Founded in 1951 and running quietly out of Vancouver, Washington, BBSI has turned the least glamorous parts of running a business - payroll, workers' comp, HR paperwork - into a $1.2 billion operation built around one idea: put a real local team in the room.
There is a moment in the life of almost every small business that no one warns you about. It doesn't arrive with a competitor or a market crash. It arrives with a ninth employee, a workers' compensation claim, a payroll tax notice, and an HR complaint you didn't see coming - all in the same month. The product was never the problem. The paperwork was. BBSI - Barrett Business Services, Inc. - built a billion-dollar company on that exact moment.
Most people have never heard of it. That is part of the story. From an office park in Vancouver, Washington, just across the Columbia River from Portland, BBSI acts as the co-employer of record for roughly 8,000 small and mid-sized businesses. It runs their payroll, carries their workers' compensation, administers their benefits, manages their HR, and coaches their safety programs. In 2024, doing the work almost no founder wants to do, it generated about $1.24 billion in revenue.
BBSI is a PEO - a Professional Employer Organization. The term is dry; the mechanism is not. Under a co-employment arrangement, BBSI becomes the administrative employer of a client's worksite employees. On paper, those workers are shared: BBSI handles payroll, payroll taxes, workers' compensation, benefits, and compliance, while the business owner keeps full control of who they hire, what they build, and how they run the floor.
The practical effect is that a 20-person contractor suddenly has the HR department, risk manager, and benefits desk of a company ten times its size - without hiring any of them. That is the pitch, and it explains why the model tends to sell hardest in industries where a single mistake is expensive.
BBSI's clients are overwhelmingly small and mid-sized businesses, concentrated in the sectors where employment is heavy and risk is real: construction, manufacturing, healthcare, transportation and logistics, and professional services. These are firms with real payrolls and thin administrative staff - the exact profile that hits the wall the fastest.
The relationship is deliberately unglamorous and deliberately human. Rather than routing a new client to a login screen, BBSI pairs them with a local team - typically a Business Partner, an HR consultant, a payroll specialist, and a risk consultant - who meet in person and learn the business by name. Around 900 consultants staff more than 50 branches to make that possible.
The PEO market is crowded. ADP TotalSource, Insperity, TriNet, Paychex, Justworks, and Vensure all sell versions of the same promise. Many of them compete on software - clean dashboards, self-service, automation. BBSI competes on the opposite: it bets that a growing business would rather call a person who knows its safety record than click through a help center.
That local, decentralized branch model is the company's real moat. Software can be copied in a quarter. A risk consultant who has walked a client's warehouse floor and cut their comp claims cannot be. It is also why BBSI leans into the hard industries competitors sometimes avoid - the ones where safety expertise directly lowers cost.
BBSI's revenue model is unusually aligned with its customers. It bills clients on a gross-billings basis that bundles payroll, payroll taxes, workers' compensation, and a service fee. Because those billings scale with a client's total payroll, BBSI grows automatically when its customers hire. Add staffing, benefits, and retirement products on top, and you have a company whose fortunes rise with the small-business economy it serves.
The numbers in 2024 reflected it. Fourth-quarter revenue rose 10% year over year to $304.8 million, net income for the quarter came in at $16.8 million, and full-year revenue reached roughly $1.24 billion. CEO Gary Kramer credited record worksite-employee additions from new clients and a strong year-end season for the BBSI Benefits health offering.
BBSI is older than the interstate highway system. Its roots trace to 1951, and its modern shape formed when William W. Sherertz acquired the company in 1963 and incorporated it in 1965. For decades it was a West Coast staffing firm concentrated in Oregon and Washington. Sherertz took it public on NASDAQ in 1993 and, over three decades, grew a tiny temporary-help agency into a nationwide operation.
The pivot from staffing to PEO was not a rebrand. It was a re-engineering of the business - taking on payroll, taxes, and workers' comp under co-employment, and accepting the risk that came with it. When Sherertz died unexpectedly in 2011, the company reset rather than unraveled, doubling down on the local-team model that still defines it.
Most PEOs are privately held, which makes the industry hard to read from the outside. BBSI is one of the few that is publicly traded, giving customers, competitors, and curious outsiders a rare window into how the co-employment business actually works. It is ESAC-accredited and SOC 1 certified - the kind of credentials that matter to a small-business owner handing over their payroll and their people.
Its place in the market is specific: not the biggest name, not the flashiest platform, but the operator that decided the relationship - the local team in the room - was worth more than the interface. In an industry racing to automate, that is a contrarian bet. Seventy-plus years in, it is still paying.
