The verdict in three sentences
A Nairobi construction site run without a central tool overruns 15 to 30% on budget and schedule, between rework, theft and progress-payment disputes. Two gains dominate: the photo daily report that cuts disputes 60% and material tracking that curbs theft by 10 to 18% (2026 order-of-magnitude estimate). The choice is between project-management SaaS and a custom app tailored to your milestones and subcontractors.
Construction SaaS or custom app
SaaS starts fast and suits standard use. Custom matches your payment milestones, time-clock and reports, with no recurring fee.
| Criterion | Construction PM SaaS | Custom app |
|---|---|---|
| Upfront cost | 0 FCFA | 5,500,000 – 10,000,000 FCFA |
| Monthly subscription | 70,000 – 160,000 FCFA | 0 FCFA |
| 3-year cost | 2,520,000 – 5,760,000 FCFA | 5,500,000 – 10,000,000 FCFA |
| Photo daily report | Standard | Custom |
| Geolocated worker clock-in | Vendor-dependent | Integrated |
| Milestone mobile money schedule | Rare | Integrated |
| Material tracking / anti-theft | Basic | Detailed per batch |
Where overruns are recovered
A site's losses sit in disputes, theft and coordination time. A site manager costs about 350,000 FCFA/month; central tracking spares them the back-and-forth and rework.
| Line item | Without app | With app | Gain |
|---|---|---|---|
| Budget/schedule overrun | 15 – 30% | Tight tracking | Margin preserved |
| Progress-payment disputes | Frequent | −60% | Secured payments |
| Material theft | 10 – 18% | Per-batch traceability | Loss reduced |
| Worker clock-in | Paper, contested | Geolocated | Fair pay |
| Progress proof | Word of mouth | Time-stamped photo | Dispute settled |
Mini case study
Ange runs a construction firm in Nairobi on a 120,000,000 FCFA site. An average 20% overrun meant 24,000,000 FCFA of extra costs, much of it in progress disputes and material theft. With photo daily reports (disputes −60%) and material tracking (theft down from 15% to 4% on affected lines), he saves on the order of 9,000,000 to 12,000,000 FCFA on this one site. An 8,000,000 FCFA custom app pays off on the first large project.

How much does a custom construction tracking app cost in 2026?
Budget 5,500,000 to 10,000,000 FCFA depending on complexity (multi-site, clock-in, payment schedule). A construction PM SaaS runs 70,000 – 160,000 FCFA/month.
Do photo daily reports really cut disputes?
Yes. A time-stamped, geolocated photo is authoritative on progress. Progress-payment disputes with the client or subcontractors drop about 60%.
How does the app limit material theft?
By tracking ins and outs per batch and per site, it surfaces discrepancies in real time. Theft, often estimated at 10-18% on some lines, falls sharply.
Is geolocated worker clock-in reliable?
Clock-in uses GPS position on site, time-stamped. It ends attendance disputes and enables exact pay, a real issue when crews rotate.
Can payments be tied to mobile money milestones?
Yes. The payment schedule can be linked to validated milestones and settled via mobile money, securing site cash-flow and clarifying what's owed at each stage.
