The Company and Basis of Presen

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 completed and fulfilled all of the outstanding orders associated with its long-term media and entertainment customer during the year ended December 31, 2023, and does not anticipate further business from this customer in the future. This resulted from an acceleration in the 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 customer’s transition to cloud solutions had a negative impact on the Company’s results of operations for the year ended December 31, 2023. With the Company's shifted focus to the development and sale of AI Transportables, we have significantly increased our efforts to penetrate the military and defense sectors in particular. With the recent 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 lingering negative impacts of the COVID-19 pandemic and the impact on the global economy and capital markets resulting from the geopolitical instability caused in part by the ongoing military conflict between Russia and Ukraine and Israel and Hamas, including inflation and Federal Reserve and European Central Bank interest rate increases, have contributed to global supply chain issues and economic uncertainty, which has negatively affected our operations. The risk of a recession in the U.S. remains elevated and volatility and recessionary conditions in Europe, and in particular in Germany, are expected to remain a concern for the near term. 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. 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 quarter ended March 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, as well as other factors discussed in these notes, 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, the Federal Reserve and European Central Bank interest rate increases and the potential for recession in both the United States and Germany. 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, to continue to control costs, conserve cash, strengthen margins through the introduction of new product lines focusing on AI compute capabilities for military and industrial applications, autonomous truck diving and improve company-wide execution. Basis of Presentation The accompanying consolidated 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”). The unaudited consolidated financial statements herein have been prepared by the Company pursuant to the rules and regulations of the SEC. The accompanying interim unaudited consolidated financial statements have been prepared under the presumption that users of the interim financial information have either read or have access to the audited consolidated financial statements for the latest year ended December 31, 2023. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the December 31, 2023 audited consolidated financial statements have been omitted from these interim unaudited consolidated financial statements. The Company’s management has evaluated all subsequent events and transactions through the date of filing this Quarterly Report. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in the accompanying condensed consolidated financial statements. For further information, refer to the audited consolidated financial statements and notes for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 21, 2024. 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 operating results of its wholly owned subsidiary, OSS GmbH, and its wholly owned subsidiary Bressner. Intercompany balances and transactions have been eliminated in consolidation.

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES There have been no changes to our accounting policies disclosed in our audited consolidated financial statements and the related notes for the year ended December 31, 2023. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and assumptions. On an ongoing basis, our management evaluates these estimates and assumptions, including those related to determination of standalone selling prices of our products and services, allowance for credit losses and sales reserves, income tax valuations, stock-based compensation, goodwill, intangible assets and inventory valuations and recoverability. We base our estimates on historical data and experience, as well as various other factors that our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Due to the lingering effects of the COVID-19 pandemic, Ukraine war, the escalating conflicts in the middle east, inflationary pressures, other macroeconomic factors and the loss of our media and entertainment customer, there has been uncertainty and disruption in the global economy, financial markets and our ongoing operations. We are not aware of any specific event or circumstance that would require an update to our estimates or assumptions or a revision of the carrying value of our assets or liabilities as of the date of this Quarterly Report. These estimates and assumptions may change as new events occur and additional information is obtained. As a result, actual results could differ materially from these estimates and assumptions. Recent Accounting Pronouncements On November 27, 2023, the FASB issued ASU 2023-07 "Segment Reporting (Topic 280): Improvements to reportable segment disclosures." This amendment enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable “investors to better understand an entity’s overall performance” and assess “potential future cash flows.” The adoption of this amendment is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Management does not anticipate any material impact on the consolidated financial statements.

Stockholders Equity Note [Abstract]
Stockholders' Equity	NOTE 8 – STOCKHOLDERS’ EQUITY The Company’s amended and restated certificate of incorporation, filed with the Delaware Secretary of State on December 14, 2017, authorizes the Company to issue 10,000,000 shares of preferred stock and 50,000,000 shares of common stock. 2017 Equity Incentive Plan On October 10, 2017, the Company’s board of directors approved and adopted the Company’s 2017 Equity Incentive Plan (as amended to date, the “2017 Plan”), subject to stockholder approval thereof. On December 18, 2017, the Company’s stockholders approved the 2017 Plan. The 2017 Plan allows for the grant of a variety of equity vehicles to provide flexibility in the grant and issuance of equity awards, including stock options, unrestricted stock grants, restricted stock units (“RSUs”), stock bonuses and performance-based awards. An aggregate of 1,500,000 shares of common stock were initially reserved for issuance under the 2017 Plan. On June 24, 2020, the Company amended the 2017 Plan to increase the maximum number of shares of common stock with respect to one or more Stock Awards (as defined in the 2017 Plan) that may be granted to any one participant under the 2017 Plan during any calendar year from 500,000 shares to 1,000,000 shares. The amendment did not increase the total number of shares of common stock authorized for issuance under the 2017 Plan and did not require stockholder approval. On May 19, 2021, the Company’s stockholders approved the Company’s proposal to increase the number of shares authorized for issuance under the 2017 Plan from 1,500,000 shares to 3,000,000 shares of common stock of the Company pursuant to the terms and conditions of the 2017 Plan. The amendment took effect upon receipt of stockholder approval. On March 15, 2024, the Company’s board of directors unanimously approved, subject to stockholder approval, an amendment to the 2017 Plan (the “Plan Amendment”), which, if approved by our stockholders, would result in an increase in the number of shares of common stock authorized for issuance thereunder from 3,000,000 to 5,000,000 shares. The Plan Amendment will be presented to stockholders for approval at the Company’s 2024 Annual Meeting of Stockholders. If approved by stockholders at the meeting, the Plan Amendment will be effective as of the date of such approval.

Restricted Stock Units RSUs may be granted at the discretion of the compensation committee of the Company's board of directors under the 2017 Plan in connection with the hiring and retention of personnel and are subject to certain conditions.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated 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”). The unaudited consolidated financial statements herein have been prepared by the Company pursuant to the rules and regulations of the SEC. The accompanying interim unaudited consolidated financial statements have been prepared under the presumption that users of the interim financial information have either read or have access to the audited consolidated financial statements for the latest year ended December 31, 2023. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the December 31, 2023 audited consolidated financial statements have been omitted from these interim unaudited consolidated financial statements. The Company’s management has evaluated all subsequent events and transactions through the date of filing this Quarterly Report. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in the accompanying condensed consolidated financial statements. For further information, refer to the audited consolidated financial statements and notes for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 21, 2024.
Reclassifications	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	Principles of Consolidation The accompanying consolidated financial statements include the accounts of OSS, which include the operating results of its wholly owned subsidiary, OSS GmbH, and its wholly owned subsidiary Bressner. Intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and assumptions. On an ongoing basis, our management evaluates these estimates and assumptions, including those related to determination of standalone selling prices of our products and services, allowance for credit losses and sales reserves, income tax valuations, stock-based compensation, goodwill, intangible assets and inventory valuations and recoverability. We base our estimates on historical data and experience, as well as various other factors that our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Due to the lingering effects of the COVID-19 pandemic, Ukraine war, the escalating conflicts in the middle east, inflationary pressures, other macroeconomic factors and the loss of our media and entertainment customer, there has been uncertainty and disruption in the global economy, financial markets and our ongoing operations. We are not aware of any specific event or circumstance that would require an update to our estimates or assumptions or a revision of the carrying value of our assets or liabilities as of the date of this Quarterly Report. These estimates and assumptions may change as new events occur and additional information is obtained. As a result, actual results could differ materially from these estimates and assumptions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On November 27, 2023, the FASB issued ASU 2023-07 "Segment Reporting (Topic 280): Improvements to reportable segment disclosures." This amendment enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable “investors to better understand an entity’s overall performance” and assess “potential future cash flows.” The adoption of this amendment is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Management does not anticipate any material impact on the consolidated financial statements.
