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 high-performance computing modules and systems, which are designed to target edge computing deployments. The Company markets its products to manufacturers of automated equipment used for media and entertainment, medical, industrial, and military applications. During the year ended December 31, 2015, the Company formed a wholly-owned subsidiary in Germany, One Stop Systems, GmbH (“OSS GmbH”). During July 2016, the Company acquired Mission Technologies Group, Inc. (“Magma”) and its operations. On August 31, 2018, the Company acquired Concept Development Inc. (“CDI”) located in Irvine, California. CDI specializes in the design and manufacture of custom high-performance computing systems for airborne in-flight entertainment and networking systems. CDI has been fully integrated into the core operations of OSS as of June 1, 2020. On October 31, 2018, OSS GmbH acquired 100% of the outstanding stock of Bressner Technology GmbH, a Germany limited liability company located near Munich, Germany (“Bressner”). Bressner provides standard and customized servers, panel PCs, and PCIe expansion systems. Bressner also provides manufacturing, test, sales and marketing services for customers throughout Europe. The Company’s revenue growth during fiscal year 2020 slowed due to the effects of COVID-19 and, although it rebounded somewhat in 2021, it has not yet fully recovered due to, amongst other things, venue constraints on large group gatherings, which affected the Company’s media and entertainment business. However, through a reduction in force and strict cost containment, the Company was able to mitigate the effects, to some degree, of the reduced revenue attributable to the economic impact of COVID-19. Despite global efforts to slow the spread of the virus and to mitigate its effects, COVID-19 continues to impact worldwide economic activity, and the ongoing effects of the COVID-19 pandemic has adversely impacted, and may continue to adversely impact, many aspects of our business. In response to the COVID-19 pandemic, many state, local, and foreign governments have put in place restrictions to control the spread of the disease. Such restrictions, or the perception that further restrictions could occur, have resulted in business closures, work stoppages, slowdowns, delays, work-from-home policies, travel restrictions, and cancellation or postponement of events, among other effects that impacted productivity and disrupted our operations and those of our partners, suppliers, contractors, and customers. One way that COVID-19 has directly affected our operations is that we have experienced increased pricing and/or shortages of certain parts and supplies that are necessary components to the products and services we offer to our customers, and as a result, are experiencing longer lead-times. COVID-19 has indirectly affected our operations as well. For instance, some of our customers experienced downturns or uncertainty in their own business operations and revenue, and as a result, these customers have (and may continue to) decreased or delayed their technology spending, requested pricing concessions or payment extensions, or seek to renegotiate their contracts. During the pandemic, as state, local, and foreign governments implemented (and may continue to implement) preventative measures to contain or mitigate the outbreak of COVID-19, the usage of our products and services fluctuated, and we cannot predict how usage levels will continue to be impacted by these preventative measures. There is no assurance that customers will continue to use our products and services, or to the same extent, as the COVID-19 pandemic begins to taper off or after it ends. As a result, it has been difficult to accurately forecast our revenues or financial results, especially given that the near and long term impact of the pandemic remains uncertain. In addition, while the potential impact and duration of the COVID-19 pandemic on the economy and our business may be difficult to assess or predict, the pandemic has 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. Furthermore, a decrease in orders in a given period could negatively affect our revenues in future periods. The COVID-19 pandemic 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 as may be required by federal, state, or local authorities from time to time, or which we determine are in our best interests. While much of our operations can be performed remotely, certain activities often require personnel to be on-site, and our ability to carry out these activities has been, and may continue to be negatively impacted if our employees or local personnel are not able to travel. In addition, for activities that may be conducted remotely, there is no guarantee that we will be as effective while working remotely because our team is dispersed and many employees and their families have been negatively affected, mentally or physically, by the COVID-19 pandemic. Decreased effectiveness and availability of our team could harm our business. In addition, we may decide to postpone or cancel planned investments in our business in response to changes in our business resulting from the spread of COVID-19, which may impact our ability to attract and retain customers and our rate of innovation, either of which could harm our business. We do not yet know the full extent of potential delays or impacts on our business, operations, or the global economy. Although our business continued to be negatively impacted by the pandemic in 2021, our results of operations predominantly improved as compared to 2020. Currently, we are experiencing unavailability of product and limited supplies, protracted delivery dates for componentry, increasing product costs, and changes in minimum order quantities to secure product. As a result, the Company is carrying increased inventory balances to ensure availability of necessary products and to secure pricing. Additionally, products that are in the “work-in-process” stage and our inventory of finished goods have increased due to as the timing and availability of certain componentry necessary to complete our products. While there have recently been vaccines developed and administered, and certain government orders and restrictions in particular cities, counties, and states have been lifted as the spread of COVID-19 starts to be contained and mitigated, we cannot predict the timing of the vaccine roll-out globally or the efficacy of such vaccines, including against variants of the virus, and we do not yet know how businesses, customers, contractors, suppliers, or our partners will operate in a post COVID-19 environment, especially if additional or supplemental governmental orders, limitations, and restrictions are reinstated. There may be additional costs or impacts to our business and operations, including when we are able to resume in-person activities, travel, and events. In addition, there is no guarantee that a future outbreak of this or any other widespread epidemics will not occur, or that the global economy will recover, either of which could harm our business. Management’s plans with respect to the above are to continue their efforts towards responding to the changing economic landscape attributable to COVID-19, to continue to control costs, conserve cash, strengthen margins, and improve company-wide execution. Specific actions implemented in 2020 by management in response to this effort included a reduction in force, a limited freeze on hiring, reduced work week, minimized overtime, travel and entertainment, and contractor costs.
