Time and attendance software: methods, overtime, payroll

Time and attendance software records when employees start and finish work, calculates the hours actually worked and sends normal hours, overtime, lateness and absences to payroll. Employees can clock in with a badge, biometrics, a QR code, GPS or a smartphone app: each method has its strengths, costs and legal constraints. This guide explains what time tracking (known as pointage in French-speaking Africa) is, compares the methods, shows the link with payroll and personal data rules, and gives you a grid to choose a solution. Updated on 3 November 2026.

In brief

• Clock-in records are the proof of working time: they drive overtime pay and deductions.
• Five methods coexist: badge, biometrics, QR code, GPS and mobile app. The right choice depends on where people work, not on the latest technology.
• The value of time and attendance software shows at month end: approved hours that reach payroll without re-keying.
• Biometrics is the most regulated method: prior authorisation from the data protection authority in several countries, including Senegal, Ivory Coast and Morocco.

What is time and attendance tracking?

Time and attendance tracking is the time-stamped record of an employee’s presence: when they start, take a break, resume and finish their day. For a long time it was done on a paper sign-in sheet or with a punch-card clock. Today the word covers both the act of clocking in and the system that collects the data and turns it into payable hours.

Tracking serves three distinct needs that should not be confused:

• Proof of actual working time, when an employee claims overtime or when the labour inspectorate checks.
• Accurate pay: normal hours, overtime at the right premium, night work, lateness and unjustified absences.
• Management: absenteeism rate, recurring lateness by site, overtime cost by team.

Time clock, time and attendance software, time management: what is the difference?

The time clock is the hardware (kiosk, badge reader, biometric terminal). Time and attendance software is the program that receives clock-ins, applies schedules and rules, and produces timesheets. Time and absence management goes further: rosters, leave, special leave, manager approval and export to payroll. Modern time and attendance software usually covers all three levels, and the employee’s smartphone can replace the time clock.

Clock-in methods compared

There is no single best method. A head office, a factory, a construction site and a travelling sales force face different constraints. Here are the five methods found in companies across French-speaking Africa.

Badge (RFID or magnetic card)

The employee holds a card to a reader at the entrance. It is simple, fast and well accepted. The known weakness: a colleague can badge in for someone else. A badge also needs a reader at every entry point, powered and often networked, which suits fixed sites but not dispersed teams.

Biometrics (fingerprint, face)

Biometrics prevents buddy punching, since the data is tied to the employee’s body. It is also the most sensitive method legally, because biometric data is a special category of personal data. In Senegal, processing it requires authorisation from the CDP, the data protection commission (Law No. 2008-12). In Ivory Coast, the regulator ARTCI stated in June 2024 that biometrics without authorisation is prohibited and found it disproportionate for simple attendance control. In Morocco, the CNDP requires an authorisation request and accepts biometrics for access only where alternatives are insufficient. Check that you will be allowed to use biometric terminals before buying them.

QR code

A kiosk or screen displays a QR code that the employee scans with their phone. When the code is dynamic (it changes regularly), a photo of the code sent by message cannot be used to clock in remotely. QR codes cost little, store no biometric data and work well in offices, branches and factories.

GPS and geofencing

The employee clocks in from their phone and the time and attendance software records their location at that moment. With geofencing, a clock-in is accepted only inside a perimeter defined around the site. This suits construction sites, sales agents, maintenance crews and security guards. Location should be captured only at clock-in: tracking an employee continuously is surveillance that must be justified and proportionate.

Offline mobile app

The mobile app often combines QR code and GPS. The decisive point in Africa is offline operation: the clock-in is time-stamped and stored on the phone, then synchronised as soon as the network returns. Without it, an agent in a dead zone cannot clock in, and you are back to paper.

In practice, one company often combines two methods: QR code at head office, GPS on sites. For field roles, our guide on digitalising field operations details the organisation to plan.

Overtime: from time and attendance software to payroll

Clock-in data is only worth something if it leads to accurate pay. This is where a simple hour recorder differs from time and attendance software connected to payroll.

What the software must calculate

• Normal hours, against the statutory or collective-agreement working week: 40 hours in Senegal, Ivory Coast, Benin and Cameroon (non-agricultural sector), 44 hours in Morocco, 45 hours in the DRC.
• Overtime, by band, at the right premium. Bands and rates vary from one country to another and sometimes from one collective agreement to another.
• Night work, weekly rest day and public holidays, which carry higher premiums.
• Lateness and unjustified absences, deducted only after HR approval.
• Caps: in Benin, for example, the Labour Code sets a ceiling of 240 overtime hours per calendar year.

Worked example (illustration)

Take a technician in Senegal paid 1,000 FCFA an hour (illustrative amount) who works 50 hours in a week, i.e. 10 overtime hours. The 2019 national inter-professional collective agreement (CCNI, art. 49) adds 15% to the first 8 overtime hours and 40% to the following ones:

• 8 hours at 1,150 FCFA = 9,200 FCFA;
• 2 hours at 1,400 FCFA = 2,800 FCFA;
• total overtime for the week: 12,000 FCFA, instead of 10,000 FCFA without premiums.

Across 150 employees and four weeks, a repeated band error quickly becomes a significant gap and a back-pay risk. Time and attendance software should therefore apply the bands automatically, then let the manager approve before the data goes to payroll.

The ideal flow

1. The employee clocks in (QR code, GPS, badge).
2. The software applies the employee’s schedule and calculates variances.
3. The manager approves or corrects the timesheet, with a reason.
4. HR closes the period.
5. The variables (overtime by rate, night work, lateness, absences) reach payroll with no re-keying.

This is how Socium Time, Socium’s time and attendance software works: clock-in by dynamic QR code or GPS with geofencing, a mobile app that works offline, timesheets approved by managers and passed straight to payroll. Leave follows the same flow; see our guide to leave management.

Time tracking and personal data

Time and attendance software processes personal data: identity, working hours, sometimes GPS location or fingerprints. Almost every French-speaking African country has a data protection law and authority, and the principles are similar.

• Purpose: tracking measures working time and supports pay; it is not for monitoring private life.
• Proportionality: in Senegal, the 2026 Labour Code (art. 23 and 24) allows monitoring devices, including geolocation, badges and biometrics, only if justified by the task and proportionate to the aim.
• Information for employees and staff representatives before go-live.
• Formalities with the authority: declaration or authorisation depending on the processing, and authorisation for biometrics in most cases.
• Security and limited retention: access restricted to HR and the managers concerned.

For details, read our article on HR data protection in Senegal, and the website of the CDP (Commission de protection des données personnelles).

Time and attendance software by country

Working-time rules, overtime premiums and data protection change from one country to another. Each country guide sets out its own framework.

Senegal’s 2026 Labour Code leaves overtime premium rates and the annual overtime quota to collective agreements or, failing that, to a decree (art. 244); our article on the Senegal Labour Code 2026 covers the changes.

How to choose time and attendance software

Before comparing vendors, describe your sites, schedules and payroll flow. Then use this grid.

Pricing models

Vendors generally charge in one of three ways: a subscription per employee per month (cloud software), a licence with annual maintenance (on-premise software), or a hardware purchase (time clocks, kiosks) plus software. Compare the total cost over three years: hardware, installation, cards or phones, maintenance, training and HR time saved. A mobile solution often avoids buying time clocks for every site.

Mistakes to avoid

• Buying biometric terminals before checking the formalities with the data protection authority.
• Choosing time and attendance software that does not talk to payroll: you re-key, make errors and lose the benefit.
• Setting a single schedule for everyone when teams work in shifts.
• Going live without informing employees or training managers to approve timesheets.
• Forgetting field teams, who often work the most overtime.

Rolling out time and attendance software in 5 steps

1. Map sites, headcount, schedules, field teams and network coverage.
2. Choose methods site by site and complete the personal data formalities.
3. Configure schedules, cycles, overtime bands, public holidays and the approval flow.
4. Test on a pilot site for a full payroll cycle, alongside the old system.
5. Roll out and track indicators: missing clock-ins, corrections per manager, overtime by team, time to close the period.

Frequently asked questions about time and attendance software

What is time and attendance software?

It is a program that records employees’ start and finish times, applies their schedules, calculates normal hours and overtime, and passes the results to payroll.

What is the difference between a time clock and time and attendance software?

The time clock is the hardware that captures the clock-in. The software processes the data. With a mobile app, the employee’s phone replaces the time clock.

Is biometric clock-in allowed?

It is not banned as such, but it is tightly regulated: prior authorisation from the data protection authority in Senegal, Morocco and Ivory Coast, where ARTCI found it disproportionate for simple attendance control.

Can employees clock in without an internet connection?

Yes, if the app stores the time-stamped clock-in on the phone and synchronises it when the network returns. Test it in the demo by switching the network off.

Can an employer geolocate employees for clock-in?

Yes, to record the location at the moment of clock-in, provided employees are informed and the system is proportionate. Continuous location tracking is much harder to justify.

How does time tracking calculate overtime?

It compares the time recorded with the reference working week (for example 40 hours), splits the excess into bands and applies the premiums of the country and the collective agreement.

Is time and attendance software suitable for an SME?

Yes. A cloud solution with a mobile app needs no heavy hardware and is priced per employee, which suits teams of a few dozen people.

How long does it take to roll out?

Allow at least one full payroll cycle of testing on a pilot site before rolling out further; the total time depends on the number of sites and schedules.

Key takeaways

• Clock-in records prove working time and underpin accurate pay.
• Choose the method by location: QR code in the office, GPS in the field, offline mobile in low-coverage areas.
• Biometrics requires authorisation and must be proportionate.
• Good time and attendance software sends approved hours to payroll, with the country’s overtime premiums.
