Attendance rules that quietly break payroll
Payroll errors are usually blamed on the salary calculation. Far more often the salary maths was right and the attendance feeding it was not.
When a payroll run produces a wrong number, the salary structure gets examined first. It is usually fine.
The error is normally upstream, in how attendance was turned into payable days — and the rules that govern that are rarely written down anywhere.
The rules nobody agreed in writing
Where a shift begins and ends
Easy for a 9-to-6 office. Not for a night shift crossing midnight, where the question is which day the hours belong to. Get it wrong and one day shows absent while another shows double.
Also: how much lateness is tolerated, and does repeated lateness convert to something? Both need a stated answer, because otherwise each supervisor applies their own.
What a weekly off means when surrounded by absence
The sandwich question. If someone is absent Friday and Monday, is the Sunday paid?
There is no universal answer — it depends on your policy and what applies to your establishment. What matters is that the policy exists, is stated, and is applied identically for everyone, because this is where employees notice inconsistency fastest.
When overtime starts
After the shift, after a daily threshold, or only beyond a weekly total? Is it approved in advance or claimed after? At what rate, and does the rate differ on a weekly off or holiday?
Each is a policy decision. The system can implement any of them and cannot guess which you use.
What a half day actually is
Hours worked, or arrival before a cutoff? Does a half day plus a half day make a full day for attendance, and does it for leave? Sounds trivial and generates monthly disputes.
Who can regularise, and how far back
Biometric devices miss punches. Someone must be able to correct that.
The questions are who approves, how far back it can be done, and whether it locks once payroll processes. Without a cutoff, corrections arrive after salary is paid and every month reopens the last one.
Why this decides go-live
Payroll is judged on the first live run. If it produces a wrong figure for even a handful of people, confidence goes — and the parallel spreadsheet returns, at which point the system holds partial data and its output really is unreliable.
Nearly every one of those first-run errors traces back to an attendance rule that was assumed rather than agreed.
Settle these before configuration
- Shift definitions, including any crossing midnight, and which day hours belong to
- Grace period for late arrival, and what repeated lateness does
- Weekly off treatment when surrounded by absence
- Overtime trigger, approval route and rate, including holidays
- Half-day definition, for attendance and for leave
- Regularisation: who approves, how far back, and when it locks
- How a missing punch is treated by default before anyone corrects it
Seven decisions. An afternoon with whoever actually runs payroll, and the first live run stops being a lottery.
The one that causes the most arguments
The default for a missing punch. If the default is absent, employees chase corrections and HR spends the month processing them. If it is present, genuine absence gets paid.
Most organisations land on a middle position — flagged as an exception requiring approval, with a deadline. The important part is deciding deliberately rather than discovering the default after payroll has run.

Frequently asked questions
Because the salary structure is usually correct and the payable days feeding it are not. Shift boundaries, weekly off treatment, overtime triggers, half-day definitions and regularisation rules are rarely written down, so each supervisor applies their own interpretation and the resulting figures differ.
With a stated rule about which day the hours belong to. Without one, the same shift can show as absent on one day and doubled on another. It is a policy decision the system implements — it cannot infer which convention your organisation uses.
Whether a weekly off surrounded by absence — absent Friday and Monday, with Sunday between — is paid. There is no universal answer; it depends on your policy and what applies to your establishment. What matters is that the policy is stated and applied identically, because employees notice inconsistency here fastest.
Deliberately, not by default. If missing punches default to absent, employees chase corrections all month; if present, genuine absence gets paid. Most organisations flag them as exceptions requiring approval with a deadline — the important part is choosing rather than discovering the default after payroll runs.
Seven things: shift definitions including those crossing midnight, grace period and what repeated lateness does, weekly off treatment during absence, overtime trigger and rate including holidays, half-day definition for attendance and leave, regularisation authority and cutoff, and the default treatment of a missing punch.
