The verdict in three sentences
A site slips for lack of reliable field tracking and exact attendance, not from bad luck. Daily photo reports and geolocated clock-ins cut schedule overrun by 15 to 25 % and eliminate ghost payroll that weighs 5 to 12 % of the wage bill. For 2,500,000 to 5,500,000 FCFA, the tool pays for itself on a single mid-size site.
The price of vagueness on a site
Without tracking, the project manager discovers the delay too late and pays for hours never worked. The app turns the field into data: photographed progress, timestamped and geolocated clock-ins, traced incidents.
| Indicator | Without app | With the app (2026) |
|---|---|---|
| Average schedule overrun | 20-40 % | 15-30 % (-15-25 % relative) |
| Ghost attendance / payroll | 5-12 % | near 0 |
| Daily report time | 30-60 min | < 5 min (photo) |
| Delay detection | end of phase | daily |
| Worker pay disputes | frequent | timestamped records |
| Owner visibility | occasional | real time |
What the app costs
Budget depends on the number of sites tracked, biometric or GPS clock-in and payroll integration. 2026 ranges.
| Item | 2026 range (FCFA) | Detail |
|---|---|---|
| Tracking + photo report app | 2,500,000 - 3,800,000 | progress, incidents |
| Geolocated clock-in module | +600,000 - 1,200,000 | GPS, timestamp |
| Payroll integration | +400,000 - 700,000 | hours export |
| Site-manager training | 200,000 - 400,000 | field |
| Annual maintenance | 350,000 - 700,000/yr | support |
| Site payroll | 2 - 20 M/month | by size |
Mini case study
Ibrahim runs a site in Abidjan with a payroll of 8,000,000 FCFA/month over 10 months, i.e. 80,000,000 FCFA. He suffered 8 % ghost attendance, i.e. 6,400,000 FCFA gone. With geolocated clock-in, that item falls to 1 %, saving 5,600,000 FCFA. In parallel, cutting the delay by 3 weeks avoids about 4,000,000 FCFA of penalties and fixed costs. The app at 4,000,000 FCFA pays back on the very first site.

Does geolocated clock-in work without network?
Yes, the clock-in records locally with position and timestamp, then syncs. A worker can only clock in within the site perimeter, which eliminates ghost payroll.
How long does the daily report take?
Under 5 minutes: the foreman takes photos, ticks completed tasks and notes incidents. The owner sees progress in real time.
Does the app integrate with payroll?
Yes, clocked hours export to your payroll system, removing re-entry and disputes that often amount to several working days a month.
Can several sites be tracked at once?
Yes, a consolidated dashboard shows progress, payroll and delay alerts for all active sites.
What does the end client see?
A read-only access shows photographed progress and the schedule, cutting meetings and reassuring against the sector's usual 20-40 % overruns.
