the package of practical expedients to leases that commenced before the effective date whereby the Company elected to not reassess the following: (i) whether any expired or existing contracts contain leases and (ii) initial direct costs for any existing leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single lease component. The adoption of ASU 2016-02 did not materially affect our consolidated statement of operations or our consolidated statement of cash flows. For contracts entered into on or after the effective date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company’s assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset. Operating ROU assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date to determine the present value of future payments. The lease term includes all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included in general and administrative expenses in the consolidated statements of operations.
Recent Accounting Pronouncements | Recent Accounting Pronouncements From time to time, the FASB or other standards setting bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards Update (“ASU”). In August 2020, the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. The Company early adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a material effect on our audited consolidated financial statements. In May 2021, the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2021. The pronouncement is applied prospectively to all modifications that occur after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a material effect on our audited consolidated financial statements. Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements. | Recent Accounting Pronouncements From time to time, the FASB or other standards setting bodies will issue new accounting pronouncements.

This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023.

During 2022, the Company did not issue any equity classified written call options or warrant during the year and does not foresee any issuances in the near future. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which significantly changes how entities will measure credit losses for most financial assets, including accounts receivable. ASU No. 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. On November 15, 2019, the FASB delayed the effective date of Topic 326 for certain small public companies and other private companies until fiscal years beginning after December 15, 2022 for SEC filers that are eligible to be smaller reporting companies under the SEC’s definition, as well as private companies and not-for-profit entities. The Company is currently evaluating the new guidance and has not yet determined whether the adoption of the new standard will have a material impact on its consolidated financial statements or the method of adoption. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The guidance was issued as improvements to ASU No. 2016-13 described above. The vintage disclosure changes require an entity to disclose current-period gross write-offs by year of origination for financing receivables. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The amendments should be applied prospectively. Early adoption of the amendments is permitted, including adoption in an interim period. The amendments will impact our disclosures but will not otherwise impact the consolidated financial statements. The Company is currently evaluating the new guidance. Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.
Basis of Presentation | Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (all of which are of a normal recurring nature) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or for any other future period. These unaudited consolidated financial statements and the unaudited condensed notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2023. |
