The verdict in three sentences
Invoicing in Word or Excel in Senegal means taking three risks: non-sequential numbering (a ground for tax rejection), 18 % VAT calculated by hand and therefore wrong, and unpaid invoices nobody remembers to chase. A SYSCOHADA-compliant invoicing app locks legal numbering, calculates VAT automatically, turns a quote into an invoice in one click and triggers dunning on its own. Budget a 2026 order of magnitude of 400,000 to 800,000 FCFA and 5 to 8 weeks of development.
Word / Excel versus a compliant invoicing app
A copied Word template is not an invoicing system: nothing guarantees a unique number, nothing tracks collection, nothing chases the client. Here is the real gap.
| Criterion | Word / Excel | Invoicing app |
|---|---|---|
| Numbering | Manual, gaps and duplicates | Sequential, locked |
| 18 % VAT | Manual calculation | Automatic net / VAT / gross |
| Quote to invoice | Full re-typing | One-click conversion |
| Dunning | Forgotten | Auto at D+7 / D+15 / D+30 |
| Client delivery | Manual email | PDF + WhatsApp send |
| Accounting export | Re-keying | Direct SYSCOHADA export |
SYSCOHADA and VAT compliance: the figures that matter
OHADA regulation requires specific mentions and unbroken numbering. The app builds them in and documents every document.
| 2026 requirement | Rule | Handling by the app |
|---|---|---|
| Standard VAT rate | 18 % | Applied and split automatically |
| Numbering | Sequential, no gaps | System-generated, non-editable |
| Legal mentions | NINEA, RCCM, address | Mandatory pre-filled fields |
| Document retention | 10 years | Timestamped digital archiving |
| Quotes | Dated validity | Tracked conversion to invoice |
| Collection tracking | — | Status paid / partial / unpaid |

Ibrahim runs a services SME in Thiès, 25 invoices a month, average amount 350,000 FCFA. In Excel his DSO (days sales outstanding) hit 75 days and 3 invoices a month slipped through un-chased — 1,050,000 FCFA permanently locked up. With automatic dunning at D+7, D+15 and D+30, his DSO drops to 50 days and his oversights to zero. Recovered cash exceeds 1,700,000 FCFA in the first quarter. The app, bought for 600,000 FCFA, pays back before the end of the second month of use.
FAQ
Is the app truly SYSCOHADA-compliant? Yes: locked sequential numbering, legal mentions (NINEA, RCCM), net/VAT/gross breakdown and export in the format your accountant expects.
Can invoices be sent by WhatsApp? Yes, every invoice generates a PDF you can send in one click via WhatsApp or email, with a tracking link. It is the most effective channel in Senegal to get paid quickly.
Does it handle several VAT rates or exemption? Yes, the standard 18 % rate is the default, but the app manages exemption and non-taxable lines for the relevant activities.
What happens with a persistent unpaid invoice? After the D+30 reminder, the app flags the receivable in a dedicated dashboard and can move the case into structured collection tracking.
