The verdict in three sentences
A dedicated B2B portal — volume-tiered pricing, reseller accounts and recurring orders — replaces WhatsApp order chaos and grows volume per customer. The average B2B basket is 8 to 20 times the consumer basket, so every ordering friction is expensive. For a budget of 1,500,000 to 3,500,000 FCFA (roughly EUR 2,300-5,300), a wholesaler recovers 20 minutes per order and +20 to 35 % reorder frequency.
B2B portal vs a patched-together consumer store
A standard e-commerce store is built for a single buyer who pays immediately. B2B plays by different rules: account-negotiated prices, credit terms, carton quantities, and a buyer who reorders the same SKUs every week. Forcing these onto a B2C store causes pricing errors and a mass return to WhatsApp.
| Criterion | WhatsApp order | Patched B2C store | Dedicated B2B portal |
|---|---|---|---|
| Order capture time | 20-25 min | 10-15 min | < 5 min |
| Volume-tiered pricing | Manual, error-prone | Not native | Automatic |
| Separate reseller accounts | No | No | Yes |
| Supplier credit terms | Verbal | No | 15-30 days configurable |
| One-click reorder | No | No | Yes |
| PDF purchase order export | Manual | Rare | Automatic |
| Observed average basket | Baseline | -10 to -20 % | +20 to +35 % |
Tiered pricing, the engine core
The volume lever is per-tier pricing. The portal automatically shows the applicable rate based on quantity and the logged-in account, with no negotiation each time.
| Tier (units) | Unit price | Discount vs retail | Est. reseller margin |
|---|---|---|---|
| 1-9 (retail) | 1,200 FCFA | — | — |
| 10-49 | 1,020 FCFA | -15 % | ~18 % |
| 50-99 | 900 FCFA | -25 % | ~28 % |
| 100-249 | 840 FCFA | -30 % | ~34 % |
| 250+ | 780 FCFA | -35 % | ~40 % |
Add mobile money (Paystack/Flutterwave, M-Pesa where relevant) for small accounts and bank transfer for large ones, plus 15-30 day terms for loyal resellers: the order fires without a phone call.
Mini case study
Chidi runs a household-goods depot in Lagos. He serves 60 resellers, each ordering 3 times/month on average, average basket 85,000 FCFA. That is 180 orders/month at 25 min each = 75 hours of order capture. After the portal (build 2,400,000 FCFA), time drops to 5 min/order, i.e. 15 hours — 60 hours recovered. More importantly, frequency rises from 3 to 3.9 orders/month (+30 %), i.e. 234 orders. Monthly revenue: from 15,300,000 to 19,890,000 FCFA, a gain of +4,590,000 FCFA/month. The portal pays for itself in under 3 weeks of extra margin.

How much does a B2B portal cost and how long to deliver?
Budget 1,500,000 to 3,500,000 FCFA depending on pricing rules, payment integration and accounting export. Typical timeline: 4 to 8 weeks. A catalogue + tiers + reorder MVP can ship in 3 weeks.
Can we manage supplier credit per reseller?
Yes. Each account has a limit (e.g. 500,000 FCFA) and a term (15-30 days). The portal blocks orders above the limit and auto-reminds at due date, cutting bad debt.
Is mobile money enough for B2B?
For baskets up to ~500,000 FCFA, mobile money covers most cases. Above that, combine bank transfer and term payment. The portal reconciles all three.
What happens to WhatsApp after the portal?
It stays the relationship channel, not the ordering one. Status notifications (confirmed, packed, shipped) go out via WhatsApp/SMS, but entry and pricing live in the portal, error-free.
Does the portal handle recurring orders?
Yes: each reseller sees their history and can reorder their last basket in one click, or schedule a weekly restock. That is the main driver of the +20 to 35 % frequency.
