Because the inputs arrive from everywhere else. An attendance sheet from each site, a leave spreadsheet, an overtime email, a list of salary changes that were approved somewhere. Every one is a transcription, and every transcription is a chance to be wrong.
The cost is not just the time. It is that a dispute cannot be settled, because nothing recorded what was true before the correction.
Attendance comes from check-in and check-out, leave from the approved requests, overtime and premiums from the roster. Compensation revisions are dated records, so a mid-month change applies from the right day rather than from whenever it was noticed.
Regularisation is a request with an approver and a reason, not an unattributed edit.
It does not file your statutory returns for you or interpret your obligations. It produces the figures and holds the evidence; submission and interpretation stay with you and your accountant.
And it will not correct a bad approval. It will show you exactly who approved it and when.
Every value on a payslip traces back to a record with an actor and a timestamp, and the previous value is kept. A query about overtime takes a minute rather than a morning.
Loans, advances and reimbursements are on the same record, so nothing is carried between months in a side sheet.
The roster and the clock, not a transcribed sheet.
Yes — compensation revisions are dated and apply from the right day.
Yes, with previous values, and administrators cannot edit it.
Half an hour on your own numbers is usually enough to say whether Nest is the right place to start.
