Publicly traded, branch-based PEO built around workers' compensation and local business consulting, heavily weighted to California and the West
BBSI (Barrett Business Services) is an ESAC-accredited PEO that quotes companies of Small and mid-size businesses; 2025 figures imply an average near 17 worksite employees per client (sweet spot: 10 to 100), most often California and West Coast employers. A NASDAQ-listed PEO of real scale, 138,218 average worksite employees in 2025, that pairs ESAC accreditation with a local branch service model and strong workers' compensation capability. Not IRS CPEO certified, and the business is concentrated in California, which supplied about 72% of 2025 revenues.
Our take
BBSI is the PEO we reach for when workers' compensation and on-the-ground service matter more than software. Being public means we can read the 10-K rather than take a private PEO's word on financial stability, and the ESAC accreditation plus SOC 1 testing back that up. Two things we always flag: they are not on the IRS CPEO list, so buyers who screen on the federal tax-liability shift should know that going in, and the book is concentrated in California, which means the branch bench is thinner once a client's footprint moves east. For a West Coast construction, manufacturing or transportation employer, we think the risk expertise and local team model usually justify the tradeoff.
