The verdict in three sentences
An invoicing → accounting connector runs 5 to 11 M FCFA (approx. EUR 7,600-16,800) in 2026; add 2.5 to 5 M FCFA for automatic Wave and Orange Money payment reconciliation. Handling VAT, fiscal periods and adjustment entries adds 1.5 to 3 M FCFA but is what makes the connector genuinely reliable for accounting. The payoff: 60 to 80% fewer entry errors and faster closes.
The 2026 line-by-line pricing
The core is the connector that pushes each issued invoice into the accounting software, then feeds back payment status. Below are 2026 orders of magnitude for a structured SME.
| Item | 2026 range (FCFA) | Detail |
|---|---|---|
| Invoicing → accounting connector | 5,000,000 - 11,000,000 | Invoice export, chart of accounts |
| Wave/OM payment reconciliation | 2,500,000 - 5,000,000 | Auto matching |
| VAT + fiscal periods | 1,500,000 - 3,000,000 | Entries, rates, closes |
| Error recovery + logging | 1,200,000 - 2,500,000 | Idempotent replay |
| Accounting UAT + parallel run | 1,000,000 - 2,200,000 | Control double entry |
| Accounting team training | 400,000 - 900,000 | Runbook + support |
Recurring cost and reliability: the finance director's real concern
An accounting connector tolerates no approximation: a missing or duplicated entry distorts the balance sheet. Idempotency and automatic mobile-money matching are therefore non-negotiable.
| Recurring item | 2026 cost | Note |
|---|---|---|
| Middleware hosting | 50,000 - 140,000 FCFA/month | Cloud or local |
| Annual maintenance | 18% of build | API changes |
| Wave/OM reconciliation | Included in maintenance | Webhooks to monitor |
| Backups + retained logs | 15,000 - 40,000 FCFA/month | Traceability |
Realistic timeline: 4 to 8 weeks in 2026, with a parallel-run phase (old + new flow) before full cutover.

Mini case study
Mamadou, finance director of a distribution firm, issues 600 invoices/month re-keyed by hand into accounting, plus reconciling Wave and Orange Money payments. Two half-time staff, about 1.4 M FCFA/month loaded cost. The invoicing → accounting connector with Wave/OM reconciliation is quoted at 9.5 M FCFA, hosting 90,000 FCFA/month, maintenance 18%. With 70% fewer errors and time recovered, payback lands around 8 months.
FAQ
Does the connector handle Wave and Orange Money payments? Yes, that is the key advantage: confirmation webhooks feed back the payment and auto-match the invoice. Budget 2.5 to 5 M FCFA for this reconciliation module.
How do you guarantee no entry is lost or duplicated? Through idempotency: each invoice carries a unique ID replayed without duplication on failure. That is the "error recovery" line in the quote; never cut it to save money.
Is a double-entry period needed? Yes, a 2-to-4-week parallel run reassures the accounting team and lets you compare entries before switching off the old process.
What is the annual maintenance budget? Around 18% of build cost, i.e. 1.5 to 2 M FCFA/year on a 9.5 M FCFA connector, to track API changes and VAT rate updates.
Does the connector respect fiscal periods? Yes if it handles period dates, adjustment entries and closes. This module (1.5-3 M FCFA) avoids manual rework at each period end.
