How staffing services are actually bought in the USA
The buying group is wider than the hiring manager
A hiring manager feels the pain, but a talent acquisition lead usually runs the process and procurement often controls the agreement. Any one of them can stall a deal. Agencies that track only the hiring manager get enthusiastic conversations that never convert into a signed rate card, and agencies that track only procurement get onto a supplier list nobody uses.
Winning the account and winning the requisition are separate events
Getting approved as a supplier is the beginning, not the finish. The real revenue question is whether requisitions actually flow afterwards, and that depends on the hiring manager relationship rather than the paperwork. Plenty of agencies sit on approved vendor lists with no orders at all.
