The verdict in three sentences
For a tradesperson, quote speed makes the sale: a quote sent within the hour converts far better than one promised for the next day. A dedicated app builds the quote on site, collects the deposit in Mobile Money and automatically chases overdue invoices. The 2026 result: more jobs signed and unpaid invoices cut by about 30 %.
The real problem: the gap between visit and quote
The carpenter, electrician or tiler loses clients not on price but on delay. A prospect waiting three days for a quote has already called a competitor. A tradesperson app lets you build a quote in 5 minutes from the phone, with a library of services and prices, then convert it to an invoice in one tap once the job is accepted.

Mini case study
Ibrahim is a plumber in Abidjan handling about 20 quotes a month at an average of 180,000 FCFA. At 25 % conversion he signs 5 jobs (900,000 FCFA). With a 750,000 FCFA app that lifts conversion to 40 %, he signs 8 jobs (1,440,000 FCFA), i.e. +540,000 FCFA of revenue per month. By cutting unpaid invoices from 18 % to 12 % on that volume, he also recovers ~86,000 FCFA. The tool pays for itself in the first month.

FAQ
Is the quote compliant and professional?
Yes. The app produces a numbered quote with your details, VAT and terms. The client can accept it online, which counts as a commitment.
How does the deposit cut unpaid invoices?
Collecting 30 to 50 % at signing via Wave or MoMo secures cash flow and commits the client. In the field, this sharply reduces cancellations and late payments.
Are reminders automatic?
Yes. The app sends an SMS or WhatsApp reminder at D+7, D+15 and D+30. This consistency explains much of the drop in unpaid invoices.
Can I track several jobs at once?
Yes, in the Team and Pro plans. Each job has its status, photos, invoices and margin, all viewable from the phone.
