The verdict in three sentences
The client who gets a clear quote in 5 minutes signs while still motivated; the one who waits 2 days has already called three other tradespeople. A smartphone quote and invoice app lifts the signature rate by about +30 % and triggers the mobile-money deposit before the first hammer swing. For 5,000 to 20,000 FCFA a month, you replace the paper notebook with cash-collection tracking that tells you who owes what, and when to chase.
Why quote speed changes everything
In construction and the trades, the first tradesperson to reply with a clean quote wins the job most of the time. The problem isn't price, it's delay: writing the quote by hand at night, copying it, photographing it, sending it over WhatsApp two days later. Meanwhile, the client is comparing.
| Situation | Manual quote | Mobile app |
|---|---|---|
| Time to send quote | 1 to 2 days | 5 to 10 min |
| Estimated signature rate | baseline | +30 % |
| Deposit collected before work | rare | Wave / OM in 1 link |
| Chasing a late client | forgotten | automatic |
| Compliant invoice (legal fields) | uncertain | generated by default |
| Cash-collection tracking | from memory | dashboard |
Speed is useless if the document looks amateur. An app enforces a template: logo, contact details, VAT where applicable, payment terms, 30-day validity. The client feels a structured professional, not a casual laborer.
What it costs and what it returns
The 2026 offers for West Africa cluster around three tiers. Order of magnitude, hosting and support included.
| Tier | Price/month (FCFA) | Quotes/invoices | Key features |
|---|---|---|---|
| Solo | 5,000 | unlimited | Quote, invoice, mobile-money deposit |
| Artisan+ | 12,000 | unlimited | Auto reminders, price catalog, 2 users |
| Team | 20,000 | unlimited | Multi-site, cash tracking, accounting export |
A single job won thanks to speed pays for several months of subscription. On an average quote of 350,000 FCFA, signing one extra job a month is additional revenue far above the tool's cost.

Mini case study
Moussa, a tiler in Thiès, was losing one job in three for lack of a fast enough quote. He sent his prices 2 days after the visit. In March 2026 he switched to an app at 12,000 FCFA/month. First-quarter result: quote sent in 8 minutes from the site, a 30 % deposit collected via Wave on the spot. He signs 2 extra jobs a month at 300,000 FCFA on average, or 600,000 FCFA of additional monthly revenue. Tool cost: 12,000 FCFA. Payback: day one.
FAQ
Does the app work without a connection on site?
Yes, the quote is prepared offline and sends the moment the network returns. The deposit payment link does need a connection, but 30 seconds of 3G is enough to generate a Wave or Orange Money link.
Can I collect a deposit directly?
Yes. The app generates a mobile-money payment link attached to the quote. On a 350,000 FCFA quote, a 30 % deposit (105,000 FCFA) secures the job before you buy materials.
Is the invoice compliant for the tax authorities?
It includes the required fields: identity, NINEA where applicable, date, breakdown of services, total and terms. You keep a searchable history, useful in a check or dispute.
How long to get running?
Less than a day: import your logo, build your recurring price catalog, send your first quote. No technical skill required.
What if I manage several workers?
The Team tier at 20,000 FCFA/month allows several users, multi-site tracking and the collections table to see at a glance who has paid.
