The Real Cost of Manual Attendance in a Factory

A muster register, a few minutes of adjustment per worker, and a payroll leaking lakhs a year. How one plant made factory attendance a non-issue.

A packaging manufacturer in Noida, ₹95 crore, three shifts, 340 people on site on a normal day. About 120 of those come through two labour contractors, and that is where payroll day used to turn into an argument. Biometric had been in for years and covered the permanent staff properly. What it did not cover was whether the contractor's monthly bill matched the people who had actually been on the floor.

When they finally added it up, the gap between hours worked and hours billed came to a serious number every month. Not from fraud, mostly. From rounding, from a headcount agreed verbally at the gate, from overtime nobody could verify, from plain honest confusion.

What does manual attendance cost a factory?

Most of the leak sits in contract labour, where a muster register cannot prove who was actually on the floor. One 95 crore plant running 340 people across three shifts found its contractor bills and real hours worked diverged by lakhs every month, with no fraud involved. Biometric covering only permanent staff leaves that gap wide open.

Why a register can't keep up

A paper muster on a large, shift-based floor is asking for trouble. Entries get written up from memory at the end of the day. A friend signs in for a colleague who's late. Overtime gets approved verbally and recorded vaguely. None of it is dramatic, and all of it leaks.

On a 200-person floor, a few unverifiable minutes per worker per day adds up to a full salary every month.

What changed it

Biometric punch-in at the gate, wired straight to payroll. Hours were now captured at the source, overtime needed a real approval against real clock data, and the monthly argument had nothing left to argue about. The register stopped being a negotiation. Tying attendance to payroll is one of the things Facto handles end to end.

Biometric + digital payroll₹0.5L

The unexpected benefit

The workers liked it more than management expected. Accurate clock data meant the people who genuinely worked late finally got paid for every minute, no debate. Fairness cut both ways, and trust on the floor went up rather than down.

If you want to check what one of those late shifts should come to, our sister product for smaller teams has an overtime calculator that works it out at the legal double rate, on the same payroll engine Facto uses.
