The verdict in three sentences
A quoting and invoicing app for contractors generates take-offs, itemized quotes, VAT and clean invoices in minutes, with built-in mobile money collection. A structured quote raises the win rate by 15 to 25 % and mobile money collection cuts unpaid invoices by roughly 20 %. Budget 800,000 to 2,500,000 FCFA to buy or 15,000 to 40,000 FCFA/month as SaaS, for 5 to 8 hours saved each week.
Pro quote versus handwritten quote
| Criterion | Handwritten quote | App quote |
|---|---|---|
| Production time | 1-2 h | 15-20 min |
| Win rate | Baseline | +15-25 % |
| VAT calculation errors | Frequent | Automatic |
| Professional image | Weak | Strong |
| Follow-up | Often forgotten | Automated |
A clear, costed, well-presented quote inspires trust: a client hesitates less to sign a professional document than a scribbled figure.
Collection and unpaid invoices
| Lever | Without app | With app + mobile money |
|---|---|---|
| Collection delay | 30-60 days | Immediate possible |
| Unpaid rate | Baseline | ~-20 % |
| Invoice reminders | Manual | Automatic SMS |
| Cash-flow tracking | Rough | Real time |
Two pricing models
| Plan | 2026 cost | For whom |
|---|---|---|
| One-off purchase | 800,000-2,500,000 FCFA | Established firm |
| Monthly SaaS | 15,000-40,000 FCFA/month | Starting contractor |
Mini case study
Ibrahim, a tiler in Dakar, produced 8 quotes a month with a 40 % win rate, about 3 jobs. With pro quotes his rate rises to 50 % (+25 %), i.e. 4 jobs monthly. At 350,000 FCFA average margin per job, that is +350,000 FCFA/month. The SaaS app at 25,000 FCFA/month pays off in the first week, and he also saves 6 hours of weekly paperwork.
