The verdict in three sentences
A custom B2B platform for a wholesaler in West Africa runs between 12,000,000 and 30,000,000 FCFA (roughly 18,300-45,700 EUR) in 2026, depending on catalogue, per-reseller price lists and offline mode. The lever isn't the showcase site but the ordering portal where each reseller finds their net prices, credit and history. Integrated Wave / Orange Money payment and offline mode for low-connectivity zones: ordering moves from the notebook and WhatsApp to self-service.
What a wholesaler expects from a B2B portal
A wholesaler doesn't sell to the public: they supply hundreds of resellers who order in bulk, often on credit, sometimes from markets with unstable connectivity. The portal must therefore handle:
- Per-reseller or per-category pricing (net prices, volume discounts, tiers).
- Credit and deferred payment with a limit per reseller.
- Integrated Wave / Orange Money payment, plus cash on delivery.
- Offline mode: order prepared offline, synced when the network returns.
- Fast reordering: recurring orders, favourite lists, stock alerts.
| Project item | 2026 range (FCFA) |
|---|---|
| Scoping & B2B UX | 1,500,000-3,000,000 |
| Catalogue & per-reseller pricing | 3,000,000-7,000,000 |
| Accounts, credit & instalments | 2,500,000-6,000,000 |
| Wave/OM payment + collection | 2,000,000-5,000,000 |
| Offline mode & mobile app | 2,000,000-6,000,000 |
| Testing & go-live | 1,000,000-3,000,000 |
| Total | 12,000,000-30,000,000 |
The quantified gains
The ROI of a wholesaler portal reads across three axes: order-taking time, reorder rate and errors. 2026 order of magnitude for a wholesaler with 400 resellers.
| Metric | Before (phone/WhatsApp) | After (B2B portal) |
|---|---|---|
| Order-taking time | 15 min/order | 7 min/order (-50%) |
| Monthly reorder rate | Base 100 | +25% |
| Data-entry errors | 6% | 1% |
| Orders outside business hours | ~0 | 30% |
| Collection delay | 20 days | 11 days |
On top of this comes monthly maintenance: budget 150,000 to 400,000 FCFA/month (hosting, evolutions, support) depending on volume.
Mini case study
Aya, director of a food wholesaler in West Africa, manages 400 resellers and 3,200 orders/month. Each order taken by phone ties up 15 min of an agent (loaded cost ~2,500 FCFA/h), i.e. ~625 FCFA/order, or 2,000,000 FCFA/month.
After a portal at 22,000,000 FCFA, 55% of orders move to self-service and processing time drops to 7 min. Saving: 3,200 x 0.55 x (625 - ~290) = ~590,000 FCFA/month of sales time, plus +25% reordering on fast-moving SKUs. Between the time saved and the additional revenue, the investment pays back in 12 to 16 months.
