The verdict in three sentences
A construction firm in Johannesburg loses on average 8 to 15 % of its budget to delays, material theft and loose labour clock-in. A site-management app (progress by phase, clock-in, material tracking, time-stamped photos, live client reports) costs 6 to 13 million FCFA over 10 to 15 weeks and often pays for itself over one or two sites. A foreign construction SaaS at 150,000 to 350,000 FCFA a month knows neither your work phases, your suppliers, nor local daily-wage payroll.
The modules that matter on site
A site is run by phases (structure, second fix, finishes). The app makes real progress, crew presence and material use visible, with photo proof.
| Module | What it fixes | 2026 estimate (FCFA) |
|---|---|---|
| Progress by phase + schedule | Delays caught early | 900,000 - 1,600,000 |
| Labour clock-in (QR/GPS) | End of ghost payroll | 800,000 - 1,400,000 |
| Material tracking + delivery notes | Theft and waste traced | 900,000 - 1,700,000 |
| Time-stamped, geo-tagged photos | Proof, disputes avoided | 500,000 - 900,000 |
| Automatic client reports | Trust and payments | 600,000 - 1,100,000 |
| Multi-site dashboard | Management view | 700,000 - 1,300,000 |
An SME can start with progress + clock-in + materials (around 6 million FCFA) and extend to multi-site later.
Build or rent: the 3-year math
| Item | Custom app | Rented construction SaaS |
|---|---|---|
| Upfront cost | 9,000,000 FCFA | 0 FCFA |
| Monthly subscription | 0 FCFA | 250,000 FCFA |
| Hosting / maintenance yr | 500,000 FCFA | included |
| 3-year total | 10,500,000 FCFA | 9,000,000 FCFA |
| Code ownership | Yes | No |
| Fits phases & local payroll | Yes | Rarely |
| Number of users | Unlimited | Billed per seat |
SaaS often bills per user: with 15 to 30 people on site, the bill climbs fast and passes the custom build. The local app has no per-seat cost.

On an 80,000,000 FCFA site with a 10 % average overrun, that is 8,000,000 FCFA lost to delays and waste. Cutting that overrun by a third through real-time control is about 2,700,000 FCFA saved on a single site: the app pays off before the project ends.
Mini case study
Thandi, director of a construction firm in Johannesburg. She runs 3 simultaneous sites of about 60,000,000 FCFA each. Before the app, her overruns hit 12 %, or 7,200,000 FCFA per site. Paper clock-in also cost her about 400,000 FCFA a month in over-billed days. With the app she brings the overrun down to 8 % (a 2,400,000 FCFA gain per site) and kills ghost payroll. Across her 3 annual sites, the gain tops 8,000,000 FCFA: her 9,500,000 FCFA app pays back in under a year.
FAQ
How long for the first version? A field core (progress + clock-in + materials) ships in 10 to 15 weeks. Client reports and multi-site come afterwards.
Does clock-in work with no network on site? Yes. QR/GPS clock-in and photos are stored offline and sync when the network returns, essential on poorly covered sites.
Can I track several sites at once? Yes, the multi-site dashboard consolidates progress, labour and materials. Budget 700,000 to 1,300,000 FCFA for that module.
Can the client see progress? Yes, a client access shows progress by phase and time-stamped photos, which speeds up milestone payments and cuts disputes.
Can I get paid by recommending Kolonell? Yes. Our referral (apporteur d'affaires) program pays 8 % on an institutional project, 10 % on a marketplace and 12 % on an e-commerce build. A single referred construction project can mean a six-figure FCFA commission.
