Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	NATURE OF OPERATIONS BG Staffing, Inc. is a national provider of temporary staffing services 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., and BG California Finance & Accounting Staffing, Inc. (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. The Professional segment provides skilled field talent on a nationwide basis for information technology ("IT") and finance and accounting client partner projects. The Light Industrial segment provides field talent primarily to logistics, distribution, and call center client partners needing a flexible workforce in Illinois, Wisconsin, New Mexico, Texas, Tennessee and Mississippi. 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 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 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. In addition, our cost of services typically increases in the first quarter primarily due to the reset of payroll taxes.
