The verdict in three sentences
A custom construction site management app costs between 1,500,000 and 6,000,000 FCFA in 2026 depending on modules and offline mode, essential on poorly covered sites. It targets construction's two black holes: material losses (theft, waste, over-ordering) and delays from lack of visibility. Expect 8 to 14 weeks for a V1 usable by site managers in the field.
Features and price per module
| Module | Role | Indicative price FCFA |
|---|---|---|
| Planning & tasks | Phases, milestones, delays | 400,000 – 900,000 |
| Worker time tracking | Attendance, hours, geoloc | 400,000 – 1,000,000 |
| Material/stock tracking | In/out, thresholds | 500,000 – 1,200,000 |
| Expenses & budget | Purchases, quote comparison | 400,000 – 1,000,000 |
| Progress photos | Dated, geolocated proof | 300,000 – 700,000 |
| Supplier payment | Wave/OM, history | 400,000 – 1,000,000 |
| Offline mode | Sync on network return | 600,000 – 1,400,000 |
A "time tracking + materials + expenses" V1 starts at 1,500,000 – 2,800,000 FCFA. A full multi-site platform with offline mode and supplier payment reaches 5,000,000 to 6,000,000 FCFA.
Losses avoided and ROI
| Leak source | Before app | After app |
|---|---|---|
| Material losses | 8 – 15% of budget | 3 – 5% |
| Ghost hours (time tracking) | 5 – 10% of payroll | < 2% |
| Undetected delays | Frequent | Early alerts |
| Supplier disputes | High | Full traceability |
| Management reporting | Manual, late | Real time |
On an 80,000,000 FCFA site with 12% material losses, bringing that rate down to 4% saves 6,400,000 FCFA — more than the cost of the most complete app. Digital time tracking additionally recovers a few percent of wrongly paid payroll.

Ousmane runs a construction SME in Abidjan with 3 active sites and a monthly materials budget of 25,000,000 FCFA. His losses ran at 10%, i.e. 2,500,000 FCFA/month. With stock tracking, alert thresholds and dated photos, he drops to 4%, saving 1,500,000 FCFA/month. The 3,200,000 FCFA app pays for itself in just over 2 months, not counting the end of ghost hours.
FAQ
How much does a site management app cost? A V1 (time tracking, materials, expenses) starts at 1,500,000 FCFA; a full multi-site platform goes up to 6,000,000 FCFA.
Does it work without a network on site? Yes, offline mode records attendance, photos and stock movements, then syncs on network return. This module adds 600,000 to 1,400,000 FCFA but is nearly unavoidable.
How does the app reduce material losses? By tracking every stock movement with alert thresholds and a designated owner, losses typically drop from 8-15% to 3-5% of the materials budget.
Can you pay suppliers from the app? Yes, via Wave/Orange Money with full history, which removes "who paid what" disputes and speeds up supply.
Is worker time tracking reliable? Geolocated digital time tracking eliminates ghost hours (5-10% of payroll) and provides an indisputable basis for pay.
