The verdict in three sentences
A custom construction software covering sites, quotes and time tracking costs between 8,000,000 and 28,000,000 FCFA in 2026, scaling with the number of concurrent sites and field mobile use. The real return comes not from the price but from recovered site margin: precise tracking of hours and materials recovers 2 to 5 margin points. On a company invoicing 400,000,000 FCFA/year, 3 margin points = 12,000,000 FCFA, meaning the tool pays for itself in under a year.
Price ranges per module
Amounts are 2026 orders of magnitude, delivered with a field mobile app (Android) and foreman training.
| Module | 2026 range | Priority |
|---|---|---|
| Sites core + dashboard | 3,500,000 – 5,000,000 FCFA | Essential |
| Quotes / takeoff + price library | 2,500,000 – 4,000,000 FCFA | Essential |
| Mobile time tracking + geolocation | 2,000,000 – 3,500,000 FCFA | Essential |
| Material tracking + site stock | 1,800,000 – 3,000,000 FCFA | High |
| Progress billing + invoicing | 2,200,000 – 3,500,000 FCFA | High |
| Subcontractors + retention | 1,500,000 – 2,500,000 FCFA | Medium |
| Margin reporting per site | 1,500,000 – 2,800,000 FCFA | High |
An "essential" scope (first 3 modules) therefore starts around 8,000,000 – 12,500,000 FCFA, deliverable in 8 to 12 weeks.
ROI on site margin
Mobile time tracking and material tracking are the two levers that pay for the tool. Simulation for three company sizes.
| Annual revenue | +3 margin pts | Tool cost | Yr 1 ROI |
|---|---|---|---|
| 150,000,000 FCFA | 4,500,000 FCFA | 10,000,000 | negative, positive yr 2 |
| 400,000,000 FCFA | 12,000,000 FCFA | 14,000,000 | near neutral |
| 900,000,000 FCFA | 27,000,000 FCFA | 20,000,000 | +7,000,000 FCFA |
Above 400,000,000 FCFA in revenue, the tool self-funds quickly through recovered unbilled hours and reduced material theft/loss.

Mini case study
Mr. Ndiaye, owner of a 45-employee structural works company on the outskirts of Dakar, managed 6 concurrent sites in Excel and lost precise hour tracking. On the last 3 sites, hour under-estimation had cost roughly 9,000,000 FCFA in margin. Kolonell quoted custom software (core + quotes + mobile tracking) at 13,500,000 FCFA. By securing time tracking and takeoff, he targets 3 margin points on 350,000,000 FCFA of revenue, i.e. 10,500,000 FCFA/year — tool repaid in about 16 months.
FAQ
What is a realistic entry price? A sites + quotes + mobile tracking core starts around 8,000,000 – 12,500,000 FCFA, excluding advanced modules like progress billing.
Is the field mobile app included? Yes, an Android tracking app with geolocation represents 2,000,000 to 3,500,000 FCFA and works offline for poorly covered sites.
How long to go live? A pilot on one site ships in 6 to 8 weeks; full multi-site deployment in 10 to 14 weeks.
Can subcontractors and retention be managed? Yes, this module costs 1,500,000 to 2,500,000 FCFA and automates retention calculation and release at handover.
Is custom justified versus an off-the-shelf construction suite? As soon as you run more than 4-5 concurrent sites with specific processes, custom avoids per-user licenses and matches your progress billing.
