The verdict in three sentences
Integrating online payment costs between 2,000 and 6,000 EUR in 2026 for a simple PSP connection, and 8,000 to 20,000 EUR for multi-method (card, mobile money, transfer). But the real recurring cost is fees: 1.4 to 2.9% + 0.25 EUR per card transaction, 1 to 2.5% for mobile money. Your PSP choice depends first on target markets and average basket, not on integration price.
Integration cost: simple vs multi-method
Development depends on the number of payment methods, required compliance and expected accounting reconciliation. Here are the 2026 ranges.
| Scope | Contents | 2026 order of magnitude |
|---|---|---|
| Simple PSP (card) | Stripe/Adyen, 1 currency, webhooks | 2,000 - 6,000 EUR |
| Multi-method | Card + mobile money + transfer | 8,000 - 20,000 EUR |
| Reconciliation | Accounting export, statuses, disputes | 3,000 - 9,000 EUR |
| PCI-DSS / 3DS compliance | SAQ-A, 3D Secure v2, tokenization | 2,000 - 6,000 EUR |
| Subscriptions & recurrence | Tokens, retries, dunning | 4,000 - 10,000 EUR |
| Multi-currency | FCFA/EUR/USD, rates, rounding | 3,000 - 8,000 EUR |
A card base + confirmation webhooks is enough to start. Multi-method is justified as soon as you sell in West Africa (Wave, Orange Money) or in B2B (transfer, mandate).
Fees: the real cost over time
Development is a one-off cost; fees run on every sale. That is what to optimize first.
| Payment method | 2026 fee | Fixed fee |
|---|---|---|
| European card | 1.4 - 1.9% | + 0.25 EUR |
| Non-EU / business card | 2.5 - 2.9% | + 0.25 EUR |
| Mobile money (Wave, OM) | 1.0 - 2.5% | 0 - 100 FCFA |
| SEPA transfer | 0.20 - 0.80 EUR fixed | — |
| Wallet (PayPal, Apple Pay) | 1.9 - 3.4% | + 0.25-0.35 EUR |
| Chargeback (dispute) | 15 - 25 EUR | per case |
On a 120 EUR average basket at 2% + 0.25 EUR, you pay 2.65 EUR per order. On 10,000 orders/year, that is 26,500 EUR in fees — 3 to 10 times the initial integration cost.

Mini case study
Sarah, head of a medical equipment SME in Nantes, collects 900,000 EUR/year on 6,000 orders. With a PSP at 1.8% + 0.25 EUR, her annual fees reach 17,700 EUR (16,200 EUR + 1,500 EUR fixed fees). By negotiating a 1.5% rate above 800,000 EUR volume and pushing 20% of payments to SEPA transfer (0.50 EUR fixed), she drops to 13,100 EUR/year, saving 4,600 EUR. The multi-method integration that cost 12,000 EUR is recouped in under 3 years by fee savings alone, before counting the conversion gain.
FAQ
How much does a simple payment integration cost in 2026? Between 2,000 and 6,000 EUR for a card PSP connection with confirmation webhooks and one currency. Multi-method rises to 8,000-20,000 EUR.
Are confirmation webhooks essential? Yes, absolutely. Without a webhook you validate an order on an unreliable client-side status: fraud and double-charge risk. It is 1 to 2 days of development included in any serious quote.
Do I have to be PCI-DSS compliant? If you do not store card numbers (redirect or hosted fields), a SAQ-A self-assessment is enough, at low cost. 3D Secure v2 is effectively mandatory in Europe.
Should I offer mobile money? If you sell in West Africa, yes: Wave and Orange Money capture a majority of payments, with fees often below card (1 to 2.5%).
How can I reduce fees? Negotiate a volume-tiered rate, route large baskets to transfer, and enable 3DS to limit chargebacks to 15-25 EUR per dispute.
