BBSI (Barrett Business Services) Review 2026

Publicly traded, branch-based PEO built around workers' compensation and local business consulting, heavily weighted to California and the West

Founded: 1965·Best for: Small and mid-size businesses; 2025 figures imply an average near 17 worksite employees per client (sweet spot: 10 to 100)·Custom rate quoted per client, driven by headcount, workforce mix, turnover, loss history, job-function risk and experience modification; BBSI states it does not use flat or generic pricing tiers

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.

What BBSI (Barrett Business Services) does well

  • One of the largest PEOs in the country by worksite employees, with 138,218 average WSEs in 2025 and gross billings of $9.04 billion
  • Public-company disclosure: a 10-K, audited financials and quarterly reporting give buyers unusual visibility into the PEO's own solvency
  • ESAC accredited and SOC 1 certified, so financial assurance and control testing are independently verified
  • Decentralized branch model, 45 branches in 15 states with a stated four-specialist team per client covering payroll, HR, risk and business strategy
  • Deep workers' compensation capability, including self-insurance in Colorado, Maryland, Ohio and Oregon and a captive insurer for Arizona and Utah, which supports higher-hazard risk classes

Watch-outs and limitations

  • Not on the IRS CPEO list, so there is no federal sole-liability shift for employment taxes
  • Heavy geographic concentration: California produced roughly 72% of 2025 revenues
  • Technology is functional rather than leading; management describes new IT product launches as a 2026 roadmap item
  • No published pricing, and rates are explicitly built around risk profile and experience modification rather than a standard tier
