The verdict in three sentences
A tradesperson noting quotes in a pad and invoicing by text loses jobs by replying too late and loses money on deposits they never ask for. A smartphone quote and invoice app generates a clean quote in 3 minutes, sends it over WhatsApp and collects the mobile money deposit immediately. Measured effect: -50 % admin time and quotes accepted twice as fast.
What the app changes day to day
A tradesperson's job is fixing things, not paperwork. The app turns the phone into a sales tool: priced quote on the spot, instant send, secured deposit before the first turn of the wrench.
| Feature | Concrete benefit | Order of magnitude (2026) |
|---|---|---|
| Fast smartphone quote | Priced on site in 3 minutes | Quotes issued 2x faster |
| WhatsApp send | Client receives and approves in 1 tap | Acceptance +50 % |
| Mobile money deposit | 30 to 50 % collected before work | Unpaid bills halved |
| Automatic invoice | Numbered PDF, VAT calculated | 0 calculation errors |
| Arrears reminder | Auto nudge D+7 and D+15 | Payment delay -40 % |
| Client history | Quotes, invoices, jobs | Easy follow-up and loyalty |
The mobile money deposit is the detail that changes everything: asking for 40 % before starting eliminates most unpaid bills and funds material purchases without dipping into your own cash.
What the app costs
| Package | Scope | Indicative 2026 price |
|---|---|---|
| Starter | Quote + invoice + WhatsApp send | GHS 15,000 |
| Growth | Mobile money deposit, reminders, history | GHS 30,000 |
| Premium | Multi-trade, scheduling, materials stock | GHS 56,000 |
| Maintenance | Hosting, updates, support | GHS 750 to 1,900/month |
For a solo tradesperson, the Starter package is often enough; Growth pays off once volume exceeds 15 quotes a month.

Mini case study
Kwame is an electrician in Accra issuing about 20 quotes a month for an average turnover of GHS 45,000. Before the app, 30 % of his quotes went unanswered for lack of follow-up and 4 invoices a month dragged unpaid. After the Growth package (GHS 30,000): WhatsApp send lifts the acceptance rate, mobile money deposits secure jobs, and automatic reminders cut payment delay from 45 to 20 days. He recovers 5 hours a week and gets paid faster; the tool is recouped in about 3 months.
FAQ
Do I need to know how to use a computer? No, everything runs on a smartphone with a simple interface; a tradesperson creates their first quote in under 5 minutes after a short walkthrough.
Does the client need to install an app to pay? No, they receive an MoMo or card payment link over WhatsApp and pay in seconds, with nothing to install.
Is the mobile money deposit expensive? Fees run around 1 % to 1.5 % per transaction; on a GHS 3,000 deposit that is roughly GHS 30 to 45, easily offset by fewer unpaid bills.
Can I manage several tradespeople in one team? Yes, the Premium package (GHS 56,000) handles multiple tradespeople, a shared schedule and materials stock tracking.
How long to go live? A Starter package is ready in 2 to 3 weeks; a Growth package with mobile money deposits and reminders in 4 to 6 weeks.
