A Small Business Guide to Timesheets

Updated August 11, 2026 · 5 min read

A timesheet is a simple record of hours worked over a period — usually a week — but it does a lot of quiet work. It is how hourly employees get paid correctly, how you bill clients for time honestly, and how you learn where your team's hours actually go. Whether you have one contractor or a small crew, a clean timesheet habit prevents payroll errors and billing arguments.

What a timesheet should capture

  • Who and when. The worker's name, the week-ending date, and the project or client the time is for.
  • Hours per day. A row per day with the hours worked, ideally split into regular and overtime.
  • A weekly total. The sum of the daily hours, calculated for you so nobody fat-fingers the math.
  • Approval. A manager or client signature confirming the hours are accurate.

Regular vs. overtime hours

Separating regular and overtime hours matters because overtime is usually paid at a higher rate and, in many jurisdictions, is legally required past a certain threshold (often 40 hours a week). Tracking them separately from the start means payroll is right the first time and you have documentation if anyone ever questions a paycheck.

Tips for timesheets people actually fill in

  • Keep it short. A weekly grid people can complete in two minutes beats a detailed system nobody updates.
  • Fill it in daily, not on Friday. Reconstructing a week from memory is how errors creep in.
  • Get it approved promptly. A signature while the week is fresh is worth more than one added weeks later.
  • Keep copies. Timesheets are records you may need for payroll audits, client disputes, or tax purposes.

From hours to a bill

For client work, an approved timesheet is the evidence behind your invoice. Attach or reference it so clients can see exactly what they are paying for — it makes bills easier to approve and harder to dispute.
