The verdict in three sentences
A construction tradesman who writes quotes by hand takes days to reply and loses the job to a faster, more professional rival. A mobile quote, invoicing and mobile money payment-tracking app lets him send a priced quote in ten minutes from the site, lifting the win rate by 25% and cutting payment delay by 40%. For a tradesman or small firm in Lagos, the 1,500,000 to 4,000,000 FCFA investment pays back in 2 to 5 months.
The fast quote, a tradesman's sales weapon
In construction, the client who gets the first clear quote often signs. The tradesman who says "I'll call you back" and takes three days to scribble a figure has already lost. The problem isn't price, it's the speed and professionalism of the reply.
A mobile app changes the game: a pre-filled price catalog (labour, materials, services), a quote generated and sent as a PDF from the phone, an invoice converted in one tap, payment tracking via mobile money, and automatic reminders on overdue invoices.
| Feature | Main gain | Dev cost (FCFA) | Timeline | Impact |
|---|---|---|---|---|
| Mobile PDF quote | 10-minute reply | 700,000 | 2.5 wk | Win rate +25% |
| Price catalog | Reliable pricing | 400,000 | 1.5 wk | Quote errors -60% |
| One-tap invoice | Zero re-entry | 400,000 | 1.5 wk | Admin time -50% |
| Mobile money tracking | Faster collection | 600,000 | 2 wk | Payment delay -40% |
| Automatic reminders | Invoices paid | 400,000 | 1.5 wk | Arrears -35% |
Impacts are 2026 orders of magnitude for a tradesman or small construction firm.
