The verdict in three sentences
In 2026 in Abidjan, an API connector between your billing tool and your ERP runs 3 to 9 million FCFA (roughly 4,600-13,700 EUR) depending on the number of flows and the reliability required. Delivery takes 4 to 8 weeks and relies on webhooks with error recovery so no data is lost. The immediate benefit: double entry disappears, and with it the gaps between billing and accounting.
What a billing-ERP connector costs in 2026
Price depends on how open both systems are (standard API or file export/import) and the number of objects to sync. A modern billing tool with a REST API is cheaper to connect than a closed solution.
| Item | 2026 range (FCFA) | Note |
|---|---|---|
| Scoping & accounting mapping | 400,000 - 1,000,000 | Chart of accounts, VAT rules |
| Invoices & payments connector | 1,500,000 - 4,000,000 | Two-way sync |
| Automatic accounting entries | 800,000 - 2,500,000 | Generation, reconciliation |
| Webhooks & error recovery | 500,000 - 1,500,000 | Replay queue, alerts |
| Testing & go-live | 400,000 - 1,200,000 | Tests on real data |
| Annual maintenance | 12 - 15 % /year | Monitoring, API changes |
Webhooks with error recovery are not optional: without them, a network incident can lose an invoice between the two systems.
Synced flows and accounting hours saved
Each automated flow removes a re-entry and its error risk. Here are the priority flows and their impact on the accounting team.
| Flow | Direction | Accounting hours/month saved |
|---|---|---|
| Issued invoices → ERP | Billing → ERP | 15 - 30 |
| Received payments → reconciliation | Billing → ERP | 10 - 20 |
| Automatic accounting entries | Billing → ERP | 12 - 25 |
| Credit notes & cancellations | Two-way | 5 - 12 |
| Customers & third-party accounts | ERP → Billing | 4 - 10 |
| Assisted bank reconciliation | ERP | 8 - 18 |
Combined, these lines often free 50 to 90 accounting hours per month — half a full-time role redeployed to analysis.
Mini case study
Mr Koné, CFO of a 70-employee trading SME in Abidjan, sets up a connector at 6 million FCFA build plus 12 % maintenance (720,000 FCFA/year). Before, two accountants spent 70 h/month re-entering invoices, payments and entries; at a loaded cost of 4,500 FCFA/h, that was 315,000 FCFA/month, i.e. 3.78 million FCFA/year. Removing 85 % of that load (about 3.2 million FCFA/year), the connector pays back in about 21 months, then delivers over 2.4 million FCFA/year net gain — before counting the end of period-close discrepancies.

FAQ
How long to install a connector?
Expect 4 to 8 weeks in 2026, depending on system openness. A billing tool with a REST API connects faster than a solution needing file imports.
What happens during a network outage?
A serious connector uses webhooks with a replay queue: unprocessed events are replayed automatically once the network returns. No invoice is lost.
Does the connector handle VAT and the local chart of accounts?
Yes, provided the rules are scoped upfront: VAT rates, third-party accounts, reconciliation. This accounting scoping (400,000 to 1,000,000 FCFA) determines entry reliability.
What is the annual maintenance cost?
Between 12 and 15 % of build cost per year, i.e. 360,000 to 1,350,000 FCFA. It covers monitoring and adapting to API updates.
Can you connect an ERP without an open API?
Yes, via scheduled file imports/exports, but the sync is no longer real-time and the budget approaches 9 million FCFA with more testing.
