Three things: paying people correctly, meeting statutory record-keeping obligations, and knowing whether cover was adequate.
Only the first is usually designed for, which is why attendance systems produce a monthly total and cannot answer a question about a specific Tuesday six months ago.
For desk workers, a clock is largely ceremonial and an exception-based approach — record absence, assume presence — is less friction for the same result.
For shift, field and shop-floor work, capture has to happen where the work is, from a phone or a terminal. Attendance transcribed from paper in an office is the single largest source of payroll error in shift operations.
Usually not. Exception-based recording gives the same result with less friction.
As a request with a reason and an approver, never as a silent edit.
It should. Every transcription between the two is an opportunity for error and dispute.
Half an hour with your own data usually saves reading three of these. The guides will still be here afterwards.
