The verdict in three sentences
A site run by phone and notebook drifts silently: workers mis-clocked, materials that evaporate, a client kept in the dark. A construction site app (photo progress, worker clock-in, material stock, daily report) cuts delays by about 20% and material waste by 12%. In Accra as in Dakar, exporting a daily report to the client transforms the relationship and secures milestone payments.
What each module controls
The real challenge in construction is not pretty software, it is holding the deadline and the material margin. Here is the impact per module, as a 2026 order of magnitude for a builder managing 3 to 15 sites.
| Module | What it does | Measurable gain | Indicative price |
|---|---|---|---|
| Worker clock-in | Geo-located attendance, real hours | -15% inflated payroll | 450,000 FCFA |
| Photo progress | Timestamped photos per task/stage | -20% progress disputes | 500,000 FCFA |
| Material stock | Inflows/outflows, alert thresholds | -12% waste/theft | 550,000 FCFA |
| Daily report | Auto PDF sent to client/foreman | Trust + milestone payments | 400,000 FCFA |
| Task planning | Milestones, dependencies, delay flags | -20% schedule drift | 500,000 FCFA |
| Multi-site dashboard | Cost/progress per site | Global steering | included |
Price, timeline and sites tracked
A full project runs from 1,500,000 to 5,000,000 FCFA depending on the number of sites, workers and financial reporting depth.
| Package | Content | Sites tracked | Price FCFA | Timeline |
|---|---|---|---|---|
| Site | Clock-in + progress + report | 1 to 3 | 1,500,000 – 2,200,000 | 4-5 weeks |
| Company | + material stock + planning | 3 to 10 | 2,600,000 – 3,800,000 | 6-9 weeks |
| Construction group | + financial dashboard + roles | 10+ | 4,000,000 – 5,000,000 | 10-12 weeks |
| Custom | Accounting/procurement integration | variable | quote | 12-14 weeks |

Mini case study
Kwame, owner of a construction SME in Accra with 4 sites and 60 workers, sees 18% schedule overrun and a material budget of 40,000,000 FCFA/year with 12% waste/theft. With the Company package (3,200,000 FCFA), geo-located clock-in makes payroll reliable and stock tracking brings waste to 5%. Material saving: 40,000,000 × (12% - 5%) = 2,800,000 FCFA/year, plus fewer delays avoiding penalties. The app pays back in under 4 months, and daily reports speed up client disbursements.
FAQ
Does clock-in work on a site with no network? Yes, workers and foremen clock in offline; data syncs when the network returns. Geolocation prevents ghost clock-ins.
How does the app cut material waste? Every stock inflow and outflow is logged with alert thresholds, making discrepancies visible. In practice waste/theft often falls from 12% to 5%.
Does the client really get a report every day? Yes, an automatic PDF with timestamped photos, progress and incidents. This transparency secures milestone payments and reduces end-of-project disputes.
Can several sites be tracked at once? Yes, from 1 to 3 sites in the Site package up to more than 10 with a consolidated financial dashboard in the Construction group package.
