The verdict in three sentences
A tradesman who sends his quote three days after the visit has already lost half the jobs. An app turns the visit into a costed quote on the spot, collects a deposit via mobile money and rolls straight into the invoice. For a plumber or electrician in Nairobi, budget 1,500,000 to 4,000,000 FCFA for a tool that raises closing by 20 to 40 %.
Handwritten estimate versus quote app
The handwritten estimate is slow, unreadable and non-binding. The app makes it instant, professional and secured by a deposit that locks the client in.
| Step | Handwritten estimate | App 2026 |
|---|---|---|
| Time to send | 1 to 3 days | Immediate, on the spot |
| Readability | Variable, crossings-out | Clean PDF in your brand |
| Material and labor lines | Mixed, approximate | Separated, auto calculation |
| Deposit | Rare, cash | Mobile money, traced |
| Site photos | Absent | Attached to the quote |
| Follow-up | Lost track of | Status: sent, accepted, paid |
The quote-to-payment funnel
The strength of the app is chaining without a break: visit, quote, deposit, job, invoice, receipt. Every step is timestamped.
| Funnel step | Action | Typical delay |
|---|---|---|
| Visit | Photos + measurements in app | On the spot |
| Quote | Material + labor lines | 5 to 10 minutes |
| Deposit | 30 to 50 % via mobile money | Immediate |
| Scheduling | Job slot reserved | Same day |
| Final invoice | Balance + automatic receipt | End of job |
| Reminder | Balance reminder on day 3 | Automatic |
The effect on conversion
A fast quote and a deposit requested at the right moment radically change the acceptance rate. Here is an observed order of magnitude.
| Indicator | Without app | With app |
|---|---|---|
| Average time to send quote | 2 days | Immediate |
| Acceptance rate | 30 to 40 % | 50 to 60 % |
| Deposit collected on agreement | Rare | Systematic (30-50 %) |
| Unpaid balances at job end | Frequent | Rare, balance reminded |
| Admin time per week | 6 to 8 h | 1 to 2 h |
Mini case study
Ibrahim, a plumber in Nairobi, receives 40 quote requests a month and signs 14, a closing rate of 35 %. The average job is worth 120,000 FCFA. With the app, his closing rises to 50 %, i.e. 20 jobs. That is 6 more jobs a month, about 720,000 FCFA of extra monthly revenue. His app, billed at 2,500,000 FCFA, is recouped in under four months, before counting the admin time saved.

Does the app work offline in the field?
