The verdict in three sentences
Without structured tracking, a site's budget overrun reaches 15 to 30 %; dedicated software brings it under control. A quote is produced in 15 minutes instead of 2-3 hours, and automated invoice follow-up shortens payment from 60 to 30 days. A construction software with mobile money invoicing costs the FCFA equivalent of 1,500,000 to 4,000,000.
Excel and WhatsApp or centralised software
Running a site with Excel quotes and photos scattered on WhatsApp creates gaps: slow pricing, fuzzy progress, handover disputes. Concrete comparison.
| Criterion | Excel + WhatsApp | Site software |
|---|---|---|
| Cost 2026 (FCFA eq.) | 0 - 150,000 | 1,500,000 - 4,000,000 |
| Time per quote | 2-3 h | 15 min |
| Progress tracking | Scattered | Central + photos |
| Budget overrun | 15-30 % | 5-12 % |
| Payment term | ~60 days | ~30 days |
| Invoicing | Manual | Mobile money |
| Handover disputes | Frequent | -30 to -50 % |
The costed impact on cash flow
Construction lives and dies by cash flow. Pricing fast, tracking budgets and chasing invoices automatically transform margins. 2026 order of magnitude for a construction SME.
| Metric | Without software | With software |
|---|---|---|
| Quotes produced/month | 8-12 | 20-30 |
| Quote conversion rate | 20-25 % | 30-40 % |
| Average overrun/site | 22 % | 9 % |
| Average payment term | 60 days | 30 days |
| Handover disputes | 3-5/month | 1-2/month |
| Admin hours saved/week | Baseline | 6-10 h |

Mensah Construction runs 10 sites/month, average budget the FCFA equivalent of 8,000,000, i.e. 80,000,000 monthly volume. With an average overrun of 22 %, uncontrolled costs eat the margin. It invests 2,500,000 in tracking software. Overrun falls to 9 %, i.e. 13 points saved on part of the sites: applied to just half the volume (40,000,000), that's about 5,200,000 in avoided costs. The investment is repaid in the first month, before even counting faster payment.
