What Is Fill Rate?
Fill rate is the percentage of a staffing or recruiting firm's open job orders that are actually filled with a placed candidate over a given period, the standard metric for how successfully a firm converts the requisitions it takes on, per the standard rate-and-fee vocabulary compiled in Murray Resources' recruiting and staffing industry glossary, distinct from time-to-fill, which measures how fast a fill happens rather than whether one happens at all.

Fill Rate explained
Fill rate and time-to-fill answer two different questions about the same job order. Fill rate asks whether the order got filled at all. Time-to-fill asks how long it took once it did. A firm can have a fast time-to-fill on the orders it fills and still carry a weak fill rate overall, if it is taking on requisitions it cannot realistically source for and simply walking away from the ones that do not pan out.
A low fill rate can point at a few different root causes: job orders that are poorly qualified or unrealistic on rate versus role, a candidate pool that does not match what the client actually needs, or a firm spreading itself across too many open orders at once to work any of them properly. Diagnosing which cause is actually driving a weak fill rate matters, since the fix for each is different.
Fill rate is also a real trust signal to a client evaluating whether to keep sending an agency job orders at all. A client watching a vendor consistently fail to fill the roles it accepts has a concrete, measurable reason to route future orders to a Tier 1 vendor or a different firm entirely instead.
Why it matters when you're buying
A prospect's honest fill rate, not just their pitch, tells you how disciplined their intake and qualification process actually is before a job order gets accepted. It is a fair, specific question to ask in a discovery conversation, not an accusation.
