The verdict in three sentences
An SME invoicing in Word and chasing payments by hand gets paid twice as late as one that is properly equipped. Invoicing software built for West Africa turns a quote into an invoice in one click, applies 18 % VAT, respects OHADA mentions, numbers legally, and automatically chases unpaid invoices with a Wave payment link embedded in the PDF. For 9,900 to 24,900 FCFA a month, it cuts payment time from 45 to 22 days and reduces unpaid invoices by 30 %.
What "compliant" actually means
An invoice is not a pretty PDF. To be enforceable and accepted by the tax authority and the customer alike, it must carry precise mentions. Good software handles them automatically, without you having to think about it.
| Required element | Detail | Handled by the tool |
|---|---|---|
| Sequential numbering | No gaps or duplicates | Automatic |
| VAT | 18 % (Senegal), net/gross base | Auto calculation |
| OHADA mentions | Identity, tax/registry no., date | Preset template |
| Quote → invoice | Conversion without re-keying | 1 click |
| Payment terms | Due date, late penalties | Configurable |
| Archiving | Legal retention | Secure cloud |
The gain is not only time: a compliant invoice avoids rejections, re-issued credit notes and disputes that delay payment.
Automatic reminders change your cash flow
The real lever is the reminder. Most delays are not bad faith but forgetfulness. A tool that chases on its own — at D+3, D+10 and D+20, with a clickable payment link — recovers the money without you having the awkward conversation.
| Metric | Manual invoicing | With reminders + Wave link |
|---|---|---|
| Average payment time | 45 days | 22 days |
| Unpaid rate | Baseline | -30 % |
| Invoicing time/month | 6-10 h | 1-2 h |
| Reminders sent | When remembered | Automatic (D+3/10/20) |
| Online payment | No | Wave/OM link in the PDF |
Cutting the delay from 45 to 22 days on revenue of 3,000,000 FCFA/month frees more than 2,000,000 FCFA of cash permanently in the cycle.
Positioning vs existing solutions
Tools like Facturo (9,900 to 24,900 FCFA/month depending on plan) already cover standard invoicing well. Custom development is justified when you have specific needs: integration with your stock, your POS, commission logic, multi-entity, or a particular quote-to-project flow.
| Option | 2026 cost | For whom |
|---|---|---|
| Facturo-style SaaS (Free) | 0 FCFA (5 invoices) | Micro, getting started |
| SaaS Starter | 9,900 FCFA/month | Freelancer, small SME |
| SaaS Pro | 24,900 FCFA/month | SME with volume |
| Custom tool | On quote | Specific needs/integrations |
Mini case study
Awa, who runs a services agency, invoices around 3,500,000 FCFA a month across 25 invoices. She was paid on average at 45 days and spent 8 hours a month chasing.

After switching to a tool at 24,900 FCFA/month:
- Payment time: 45 → 22 days, i.e. ~1.8M FCFA of cash freed in the cycle.
- Unpaid -30 %: on ~150,000 FCFA average annual unpaid, about 45,000 FCFA recovered.
- Invoicing time: from 8 h to 1.5 h a month, 6.5 h given back to her business.
For an annual cost under 300,000 FCFA, she gains cash, time and peace of mind. The Wave link in the PDF does the rest: the customer pays in three clicks.
