Why integrate attendance with payroll?

It removes re-typing, reduces LOP and overtime errors, and makes salary disputes easy to resolve from one record.

Can payroll use biometric device data?

Yes, device punches can feed attendance, which payroll then uses for paid days.

How is LOP calculated?

Typically monthly salary ÷ days in the period × unpaid days, per your policy.

Can I use a custom cut-off date?

Yes, many companies run payroll from the 26th to the 25th; the cycle should be configurable.

Attendance Software and Payroll Integration Explained

Most payroll disputes start in attendance. When punches, leave and overtime live in one system and salary in another, someone re-types the numbers every month, and that is where errors enter.

What flows from attendance to payroll

Attendance data	Payroll effect
Present days	Paid days
Unpaid absence	Loss of pay (LOP) deduction
Approved leave	Paid or unpaid based on leave type
Weekly offs and holidays	Paid days as per policy
Late marks and half days	Deductions or half-day pay per rule
Overtime hours	Overtime pay, and ESI wage check
Night or shift allowance	Allowance amounts

Three ways to connect them

Manual: export attendance and type totals into payroll. Cheap but slow and error-prone.
File import: upload an attendance sheet or device export. Faster but still a monthly chore.
Built-in integration: attendance, leave and payroll share one database, so approved data flows straight into the salary run.

How it works in NexoraHRMS

Employees punch via biometric, web or mobile check-in; managers approve leave and regularisation; the payroll run reads paid days, LOP and overtime for the month, and a pre-check warns about gaps such as missing attendance. Months can be locked once approved. See attendance payroll software.
