Company background: BBSI (Barrett Business Services).
Barrett Business Services, Inc., BBSI, was incorporated in Maryland in 1965, traces its origins to a 1951 staffing business and is headquartered in Vancouver, Washington. It trades on NASDAQ under BBSI, and as of December 31, 2025 it employed 3,197 people, of whom 896 were management, sales and administrative staff and 2,297 were staffing services employees.
By worksite employees it is one of the largest PEOs in the country: 138,218 average worksite employees in 2025 across more than 8,200 PEO clients, which implies an average client of roughly 17 employees. The model is decentralized. BBSI runs 45 branches in 15 states and assigns each client a stated four-specialist team covering payroll, HR, risk and business strategy, so an owner-led small business gets operating advice alongside its HR.
Being public means the diligence a buyer normally has to take on faith is in a 10-K: audited financials, quarterly reporting and management's own description of the business. That filing is also where the concentration shows. California produced most of BBSI's 2025 revenue, and management describes new IT product launches as a 2026 roadmap item. BBSI is ESAC accredited and SOC 1 certified; it is not on the IRS CPEO list.
