The verdict in three sentences
Plumbers, electricians and carpenters lose jobs to slow quotes and forgotten follow-ups: a mobile app closes the same day and secures the deposit. The 2026 decision is generic invoicing tool or trade-specific app: the trade app wins because it handles material/labour line items, before/after photos and recurring maintenance contracts. Budget 600,000 to 2,000,000 FCFA for development — the most affordable trade investment in the whole catalogue.
The same-day quote makes the difference
In the trades, quote speed weighs as much as price. The customer calls three tradespeople; the first to reply, with a clear quote, wins the job.
| Quote turnaround | Win rate | Comment |
|---|---|---|
| Same day | 50-55% | Customer hasn't compared yet |
| Within 24 h | 38-42% | Still well placed |
| 2-3 days | 20-25% | Competitors already ahead |
| Over 3 days | 8-12% | Often too late |
| Never formalised | 0% | Job lost |
A tradesperson receiving 40 enquiries/month at an average ticket of 180,000 FCFA wins about 9 jobs/month replying in 3 days (22%). Switching to same-day quotes (52%), they win 21 jobs/month, or +12 jobs / +2,160,000 FCFA/month on the same enquiry flow.
Generic tool or trade app?
A general invoicing tool doesn't know the realities of the field. Here's what a dedicated app adds and its indicative cost (2026 order of magnitude).
| Feature | Content | Indicative cost |
|---|---|---|
| Fast mobile quote | Material + labour line items, WhatsApp send | 600,000 - 1,000,000 FCFA |
| Scheduling + reminders | Job calendar, customer and crew reminders | + 300,000 - 600,000 FCFA |
| Mobile money deposit | Wave/MoMo collection before start | + 300,000 - 500,000 FCFA |
| Before/after photos + VAT | Proof of work, VAT invoice | + 250,000 - 450,000 FCFA |
| Maintenance contracts + reminders | Recurring service, unpaid-invoice reminders | + 300,000 - 550,000 FCFA |
The mobile money deposit before start protects the tradesperson's cash flow: no job begins without a franc down. Recurring maintenance contracts (air conditioning, plumbing, electrical) turn a one-off job into predictable revenue, and automatic reminders on unpaid invoices recover money that was sitting idle.

Mini case study
Salif, an electrician in Johannesburg, receives 38 enquiries/month at a 170,000 FCFA average ticket. Replying in 3 days on average, he won 22%, about 8 jobs/month (1,360,000 FCFA). He invests 1,100,000 FCFA in a mobile quote app + Wave deposit + reminders. He now sends quotes the same day and wins 50%, about 19 jobs/month (3,230,000 FCFA). Gain: +1,870,000 FCFA/month. The app pays for itself in under three weeks, on top of unpaid invoices recovered by reminders.
FAQ
How much does a tradesperson app cost in 2026? Budget 600,000 to 2,000,000 FCFA depending on features: the fast mobile quote starts around 600,000 FCFA, while the full solution with scheduling, deposit, photos and maintenance contracts reaches 2,000,000 FCFA.
Why not just use a simple invoicing tool? A generic tool doesn't handle material/labour line items, before/after photos or the recurring maintenance contracts specific to the trades. The dedicated app closes faster and retains better.
How do I secure the deposit before starting? Wave or Orange Money integration lets you collect a deposit (often 30-50%) directly from the quote. No job starts without a deposit, which protects cash flow.
Does the app handle unpaid invoices? Yes, automatic reminders on unpaid invoices recover money effortlessly. Pairing those reminders with an upfront deposit sharply reduces customer risk.
Can it manage recurring maintenance contracts? Yes, a recurring maintenance module schedules interventions and invoices automatically. That's what turns a one-off job into predictable revenue month after month.
