The verdict in three sentences
A custom tool automating the quote-invoice-reminder cycle for a Dakar SME costs 2,000,000 to 8,000,000 FCFA in 2026, with online quotes, PDF invoices, automatic reminders and integrated Wave / Orange Money payment. It cuts the payment delay (DSO) by several weeks and reduces bad debt. The real issue isn't the invoice, it's cash flow: getting paid faster changes everything for an SME.
Cost by approach: SaaS vs custom
The choice depends on invoice volume, Wave/OM integration needs and business customization. Here are 2026 orders of magnitude in Dakar.
| Approach | Build cost | Recurring | Best for |
|---|---|---|---|
| Generic SaaS | 0 - 300,000 FCFA (setup) | 6,000-30,000 FCFA/month | Getting started, low volume |
| Custom standard | 2,000,000 - 4,000,000 FCFA | Hosting 25,000-75,000 FCFA/month | Wave/OM + auto reminders |
| Custom advanced | 4,000,000 - 8,000,000 FCFA | Maintenance 50,000-150,000 FCFA/month | Multi-user, ERP, reporting |
SaaS starts cheaper but often imposes limits (no native Wave, no customization). Custom pays off as soon as volume or payment integration matters.
Impact on cash flow and bad debt
Automatic reminders and one-click payment radically change payment behavior. Estimates for a B2B SME in Dakar.
| Metric | Without automation | With automation | Gain |
|---|---|---|---|
| Average payment delay (DSO) | 55-75 days | 30-45 days | -25 to -30 days |
| Bad-debt rate | 6-10% | 2-4% | 2x to 3x lower |
| Reminder time/week | 5-8 h | 0.5-1 h | ~85% |
| Invoicing errors | frequent | rare | Fewer disputes |
| Wave/OM payment | manual | one click | Faster collection |
Why Wave and Orange Money change the game
Embedding Wave and Orange Money directly in the invoice (link or QR code) removes friction: the client pays from their phone in seconds. Reconciliation is automatic and the invoice flips to "paid" without intervention. It's the number-one lever to cut DSO in Senegal.
Mini case study
Mr. Sow, manager of a 22-employee services SME in Dakar, issues 90 invoices/month for monthly revenue of 18,000,000 FCFA. His DSO is 65 days and bad debt reaches 8%, i.e. ~1,440,000 FCFA/month at risk. A custom tool at 4,500,000 FCFA + 60,000 FCFA/month brings DSO to 40 days and bad debt to 3%. Cash freed by the lower DSO: the equivalent of about 15,000,000 FCFA of working capital recovered once. Bad debt avoided: ~900,000 FCFA/month. ROI in under 6 months.
