The verdict in three sentences
A mining contractor still clocking in on paper overpays on average 3 to 5% of its payroll and struggles to prove HSE compliance to the majors. Custom software covering offline biometric timekeeping, work permits, incidents and certifications costs 20 to 45 million FCFA excl. VAT (about €30,500 to €68,600) for 500 employees and 3 sites. The constraint that drives the architecture is connectivity: everything must work without a network, syncing over satellite or 4G when available.
Essential modules and their cost
On a gold mine in Mali, Burkina Faso, Guinea or the Kédougou region of Senegal, the client demands proof: who was on site, with which certification, under which work permit, and which incidents were reported. The software must produce that proof within minutes during an audit.
| Module | Key function | 2026 range (FCFA excl. VAT) | Estimated effort |
|---|---|---|---|
| Offline biometric timekeeping | Fingerprint or face, local timestamp, anti-fraud | 4,000,000 to 8,000,000 | 25 to 35 days |
| Work permits | Work at height, hot work, confined space, lockout | 3,500,000 to 7,000,000 | 20 to 30 days |
| Incident reporting | Photo, geolocation, severity, action plan | 2,500,000 to 5,000,000 | 15 to 20 days |
| Certifications and training | Expiry dates, alerts 30 days ahead, access blocking | 2,000,000 to 4,500,000 | 12 to 18 days |
| Satellite or 4G sync | Queueing, compression, resume after outage | 3,000,000 to 6,000,000 | 18 to 25 days |
| HSE and payroll dashboards | TRIR, LTIFR, hours exported to payroll | 2,500,000 to 6,000,000 | 15 to 22 days |
| Field mobile apps | Rugged Android, full offline mode | 2,500,000 to 8,500,000 | 20 to 35 days |
Hardware, connectivity and recurring costs
Software is only part of the budget. Biometric terminals must withstand dust (IP65 rating minimum) and 45 °C heat. On a remote site, the satellite link is often shared with operations: the volume sent must stay small.
| Item (2026 order of magnitude) | Quantity for 3 sites | Unit cost FCFA | Total FCFA |
|---|---|---|---|
| IP65 biometric terminal with battery | 9 | 450,000 to 900,000 | 4,050,000 to 8,100,000 |
| Rugged Android tablet for HSE supervisors | 15 | 250,000 to 500,000 | 3,750,000 to 7,500,000 |
| Local site server (mini PC, UPS) | 3 | 600,000 to 1,200,000 | 1,800,000 to 3,600,000 |
| Shared satellite plan (software data) | 3 sites | 60,000 to 150,000 per month | 2,160,000 to 5,400,000 per year |
| Cloud hosting and backups | 1 | 80,000 to 200,000 per month | 960,000 to 2,400,000 per year |
| Ongoing maintenance | 1 | 400,000 to 900,000 per month | 4,800,000 to 10,800,000 per year |
The architecture that works: each site has a small local server that receives clock-ins and forms from tablets over Wi-Fi, even with no Internet. That server sends compressed packets of a few megabytes per day to headquarters whenever the link is up. If the link drops for three days, nothing is lost.
A 4 to 6 month timeline
Month 1: scoping with the HSE manager, the payroll manager and a site lead, gathering the client's requirements (report formats, indicators). Months 2 and 3: timekeeping, certifications and sync, pilot on the most accessible site. Month 4: work permits and incidents. Months 5 and 6: rollout to the two other sites, biometric enrolment of the 500 employees (allow 5 minutes per person, about 42 hours), training and adjustments.
Watch-outs: biometric data is personal data governed by Law 2008-12 in Senegal, Law 2013-015 in Mali and regional equivalents. A filing with the data protection authority (CDP in Senegal, APDP in Mali) is required before enrolment.
Mini case study
Ibrahim, managing director of a mining services company based in Bamako, employs 500 people on 3 sites near Sadiola and Kéniéba. His payroll reaches 210 million FCFA per month. Paper timesheets generate ghost hours and errors estimated at 3%, i.e. 6.3 million FCFA per month.

He invests 34 million FCFA excl. VAT in software, 14 million FCFA in hardware and about 12 million FCFA per year in recurring costs. If biometric timekeeping brings the gap down to 0.5%, he saves 5.25 million FCFA per month, i.e. 63 million FCFA per year. The project pays back in under 11 months, not counting the commercial value of a spotless HSE record when renewing his contract with the major.
FAQ
How much does HSE and timekeeping software cost for a mining contractor?
For 500 employees and 3 sites, allow 20 to 45 million FCFA excl. VAT for development, plus 8 to 18 million FCFA in hardware. Recurring costs range from 8 to 18 million FCFA per year depending on the maintenance level.
Does timekeeping work without Internet?
Yes, that is the baseline requirement. Terminals store several weeks of clock-ins locally, and the site server syncs as soon as satellite or 4G responds, with a volume of a few megabytes per day.
Can the software match the client's required report formats?
Yes. TRIR, LTIFR and monthly reports are configured to the major's template during scoping. An audit report is then generated in under 5 minutes.
Is an authorisation needed for biometrics?
Yes. In Senegal, the CDP must be notified before any biometric processing, and in Mali the APDP. The filing usually takes 1 to 3 months, so it should start in the first month of the project.
Why not buy an international HSE software package?
International solutions often cost USD 15 to 40 per user per month, i.e. 4.5 to 12 million FCFA per month for 500 people, and handle prolonged offline use poorly. Custom software becomes cheaper from the second year.
