Every vendor promises. Make yours prove.
Read five staffing proposals side by side and they blur into one: great people, fast fills, true partnership, safety first. Every vendor promises the same things because promises are free. The difference between partners shows up later, in what they can prove.
The questions that separate them
Before signing anything, ask for four things in writing. First, fill-rate history: orders filled against orders placed, by site, for a comparable account. Second, retention: how long their people actually stay at client sites, not company-wide averages. Third, reporting: what you will see, how often, and whether it's the same data they see internally. Fourth, accountability: what specifically happens when a metric is missed—who calls whom, by when, with what fix.
A partner who delivers well answers in a day. A partner who sells well changes the subject to culture.
Verification is a posture, not a feature
The deeper tell is whether your partner expects to be measured. An operation that verifies its own delivery—hours, coverage, performance against agreed criteria—behaves differently than one that reports when asked. Verification means the uncomfortable number surfaces on their cadence, not when you find it. It means success criteria exist in writing before anyone starts, so "how's it going" has an answer that isn't a feeling.
This is the standard we hold ourselves to, and the honest version of this article admits that's a claim too. So treat it like one: ask us the same four questions, and expect the same one-day answer.
The one-page test
Take your current vendor's last quarterly review. If it fits on one page of numbers you could defend to your CFO—fill rate, retention, hours verified, incidents, criteria met or missed—you have a partner. If it's twelve slides of relationship, you have a promise. Work deserves proof.
