TL;DR

A timesheet is a record of hours worked by an individual, used as the basis for billing clients and paying workers in temporary and contract staffing. Timesheets are the operational heartbeat of the contingent workforce: no approved timesheet, no invoice, no paycheck. In modern staffing, they are almost always digital, but the disputes they generate are entirely analog.

What a Timesheet Actually Does

A timesheet does two things simultaneously: it authorises payment to the worker and authorises billing to the client. The moment a timesheet is approved, it creates a financial obligation in both directions. The agency pays the worker for the hours recorded. The agency invoices the client for the same hours at the bill rate. The difference is the margin.

In temporary staffing, timesheets are typically weekly. The worker records hours worked each day. The client approves or disputes the timesheet. The agency processes payroll and invoices based on approved timesheets. In high-volume environments with hundreds of temps, this cycle runs like clockwork every Friday or Monday.

The specific information a timesheet captures varies by arrangement:

• Basic: start time, end time, break duration, total hours per day
• Detailed: job codes, cost centres, project codes, expenses
• Compliance-driven: meal break attestation, overtime classification (especially in California, where missing a 30-minute meal break triggers premium pay)

Timesheets are also the primary audit trail for employment law purposes. Hours records are required under the UK Working Time Regulations for most workers. In the US, the Fair Labor Standards Act requires employers to keep accurate records of hours worked. Timesheets are the evidence.

Why It Matters for Recruitment

Timesheet disputes are one of the most common and damaging operational failures in temporary staffing. A worker submits 40 hours. The client approves 35. The worker insists the other five hours were worked. The recruiter is in the middle, trying to get a timesheet approved so they can run payroll, while the client manager is unavailable and the deadline is Friday at noon.

For agencies, late or disputed timesheets directly affect cash flow. If timesheets are not approved on time, the agency still often has to pay the worker (especially for PAYE temps in the UK, where payment is tied to hours worked, not client approval), but cannot invoice until approval is received. Agencies with poor timesheet compliance infrastructure carry significant working capital risk on large temp books.

For in-house recruitment and procurement teams managing contingent labour, timesheet processes define the accuracy of workforce cost reporting. An unreliable timesheet process means finance cannot trust the contractor cost figures. It also creates liability: if a temp was working unauthorised overtime and there is no timesheet record, the client may still owe the hours.

For compliance purposes, timesheet records are the first thing a labour authority requests when investigating a wage claim. Whether a worker was paid for all hours, received required breaks, or was misclassified often comes down to what the timesheet shows.

In Practice

A logistics company has 60 warehouse temps through a staffing agency. The agency runs a digital timesheet system where workers clock in and out via a mobile app and supervisors approve weekly timesheets before noon on Monday. One week, a supervisor misses the approval deadline. The agency cannot process payroll for 12 temps until Tuesday. Those temps are owed same-day payment under their contracts. The agency covers the payment from its own cash, invoices the client Tuesday, and flags the approval failure as a performance issue. After three similar incidents, the agency escalates to the client's procurement team.
