Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	NATURE OF OPERATIONS BG Staffing, Inc. is a national provider of workforce solutions that operates, along with its wholly owned subsidiaries BG Staffing, LLC, B G Staff Services Inc., BG Personnel, LP, BG Finance and Accounting, Inc., BG California IT Staffing, Inc., BG California Multifamily Staffing, Inc., BG California Finance & Accounting Staffing, Inc., EdgeRock Technology Holdings, Inc. and EdgeRock Technologies, LLC (collectively, the “Company”), primarily within the United States of America in three industry segments: Real Estate, Professional, and Light Industrial. The Real Estate segment provides office and maintenance field talent to various apartment communities and commercial buildings in 29 states, via property management companies responsible for the apartment communities' and commercial buildings' day-to-day operations. Our Real Estate segment operates through two divisions, BG Multifamily and BG Talent. The Professional segment provides skilled field talent on a nationwide basis for information technology (“IT”) and finance, accounting, legal and human resource client partner projects. Our Professional segment operates through various divisions including Extrinsic, American Partners, Donovan & Watkins, Vision Technology Services, Zycron, Smart Resources, L.J. Kushner & Associates, and EdgeRock Technology Partners. The Light Industrial segment provides field talent primarily to manufacturing, distribution, logistics, and call center client partners needing a flexible workforce in 7 states. Our Light Industrial segment operates through our InStaff division. Our business experiences seasonal fluctuations. Our quarterly operating results are affected by the number of billing days in a quarter, as well as the seasonality of our client partners’ business. Demand for our Real Estate staffing services typically increase in the second 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. Demand for our Light Industrial staffing services typically increases during the third quarter of the year and peaks in the fourth quarter due to increases in the demand for holiday help. Overall demand can be affected by adverse weather conditions in the winter months as well as fluctuations in client partner demand. In addition, our cost of services typically increases in the first quarter primarily due to the reset of payroll taxes. The Company has adjusted, and continues to monitor and change, its operations in response to a novel strain of coronavirus (“COVID-19”) in all of its segment, client partner, and Home Office locations. The extent of the impact from the outbreak on its operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, its impact on the Company's client partners and the range of governmental and community reactions to the pandemic, which are uncertain and cannot be fully predicted at this time.
