The verdict in three sentences
A supplier extranet for the supply chain costs between 9,000,000 and 22,000,000 FCFA in 2026 depending on the number of connected suppliers, the exchange mode (portal, EDI or API) and the depth of ERP integration. Expect a 4 to 8 month project and 200,000 to 450,000 FCFA/month in maintenance. ROI comes mostly from keying-error reduction and faster order-to-delivery-to-invoice cycles.
The modules and their cost in 2026
Complexity depends on the automation level targeted: a simple entry portal costs less than bidirectional EDI/API exchange with the ERP. 2026 ranges (order of magnitude, regional provider).
| Module | Range FCFA | Timeline |
|---|---|---|
| Supplier portal + accounts | 1,500,000 - 3,500,000 | 4-6 wks |
| Order dispatch and acknowledgement | 2,000,000 - 4,500,000 | 4-6 wks |
| ASN (shipping notice) + delivery tracking | 2,500,000 - 5,500,000 | 5-8 wks |
| Invoice submission and matching | 2,000,000 - 4,500,000 | 4-6 wks |
| EDI or API connector | 2,500,000 - 6,000,000 | 6-10 wks |
| ERP integration (orders, receipts) | 3,000,000 - 6,500,000 | 6-10 wks |
| Supplier dashboard + KPIs | 1,500,000 - 3,000,000 | 3-4 wks |
ASN and invoice matching are the modules that remove the most manual re-keying on the procurement and accounting side.
The ROI: times and errors
The gain is measured on three concrete levers. Here are orders of magnitude observed in 2026 after digitisation.
| Lever | Before (manual) | After extranet | Gain |
|---|---|---|---|
| Order keying errors | 6-9% | 1-2% | -75% |
| Invoice processing time | 8-12 days | 2-4 days | -65% |
| Delivery tracking time | 30 min/order | 5 min/order | -80% |
| Supplier disputes / month | 40-60 | 10-15 | -70% |
| Processing cost / order | 4,500 FCFA | 1,500 FCFA | -66% |
These gains compound: fewer errors = fewer disputes = less agent time = better-managed cash.
Mini case study
Mr Sarr, procurement director of a food distributor in Dublin, works with 75 suppliers and processes 2,200 orders/month by hand, with 7% errors. A 16,000,000 FCFA extranet (portal + ASN + ERP integration) brings processing cost from 4,500 to 1,500 FCFA per order. After realistic team reallocation, the net gain is 7,000,000 to 9,000,000 FCFA/year. Payback in about 24 months.

FAQ
EDI or API: which to choose?
API suits modern suppliers and costs 2,500,000 to 6,000,000 FCFA. EDI remains useful for legacy large accounts. You can start with an entry portal and add EDI/API in Phase 2.
How many suppliers can we connect?
There is no technical limit. The portal handles 20 to several hundred suppliers; only onboarding (training, accounts) takes time.
What gain on keying errors?
Generally from 6-9% to 1-2%, about -75%. It is the item that most reduces disputes and credit notes to issue.
Must we integrate the ERP from the start?
Not necessarily. A standalone portal already creates value. ERP integration (3,000,000 to 6,500,000 FCFA) is added in Phase 2 to remove double entry.
What maintenance budget?
Between 200,000 and 450,000 FCFA/month: hosting, monitoring, fixes, enhancements and supplier support.
