The verdict in three sentences
A Kumasi artisan writing quotes by hand loses 20 to 30 % of jobs for lack of follow-up and underprices margin because costs are invisible. A mobile quote-invoice app cuts quote editing from 40 to 5 minutes, sends the document via WhatsApp and collects the deposit through Mobile Money. Between a SaaS at 5,000-20,000 FCFA/month and a custom app at 600,000-1,800,000 FCFA, the choice depends on your job volume and your need for a service catalog.
Monthly SaaS or custom app?
SaaS starts fast and cheap; custom fits your trades (carpentry, plumbing, electrical) with your prices, margins and logo. Here are the 2026 orders of magnitude.
| Criterion | Quote-invoice SaaS | Custom app |
|---|---|---|
| Upfront cost | 0 to 50,000 FCFA | 600,000 to 1,800,000 FCFA |
| Subscription | 5,000 to 20,000 FCFA/month | Hosting 10,000-25,000 FCFA/month |
| Service catalog | Generic | Custom, your prices |
| Margin calculation | Basic | Detailed per line |
| WhatsApp sending | Sometimes | Native |
| Mobile Money collection | Vendor-dependent | Wave + Orange Money built in |
| Data ownership | Vendor | You |
The measurable field impact
A clear, priced quote sent within the hour shifts the commercial balance. Gains observed (2026 estimate) when an artisan moves from notebook to app:
| Metric | On notebook | With the app |
|---|---|---|
| Quote editing time | 40 min | 5 min |
| Acceptance rate after auto follow-up | 35 % | 55 % |
| Average payment delay | 45 days | 20 days |
| Margin actually applied | Approximate | Tracked per line |
| Quotes lost for lack of follow-up | 25 % | 8 % |

Ousmane, a carpenter in Kumasi, signs on average 12 jobs a month at 180,000 FCFA. Moving from notebook to app, his acceptance rate after follow-up rises from 35 to 55 %: on 30 quotes sent, he signs 6 more jobs, i.e. 1,080,000 FCFA in extra revenue per month. The app cost him 900,000 FCFA once: it pays for itself in under a month of marginal gain.
FAQ
How much does an artisan quote-invoice app cost? Expect 5,000 to 20,000 FCFA/month for a SaaS, or 600,000 to 1,800,000 FCFA for a custom app with your catalog and built-in Mobile Money collection.
Does the app work offline on the job site? Yes, a well-built app stores the quote locally and syncs when the network returns; the artisan prices on site even on 2G.
Can I collect the deposit directly? Yes, with Wave and Orange Money built in, the client pays the deposit by link or QR code at signing, cutting payment delay from 45 to 20 days.
Does a professional quote really change the signing rate? Yes, a properly priced and presented quote raises the signing rate by 15 to 25 % versus a handwritten one, because it signals seriousness and price clarity.
How long to deploy the app? A SaaS is live in a day; a custom app ships in 3 to 6 weeks depending on catalog and integrations.
