Time-to-fill — the amount of time a third-party supplier takes to fill a position — is a closely watched ratio for contingent workforce managers, and it varies by type of business, according to research from SIA.
For professional temp staffing, time-to-fill as measured by when a candidate accepts the offer typically ranges from four to 14 days, with a median of nine days. As measured by when a candidate starts on the job, the typical range is 10 to 24 days, with a median of 14 days. The midrange fill rate for professional temp staffing is 24% to 75%, with a median of 40%.
Meanwhile, for commercial staffing roles, both time-to-fill based on when a candidate accepts an offer and for time-to-fill based on when a candidate starts a job, the midrange was two-to-three days to seven-to-eight days. The reported median was four-to-five days. The midrange for fill rates was 50% to 80%, with a median of 65%.
