What buyers in this trade should ask
Professional services firms — attorneys, accountants, consultants, architects, agencies — are the cleanest PEO candidate on paper and the easiest to mis-buy. The workforce is salaried, office-bound and small, which keeps workers' compensation simple and class codes uncomplicated. The reason these firms consider a PEO at all is benefits. A ten-person consultancy cannot command the carrier attention of a large employer, and the PEO's pool is the point of the arrangement: the firm trades its tiny group for access to plans underwritten across the provider's entire book of business.
That works only if the plan actually fits. Compare the provider's medical plan designs and contribution structure against what your people use, not against the headline. Firms with heavy professional-liability culture tend to care as much about employment practices liability insurance — whether it is included, with what limits and exclusions — as about the medical plan. Ask for the EPLI certificate and read the exclusion list.
Partnership and profit-share structures are the second thing to check. A PEO's payroll engine has to handle draw-based partner compensation, distributed profit, and multiple equity tiers without turning them into ordinary wages. Ask the provider to show you a partner-structure payroll run before you sign, and get the treatment of bonuses in writing.
The third question is client-facing confidentiality. The provider's payroll and HR staff handle sensitive client data as part of the arrangement; ask where the data lives, who can see it, and what the provider's own security controls are. A firm that holds client money or privilege is outsourcing a compliance surface, not buying a commodity.
What the May 2025 BLS data shows. The Occupational Employment and Wage Statistics program places this trade in NAICS 54 and reports national employment of 10,800,470 with an all-occupations median annual wage of $87,530 and a mean of $108,640 in the sector for May 2025. The sector line is a useful sanity check for quote modeling because professional-services payroll runs heavily toward salaried staff, so the median tracks the actual pay profile of most firms in this trade more closely than it does in hourly sectors. What remains unverified is provider-specific documentation: EPLI inclusion and limits for professional-services clients, partner and draw payroll handling, and security and data-location statements. Each of those stays on the research queue until it carries a primary source and a verification date. Fee unbundling matters most here, because the office class codes are quiet and the administrative fee is the surface that actually varies.
