The verdict in three sentences
A construction site tracking app digitises three money-leaking areas: worker attendance, material stock and progress reporting. Typical 2026 gains: a material theft reduction of around 20 % and 10 hours per week saved on manual oversight. Development sits between 2 and 5 M FCFA, with worker pay directly in mobile money.
What a site tracking app costs
Budget depends on GPS attendance, stock management and photo reporting. Here are 2026 orders of magnitude for the African construction market.
| Level | Features | Timeline | Cost (FCFA) |
|---|---|---|---|
| Attendance only | GPS attendance, presence sheet | 4-6 wks | 2 000 000 - 2 800 000 |
| Standard | + material stock, photo reporting | 8-12 wks | 3 000 000 - 4 000 000 |
| Advanced | + mobile money pay, multi-site dashboard | 14-18 wks | 4 200 000 - 5 000 000 |
| Annual maintenance | Hosting, support, updates | - | 800 000 - 1 500 000 |
Timestamped photo reporting is often the purchase trigger: it gives the business owner visual proof of progress without travelling to each site.
Where the app saves money
Let's compare before/after losses on an average site.
| Item | Without app | With app | Monthly gain |
|---|---|---|---|
| Material theft/loss (3 M/month budget) | ~15 % (450 000) | ~5 % (150 000) | 300 000 FCFA |
| Ghost hours (30 workers) | ~8 % of payroll | ~2 % | 180 000 FCFA |
| Manager oversight time | 10 h/wk | 2 h/wk | 8 h x 4 = 32 h |
| Worker pay disputes | frequent | GPS trace | fewer conflicts |
On this typical site, the app saves about 480 000 FCFA/month in direct losses, not counting recovered management time. A 4 M FCFA budget pays for itself in about 8 to 9 months.
Mini case study
Ibrahima runs a construction company in Dakar with 3 sites and 30 workers in total. Before the app, he lost about 15 % of his 3 000 000 FCFA/month material budget (i.e. 450 000 FCFA) and paid for hours not worked. After deployment, theft drops to 5 % (150 000 FCFA), a gain of 300 000 FCFA/month. GPS attendance saves a further 180 000 FCFA/month in ghost hours. Total: 480 000 FCFA/month. His app cost 4 000 000 FCFA: paid off in under 9 months, and he now pays workers in mobile money every week, with no cash handling.

FAQ
How does GPS attendance work?
Each worker clocks in and out via the app, with GPS position and timestamp. The manager sees in real time who is present on which site, which eliminates ghost hours.
Does the app work offline?
Yes, attendance and photo reporting work offline and sync as soon as the network returns. This is essential on poorly covered sites.
How is mobile money pay handled?
Clocked hours feed a payroll calculation; payment is made in mobile money (Wave, Orange Money) each week, with a receipt for each worker. This removes cash and secures funds.
How many sites can be tracked?
The multi-site dashboard handles several sites simultaneously, with a consolidated view of attendance, stock and photo progress.
How long to deploy?
An attendance module in 4 to 6 weeks, a standard version with stock and reporting in 8 to 12 weeks.
