The verdict in three sentences
A construction project management app brings the three cost drivers under control: budget, labor and material deliveries. Moving from Excel + WhatsApp to a dedicated tool cuts budget overrun from 15 % to 5 % and reduces delivery delays by 30 %. The classic choice: a custom platform or a per-site SaaS.
The modules that master a site
Across 6 simultaneous sites, information gets lost between the site manager, the storekeeper and management. Good software centralizes worker clock-in, the daily photo report, material tracking and live margin calculation.
| Module | Without software | With software 2026 |
|---|---|---|
| Budget overrun | ~15 % | ~5 % |
| Worker clock-in | Paper, disputable | Geolocated mobile |
| Daily report | Sporadic | Timestamped photo |
| Material delivery delay | Baseline | -30 % |
| Margin tracking | End of project | Real time |
| Sites tracked in parallel | Hard | 6+ with no loss |
Real-time margin tracking is the module that changes everything: instead of discovering a loss-making site at handover, management watches margin erode week by week and can correct course.
Build or SaaS: the math by site count
Build: Kolonell develops a custom platform (around 1,000,000 FCFA) with your cost lines and indicators. SaaS: around 30,000 FCFA/month per site. The more sites you run in parallel, the more build wins.
| Sites | SaaS/year (30,000 FCFA/mo) | Build (yr 1) | Build (yr 2+) |
|---|---|---|---|
| 2 sites | 720,000 FCFA | 1,000,000 FCFA | maintenance |
| 4 sites | 1,440,000 FCFA | 1,000,000 FCFA | maintenance |
| 6 sites | 2,160,000 FCFA | 1,100,000 FCFA | maintenance |
| 10 sites | 3,600,000 FCFA | 1,200,000 FCFA | maintenance |
From 4 parallel sites, build is cheaper from year one. A small firm with 1-2 sites can start on SaaS then switch as activity grows.

Mini case study
Saidou runs a construction firm in Johannesburg with 6 simultaneous sites, total budget 300,000,000 FCFA/year. An average 15 % overrun means 45,000,000 FCFA vanishing. With the custom platform (1,000,000 FCFA), overrun falls to 5 %, or 15,000,000 FCFA: the gap saved is 30,000,000 FCFA/year. The platform pays back in the first month on budget control alone, before counting delivery delays avoided.
FAQ
How does worker clock-in work? The team lead clocks in the present workers on mobile, with site geolocation. No more disputable paper sheets: payroll rests on real hours, cutting disputes and over-billing.
Is the daily report really useful? Yes: a few timestamped photos and a short note per day give management a faithful view of progress without traveling. In a client dispute, this evidence is invaluable.
How does the software reduce material delays? It tracks orders and alerts before shortages, based on consumption pace. Anticipating a cement order by a few days avoids halting a whole crew for lack of materials.
Can you monitor multiple sites at a glance? Yes, a consolidated dashboard shows progress, budget spent and margin for each site. Management instantly spots the site going off track.
Do you need good connectivity on site? No: clock-in, photos and reports are entered offline and sync when the network returns, which suits peripheral, poorly covered sites.
