The verdict in three sentences
In B2B, online payment is not about charging a card instantly: it is about smoothing bank transfers, handling payment terms and automatically reconciling settlements against invoices. In 2026, integrating a multi-method aggregator into a portal costs 2,000,000 to 6,000,000 FCFA (about 3,050-9,150 EUR), with fees of 1.5 to 3.5% by method. The real gain is cash flow: fewer late payments, less chasing time.
B2B payment methods and their fees
A B2B portal must cover several methods because trade buyers don't all behave the same. Here are the 2026 orders of magnitude.
| Payment method | 2026 fee (estimate) | Settlement delay | B2B use |
|---|---|---|---|
| Bank transfer | 0 - 0.5% (fixed fees) | 1 - 3 days | Large orders |
| Digital wallet (Wave, Orange Money) | 1 - 2% | Instant | Mid-size orders |
| Card | 2.5 - 3.5% | 1 - 2 days | International clients |
| Payment terms (30-60 days) | Handled internally (credit) | Deferred | Recurring clients |
| Recurring direct debit | 1 - 2% | Per schedule | Subscriptions, restock |
The right B2B reflex: favour transfer and wallet to minimise fees on large amounts, and reserve card for clients who require it.
What the integration includes
The cost is not just plugging in a gateway. The value is in automation.
| Line item | Content | 2026 order of magnitude |
|---|---|---|
| Multi-method aggregator | Single gateway transfer/wallet/card | 800,000 - 2,000,000 FCFA |
| Automatic reconciliation | Matching payment / invoice | 600,000 - 1,800,000 FCFA |
| Credit management | Ceiling, block, reminders | 400,000 - 1,200,000 FCFA |
| Invoicing and receipts | Automatic issuance, PDF | 300,000 - 1,000,000 FCFA |
| Webhooks and security | Confirmation, tests, logging | Included / 200,000 - 600,000 FCFA |
| Total integration | 2,000,000 - 6,000,000 FCFA |
Automatic reconciliation is the most cost-effective item: it removes manual matching of settlements, a source of errors and delayed closes.
The ROI is a cash-flow ROI
B2B online payment pays for itself by cutting the average payment delay (DSO) and chasing time.
| Metric | Before | After integration (estimate) |
|---|---|---|
| Days sales outstanding (DSO) | 52 days | 36 days |
| Late payments | 28% of invoices | 19% (-30%) |
| Chasing time / month | 22 h | 7 h |
| Reconciliation errors | 8% | under 1% |
| Settlements outside hours | 0% | 30% |
A 16-day DSO reduction on 400,000,000 FCFA/year of revenue permanently frees up about 17,500,000 FCFA of cash.

Aminata runs a B2B hygiene-products distribution SME in Dubai, 380,000,000 FCFA/year revenue, 50-day DSO. She integrates online payment for 4,200,000 FCFA: transfer, digital wallets, card, payment terms and automatic reconciliation.
Six months later, DSO drops to 36 days. Those 14 days gained on 380,000,000 FCFA represent 14,580,000 FCFA of freed cash (380M x 14/365). Chasing time falls from 22 h to 7 h/month, saving 15 h per month. The integration pays back in cash flow within the first year, before even counting fewer late payments.
FAQ
Why integrate payment if my clients already pay by transfer?
Because transfer alone leaves manual matching, a source of delays and errors. Integration automates reconciliation, sends receipts and manages credit: that is where the cash-flow gain hides.
What fees should I expect in 2026?
Allow 0 to 0.5% on transfer, 1 to 2% on wallets, 2.5 to 3.5% on card. For high-value B2B, steer clients to transfer and wallets to control cost.
Can payment terms be managed automatically?
Yes: the portal applies a per-client credit ceiling, blocks orders beyond it, issues the invoice at due date and chases automatically. It is the most structural B2B function for cash flow.
How long does integration take?
Between 4 and 8 weeks depending on the number of payment methods and reconciliation complexity. The key factor is access to your bank's and the aggregator's APIs.
Is it secure?
Yes, if the integration respects confirmation webhooks, logging and end-to-end tests. Never validate an order on a mere browser callback: only the provider's server confirmation counts.
