Professional staffing billable hours measure the amount of contract labor delivered to customers during a period.

Kforce reported 3.926M total Flex hours in the second quarter of 2026, up 3.7% from 3.787M a year earlier. Robert Half moved the other direction: contract talent hours worked fell 2.8% year over year in the same quarter.

Hours are the cleanest volume signal in hourly staffing

Revenue can rise because the company billed more hours, charged more per hour, or both. Hours strip away most of the price effect and show how much work was actually delivered.

Kforce explicitly decomposes revenue changes into hours billed, bill rate, and billable expenses. That makes hours the volume leg of the revenue volume-rate bridge.

Calendar days can distort the comparison

A quarter with more working days can create more billable capacity even if demand per day is unchanged. Investors comparing periods should therefore also inspect the billing-day adjustment.

Hours also need to be interpreted with the average bill rate. Stronger hours with falling rates can produce very different economics from stronger hours with stable pricing.

Where this concept fits

Contract staffing volume, rate, and calendarCurrent relationship
Billable hours measure delivered labor volume, average bill rate captures pricing and assignment mix, billing-day adjustment normalizes the calendar, and the volume-rate bridge explains how those pieces combine into contract revenue growth.

Contract staffing spread and gross margin
The pay-bill spread captures the gap between customer billing and worker pay, while contract gross margin incorporates payroll taxes, benefits, reimbursable expenses, conversion revenue, and other direct-cost effects around that spread.

Permanent placement and contract-to-hire economics
Permanent-placement revenue is driven by successful placement count and average fee, while conversion revenue captures a separate contract-to-hire path that can contribute high-margin fee revenue without adding contract hours.
