The verdict in three sentences
An API integration between your web app and your ERP costs in 2026 from 3,000,000 FCFA (simple connector, batch sync) to 12,000,000 FCFA (real-time middleware, multi-module). The price is driven mainly by the number of data flows, the data volume, and whether you need real-time. Budget 4 to 10 weeks for the project and 15%/year maintenance to absorb your ERP's evolutions.
What moves the bill
An ERP connector is never a single flat fee: it is composed. The starting point is the ERP type (SAP, Odoo, Sage, Dynamics), how rich its API is, and how many objects you must sync (customers, items, orders, stock, accounting entries). A modern ERP with a documented REST API lowers the bill; a legacy ERP forces middleware and data transformation.
The second factor is the sync mode. Batch (every X hours) is robust and cheap; real-time via webhooks demands error handling, queues, and idempotency, which raises the budget.
| Integration scenario | Synced flows | Mode | Timeline | 2026 cost (FCFA) |
|---|---|---|---|---|
| Simple connector | 1-2 (customers, items) | Nightly batch | 4 weeks | 3,000,000 - 4,500,000 |
| Standard connector | 3-4 (+ orders, stock) | Hourly batch | 6 weeks | 5,000,000 - 7,000,000 |
| Advanced integration | 5-6 (+ accounting, delivery) | Partial real-time | 8 weeks | 7,500,000 - 10,000,000 |
| Full middleware | 7+ bidirectional | Real-time + queues | 10 weeks | 10,000,000 - 12,000,000 |
Detailed cost breakdown
Getting into the detail avoids nasty surprises. Here is the breakdown of a standard connector at 6,000,000 FCFA.
| Line item | Share of budget | Amount (FCFA) |
|---|---|---|
| Scoping and field mapping | 15% | 900,000 |
| API connector development | 40% | 2,400,000 |
| Error handling and reconciliation | 20% | 1,200,000 |
| End-to-end testing and acceptance | 15% | 900,000 |
| Documentation and handover | 10% | 600,000 |
On top of this comes annual maintenance: 15% of the initial cost, i.e. 900,000 FCFA/year for this project, covering ERP-side API changes, new fields, and flow monitoring.

Mini case study
Mr. Fotso, IT director of a distribution company in Douala, wants to connect his field order-taking app to his Odoo ERP. Three flows: items/prices (ERP to app), stock (ERP to app), orders (app to ERP). He picks hourly batch sync, i.e. a standard connector at 6,000,000 FCFA, 6-week timeline.
Before integration, 4 people re-keyed orders into the ERP, roughly 60 hours/month combined at 2,500 FCFA/h loaded cost, i.e. 150,000 FCFA/month of data entry, not counting errors. The integration removes this double entry. Annual saving: 1,800,000 FCFA, plus reliability. Payback in a little over 3 years on data entry alone, far faster once you count avoided errors and reduced stockouts.
FAQ
How much is the cheapest connector? A single-flow connector in batch sync starts around 3,000,000 FCFA in 2026. That is enough to sync an item catalogue or a customer base, without real-time.
Real-time or batch: what is the premium? Moving from batch to real-time adds roughly 30 to 50% to the connector budget, because you need webhooks, queues, and idempotency handling to avoid duplicates.
What timeline should I expect? Budget 4 weeks for a simple connector and up to 10 weeks for a full bidirectional middleware, acceptance testing included.
What does the 15%/year maintenance cover? It funds adapting to ERP updates, adding fields, monitoring flows, and fixing sync errors. On a 6,000,000 FCFA project, that is 900,000 FCFA/year.
Can several ERPs or apps be integrated? Yes, via a central middleware orchestrating multiple connectors. The budget then climbs toward the top of the range, 10,000,000 to 12,000,000 FCFA, depending on the number of systems.
