How to use it — and why it matters

Labour is the second big leak. Attendance recorded on paper muster rolls is easy to inflate, and sub-contractor bills are hard to check against agreed rates and real headcount. This calculator estimates what that leakage costs against your monthly labour spend — before real attendance and rate-checked billing close it.

What drives labour leakage?

Ghost workers on the muster roll, over-stated attendance, and sub-contractor bills claiming more labour or higher rates than agreed. 6% is a common working figure for manual muster rolls.

How does verified attendance help?

When attendance is captured at site (and, soon, geofenced with a selfie check-in), the muster roll can't be padded — and sub-con bills are checked against real, recorded headcount and agreed rates.
