Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and Basis of Presentation	NOTE 1 – THE COMPANY AND BASIS OF PRESENTATION Nature of Operations One Stop Systems, Inc. (“we,” “our,” “OSS,” or the “Company”) was originally incorporated as a California corporation in 1999, after initially being formed as a California limited liability company in 1998. On December 14, 2017, the Company was reincorporated as a Delaware corporation in connection with its initial public offering. The Company designs, manufactures, and markets specialized rugged high-performance compute, high speed switch fabrics and storage systems, which are designed to target edge applications for artificial intelligence (“AI”)/machine learning (“ML”), sensor processing, sensor fusion and autonomy. The Company markets its products to manufacturers of equipment used for autonomous vehicles, medical, industrial, and military applications, with special focus on platforms that move, such as planes, trucks, ships, submarines and mobile datacenters or command posts where sensor processing, sensor fusion, AI and ML are integrated to support such applications. During the year ended December 31, 2015, the Company formed a wholly owned subsidiary in Germany, One Stop Systems, GmbH (“OSS GmbH”). In July 2016, the Company acquired Mission Technologies Group, Inc. (“Magma”) and its operations that complemented OSS' manufacture of custom high-performance compute servers. On August 31, 2018, the Company acquired Concept Development Inc. (“CDI”) located in Irvine, California. CDI specialized in the design and manufacture of custom high-performance computing systems for airborne in-flight entertainment, flight safety equipment, and networking systems. CDI’s business was fully integrated into the core operations of the Company as of June 1, 2020. On October 31, 2018, OSS GmbH acquired 100% of the outstanding equity of Bressner Technology GmbH, a limited liability company registered under the laws of Germany and located near Munich, Germany (“Bressner”). Bressner designs and manufactures standard and customized servers, panel PCs, and PCIe accelerator systems. It also operates as a systems integrator with standard and custom all in one hardware systems and components. In addition, Bressner serves as a channel to market for OSS ruggedized datacenter level compute and storage products to the European and Middle Eastern markets. The Company's results of operations for the year ended December 31, 2023 were negatively impacted by the loss of business from a legacy media and entertainment. In the second quarter of 2023, the Company completed and fulfilled substantially all of its orders associated with this customer and does not anticipate significant business from this customer in the future. This resulted from an acceleration in such customer’s investment in cloud technology and a drive towards less intelligent compute capability at the edge to reduce the costs of their componentry. This is particularly true of their virtual products, which do not require the same level of ruggedization, as this system is not typically operated in harsh environments and for which software is being developed to provide a real-time cloud solution. With the Company's shifted focus on the development and sale of edge computing solutions, we have significantly increased our efforts to penetrate the military and defense sectors in particular. With the hiring of Michael Knowles and Robert Kalebaugh, each of whom has extensive experience in contracting in the defense industry, as our new president and chief executive officer and vice president of sales, respectively, we have further increased our emphasis and focus on the pursuit of revenue opportunities with major defense contractors and the military. The negative impact on the global economy and capital markets resulting from geopolitical instability caused in part by the ongoing military conflict between Russia and Ukraine and Israel and Hamas, inflation and Federal Reserve and European Central Bank interest rate policy, and the weakness in the European and more specifically the German economy have contributed to economic uncertainty, which has negatively affected our operations. Component shortages and increased lead times from Taiwan, coupled with rising political tensions in Taiwan, resulted in supply chain delays and shortages that negatively impacted the Bressner business during the year to include the weakness of the European and German economy. The risk of a recession in the U.S. remains, and volatility and recessionary conditions in Europe, and in Germany in particular, are expected to remain a concern for the near term. Additionally, it is possible that U.S. policy changes and uncertainty about such changes, including changes and uncertainty as a result of the US presidential administration change, could increase market volatility and currency exchange rate fluctuations. As a result of the foregoing, there is continued economic uncertainty and volatility in the capital markets in the near term that could negatively affect our operations. We are continuing to experience increased pricing, long lead-times, unavailability of certain product and limited supplies, protracted delivery dates, changes in minimum order quantities to secure product, and/or shortages of certain parts and supplies that are necessary components for the products and services we offer to our customers. This was particularly true for products and supplies sourced from Taiwan in the most recent fiscal quarter. As a result, the Company is continuing to carry increased inventory balances to ensure availability of necessary products and to secure pricing. These global issues and concerns regarding general economic decline or recession are impacting our business as well as some of our customers, who are continuing to experience downturns or uncertainty in their own business operations and revenue, and as a result, these customers may need to decrease or delay their technology spending, request pricing concessions or payment extensions, or seek to renegotiate their contracts. During the year ended December 31, 2024, the Company experienced delays in orders due to certain customers’ funding or program delays. If such decreases in orders or postponements continue in the future, or we experience cancellations of orders, our operating results will be further impacted, and our revenues may decline in future periods. These global issues and events may also have the effect of heightening many risks associated with our customers and supply chain. We may take further actions that alter our operations from time to time, or which we determine are in our best interests. In addition, we may decide to postpone or abandon planned investments in our business in response to changes in our business, which may impact our ability to attract and retain customers and our rate of innovation, either of which could harm our business. As a result of these global issues, it has been difficult to accurately forecast our revenues or financial results, especially given the near and long-term impacts of the economic and geopolitical issues, inflation, and the potential for continued weakness in the German economy. In addition, while the potential impact and duration of these issues on the economy and our business may be difficult to assess or predict, these world events have resulted in, and may continue to result in, significant disruption of global financial markets, and may reduce our ability to access additional capital, which could negatively affect our liquidity in the future. Our results of operations could be materially below our forecasts as well, which could adversely affect our results of operations, disappoint analysts and investors, or cause our stock price to decline. Management’s plans with respect to the above are to continue their efforts towards responding to the changing economic landscape and to continue to control costs, conserve cash, and strengthen margins through the introduction of new products and solutions focusing on AI compute capabilities for military and industrial applications. Basis of Presentation The accompanying financial statements have been prepared on an accrual basis of accounting in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”), as set forth in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”). Reclassifications Certain prior year amounts have been reclassified to conform with the current year presentation. In the current year, the Company began disclosing as a separate component of revenue and cost of sales, the amounts related to customer funded development revenue and costs. Customer funded development is revenue from customers for which the Company's performance obligations are satisfied over time and for which the customer receives benefits as the Company performs. Products revenue performance obligations are typically satisfied at a point in time, predominately upon shipment. Principles of Consolidation The accompanying consolidated financial statements include the accounts of OSS, which include the acquisition of CDI, and its wholly owned subsidiary, OSS GmbH, which also includes the acquisition of Bressner. Intercompany balances and transactions have been eliminated in consolidation.
