Characteristics

  • Labor-intensive: payroll is 77% of revenue, so margin comes from utilization, not scale
  • Deep strategic-buyer pool: 467 firms exceed 500 employees, so a scaled asset has trade buyers
  • Reported revenue is largely pass-through; value-add is the admin/benefit margin.
  • Co-employment depth makes the relationship sticky and switching costly.
  • Global EOR platforms have rapidly expanded cross-border employment.

PEOs concentrate in business-friendly, low-regulation states rather than population centers: Oklahoma carries 2.6 times its expected share and Michigan 2.1 times, with Utah and Arizona close behind. The pattern reflects where small employers most value offloading payroll, benefits and compliance, and where PEOs have historically built their books; it is notably not the coastal HR-services map.
