Attendance Management Software: How It Works and What It Calculates

Attendance management software is the link between the fingerprint device on the wall and the payroll at month end. The device records that an employee walked past at 08:25. It does not know whether that was late, or whether the employee was on leave yesterday or absent. A time and attendance system knows each employee’s shift, leave and excuses, so it can answer, and it produces the monthly report salaries are calculated from.

This article explains what the software does with a punch and what it calculates, with a worked example of one employee’s week. If you are still comparing products, see the guide to choosing a time attendance system.

A biometric device is not attendance software

Biometric attendance devices, whether fingerprint, face or card, produce a list of punches: an employee number and a time. To turn that list into attendance management you need three things the device does not know:

• The employee’s shift on that day: when work starts and ends.
• What has been approved: leave, an excuse for lateness, or overtime.
• The company calendar: weekly rest days and public holidays.

The software combines these with the punches and gives every employee one clear status for every day.

How a punch becomes a status

For each day the software first asks which shift applies, then compares the punches with it:

• Present: arrived on time and completed the shift.
• Late: arrived after the shift started; lateness is counted in minutes.
• Absent: a working day with no punch, not covered by leave or a holiday.
• Overtime: time worked beyond the shift, recorded and approved.

That is why the right shift matters. A night shift from 22:00 to 06:00 belongs to the day it started, and a split shift has more than one in and one out. Evaluate a day against the wrong shift and a normal day turns into lateness or absence.

Not every day without a punch is an absence

The most common mistake in employee absence tracking is treating every day without a punch as absent. That day could be:

• Approved leave: annual, sick or another type, paid or unpaid according to its type.
• A public holiday: defined once for all employees.
• A rest day: the weekly rest day in the employee’s schedule.
• A real absence: when none of the above applies.

Good attendance software does not count the first three as absence, so HR does not have to fix the report by hand.

Lateness, excuses and overtime

Not all lateness should be deducted. An employee who left for a medical appointment with the manager’s agreement has an approved excuse: the minutes show in the report but are not deducted. The excuse must be recorded and approved in the system, not kept as a message on a phone.

Overtime is similar. Staying late does not automatically mean hours are owed; overtime is recorded and approved, then reaches payroll. Working-hour limits and overtime pay under the Saudi Labour Law are covered in our article on working hours and overtime.

Worked example: one employee’s week

Shift 08:00 to 16:00, Sunday to Thursday; Friday and Saturday are rest days:

The week in summary: five working days, three attended, one day of leave that is not absence, and one absence. Only 25 minutes of lateness are deductible, because the other 70 are excused. Approved overtime is two and a half hours.

The monthly report adds these up across the month: days present, absent and on leave, with total lateness and overtime, for each employee.

The reports HR and the accountant need

• Daily attendance report: who is in, late or absent today.
• Employee attendance over a period: to review one person’s record or answer a query.
• Monthly attendance report: the page the accountant receives at month end.
• Group attendance report: a whole team on one page.
• Absence report: who is nearing the warning threshold, under rules you set.
• Overtime and excuse reports: the items that change pay.

What matters most is that every report comes from the same record, so the daily report, the monthly report and the salary agree.

From attendance to payroll

When payroll is calculated from attendance inside the same system, absent days, unexcused lateness, approved overtime and unpaid leave reach the salary without a spreadsheet in between, and every deduction can be traced back to its source.

Common mistakes when tracking attendance in Excel

• Copying punches by hand from each device or branch into one file.
• Splitting night shifts across two days, so the employee shows late on one and absent on the other.
• Recording leave as absence because the paper request never reached whoever keeps the sheet.
• Formulas that change from month to month with no one knowing who changed them.
• Edits with no trace: a corrected clock-in time leaves no sign it was changed.

How IdaraSuite does it

• Biometric devices from ZKTeco, Hikvision and Suprema send punches directly over the internet, with no branch PC and no static IP. If the connection drops, the device keeps the punches and sends them when it returns.
• Each day is evaluated against the employee’s actual shift: fixed, night shifts that cross midnight, or more than one period, with rosters.
• Overtime and excuses are requested and approved in the system; approved leave, public holidays and rest days are not counted as absence.
• Daily, monthly and group attendance reports and an absence report, filtered by branch, department and job title.
• Payroll is calculated from actual attendance in the same system.
