Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	NATURE OF OPERATIONS BGSF, Inc. provides consulting, managed services, and professional workforce solutions to a variety of industries through its various divisions in information technology (“IT”), Finance & Accounting, Managed Services, and Property Management (formally known as Real Estate which includes apartment communities and commercial buildings) (collectively, with its consolidated subsidiaries, the “Company”). On March 21, 2022, the Company completed the sale of substantially all its Light Industrial segment (“InStaff”) assets to Jobandtalent, through the wholly-owned subsidiary, Sentech Engineering Services, Inc. Instaff's financial results for reported periods have been reflected in our Consolidated Statements of Operations and Comprehensive Income (Loss) and Consolidated Statements of Cash Flows as discontinued operations. See “Note 4 - Discontinued Operations” in the Consolidated Financial Statements included elsewhere in this report for additional information. On December 12, 2022, the Company acquired substantially all of the assets, and assumed certain of the liabilities of Horn Solutions, Inc. and Horn Solutions Dallas, LLC (collectively “Horn Solutions”). See “Note 3- Acquisitions.” On April 24, 2023, the Company acquired substantially all of the assets and assumed certain of the liabilities of Arroyo Consulting, LLC ("Arroyo Consulting"), which is a nearshore/offshore workforce solutions firm that specializes in IT and software development with operations in the United States, Colombia, and India. See “Note 3- Acquisitions.” The Company currently operates primarily within the United States of America (“U.S.”) through the Property Management and Professional segments. The Property Management segment provides office and maintenance field talent to various apartment communities and commercial buildings in 38 states and D.C., via property management companies responsible for the apartment communities' and commercial buildings' day-to-day operations. The Professional segment provides specialized talent and business consultants for IT, managed services, finance, accounting, legal, and human resources. The segment operates across the U.S. in three divisions, IT, Managed Services, and Finance & Accounting, with the IT division providing additional nearshore/offshore solutions in Colombia and India. The Company normally experiences seasonal fluctuations. The quarterly operating results are affected by the number of billing days in a quarter, as well as the seasonality of client partners’ businesses. Demand for the Property Management workforce solutions has historically increased in the second quarter and is highest during the third quarter of the year due to the increased turns in multifamily units during the summer months when schools are not in session. Overall first quarter demand can be affected by adverse weather conditions in the winter months. In addition, the Company's cost of services typically increases in the first quarter primarily due to the reset of payroll taxes. The current inflationary environment and related interest rate impacts continue to have an adverse impact on the economy and market conditions. These factors may continue to impact labor markets by reducing demand for the Company's workforce solutions, increasing early terminations, or diminishing projects. As a result, the Company's business, financial condition and results of operations may be negatively affected. The accompanying unaudited consolidated financial statements have been prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“GAAP”), pursuant to the applicable rules and regulations of the SEC. The information furnished herein reflects all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary to present a fair statement of the financial position and operating results of the Company as of and for the respective periods. However, these operating results are not necessarily indicative of the results expected for a full fiscal year or any other future period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, management of the Company believes, to the best of its knowledge, that the disclosures herein are adequate to make the information presented not misleading. The Company has determined that there were no subsequent events that would require disclosure or adjustments to the accompanying unaudited consolidated financial statements through the date the financial statements were issued, except for the disclosure in Note 16. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the fiscal year ended January 1, 2023, included in its Annual Report on Form 10-K.
