Staffing revenue doesn't read like the rest of business services: the ~$360B is gross bill-through — an agency invoices the client for the temp's wages plus a markup, so most of it is pass-through and the real business is the thin margin on top (3–8% EBITDA in volume staffing). It also inflates the surface metrics — ~152 employees per firm counts armies of placed temps, not office staff. PEO co-employment ($198B, in the EOR segment below) is deliberately excluded from this figure: its receipts are almost entirely the wages of client workers it processes, and folding them in would nearly double the headline with pure pass-through. This is the least fragmented corner of the sector — nearly 5% of firms top 500 employees, versus well under 1% across the advisory segments.
