What it is
Time-to-fill is the elapsed time from the moment a job order opens, the point at which a client formally authorises a vacancy to be worked, to the moment the placed candidate actually starts in the role. It is measured in calendar days, tracked per role, and rolled up per desk or per agency to show how quickly vacancies are being turned into working hires. Because the clock runs all the way to a start date rather than stopping at an offer or an acceptance, it captures the full commercial cycle a client actually experiences.
It is often confused with time-to-hire, which some organisations define more narrowly, from application or first candidate contact to offer accepted. The two overlap but answer different questions: time-to-hire is a hiring-process metric, time-to-fill is a business metric that also captures how quickly the vacancy was opened up to the market and how quickly the successful candidate could actually join. There is no universal benchmark figure; it varies hugely by role seniority, market and sector, so agencies track it against their own historical baseline and the client's own expectations, not a fixed number.
Time-to-fill is rarely lost in the interview room. It is lost in the weeks before a shortlist ever reaches the client.
Why it matters
Time-to-fill is one of the few numbers a client tracks without needing to be told to. It shows up in every PSL and MSP review, gets compared across the agencies on a panel, and is often the single metric that decides whether the next job order comes back to you or goes somewhere else. A consistently fast time-to-fill signals a desk that is organised, has real market coverage and does not waste a client's attention; a consistently slow one erodes trust even when the eventual hire is a good one.
Most of the delay in a slow fill sits at the start, not the end. Interviews and offer negotiations take roughly the same number of days everywhere; what varies is how long it takes to get the brief right, build a first shortlist and land a decision-maker's attention in the first place. A desk that is already in conversation with an account before the vacancy is even raised, or that already has warm candidates on file, starts the clock with weeks of runway competitors do not have.
How boilr handles it
boilr does not run interviews or negotiate offers, but it compresses everything that happens before a shortlist lands on a client's desk. Signal-led BD gets a consultant into the conversation while a vacancy is still forming, often before a job order is formally raised, so the time-to-fill clock effectively starts with a head start. Talent pooling keeps qualified, warm candidates on file in the Company Brain, so the first shortlist for a matching brief can go out in hours rather than the days a cold search takes.
Every job order boilr helps win is tracked as a live stage in the BD pipeline, so a consultant or manager can see at a glance how long a mandate has been open and where it is slipping, rather than discovering a slow fill only when the client raises it. Silver medalists and past search history are resurfaced automatically against new briefs, giving the desk a warm starting shortlist for roles that resemble ones it has filled before. A consultant still runs the search and closes the placement; boilr just shortens the distance to the starting line.
