The verdict in three sentences
A quote scribbled on a table corner and a site tracked from memory blow margins by 10-25%. An app that frames quotes, purchases and mobile money deposits makes every site controllable and recovers lost margin. Quote production time falls 50%, overruns 8-15%, and profitability arrives from just a few sites per month.
Excel/paper vs quote app + cost tracking
Paper links neither the quote, the purchases, nor the deposits. The app tracks the site from pricing to final settlement.
| Criterion | Excel / paper | Quote app + tracking + deposits |
|---|---|---|
| Average cost drift | 10-25% | -8 to -15% |
| Quote production time | Baseline | -50% |
| Quotes lost without follow-up | High | Auto follow-ups |
| Deposit collected | Cash, deferred | 30-40% instant mobile money |
| Purchases vs quote tracking | None | Real time |
| Margin visibility per site | End of site | Continuous |

Mini case study
Jean-Marc, a construction firm in Accra, runs 6 sites/month for 18,000,000 FCFA in sales. Average cost drift of 18%, i.e. ~3,240,000 FCFA of margin evaporating. A 2,200,000 FCFA app: purchases-vs-quote tracking and 35% deposits via mobile money. Overruns fall to 6% (-12 pts), recovering ~2,160,000 FCFA/month, and quotes go out twice as fast. The app is repaid in just over a month.
FAQ
How does the app reduce overruns? By linking each purchase to the original quote and alerting as soon as a line exceeds budget, it brings cost drift from 10-25% down by 8-15%.
Why collect the deposit in mobile money? A 30-40% deposit collected instantly via Wave or Orange Money secures start-up cash flow and reduces non-payment risk, with 1-1.5% fees.
How much time is saved on a quote? With a reusable library of prices and line items, quote production time drops 50%, letting you chase more prospects.
From how many sites is it worth it? From 4-6 sites/month, saved margin exceeds the 800,000-3,000,000 FCFA app cost within one to two months.
