Buddy punching is when one employee clocks in or out on behalf of another who isn't actually there. It sounds harmless — "cover for me, I'll be 20 minutes late" — but across a crew it quietly drains payroll.
What does it cost?
Studies estimate buddy punching costs U.S. employers billions a year, and that time theft can inflate payroll by around 2–5%. For a 40-person crew, even a few padded hours a week adds up to thousands of dollars a year — straight off your margin.
How it happens
- Paper timesheets filled in after the fact.
- Shared PINs or badges anyone can punch.
- Time-tracking apps with no identity check — anyone with the login can clock in from anywhere.
5 ways to stop buddy punching
- Facial recognition clock-in. The worker's face is the password — nobody can punch for a no-show.
- GPS geofencing. Clock-ins only count inside the job-site zone, so "I was there" becomes provable.
- Photo or selfie verification at punch time as a fallback.
- Manager alerts for missed or late clock-ins so problems surface fast.
- A clear written policy employees sign — paired with the tech above.
The simplest fix
Combine face scan + GPS and the problem basically disappears: the right person, at the right place, at the right time — with proof. That's exactly what PosupClock does, at a flat price with no per-employee fees.
