The verdict in three sentences
B2B BNPL (installment payment between businesses) integrates in 2026 for EUR 6,000 to 16,000, with fees of 1.5-4% where the financier carries the default risk and pays you in full upfront. The real lever is not cost but the business effect: +20% to +40% average basket and better conversion on large quotes. The choice comes down to three criteria: financing cap, guarantee of immediate payment and scoring response time.
B2B BNPL offers compared
Here are the 2026 ballpark figures for the main solutions on the French market. Fees are borne by the seller, unless a shared model applies.
| Solution | Seller fee | Typical cap | Seller payment | Integration time |
|---|---|---|---|---|
| Defacto | 1.5 - 3% | up to EUR 100,000 | Upfront, guaranteed | 3-4 weeks |
| Hero | 2 - 4% | up to EUR 50,000 | Upfront, guaranteed | 3-5 weeks |
| Alma Pro | 2 - 4% | up to EUR 30,000 | Upfront | 3-4 weeks |
All shift default risk to the financier: you are paid immediately, the customer repays in 3, 4 or 12 installments. That is the major difference from classic supplier credit where you carry the risk.
Integration cost and ROI
Integration covers the installment payment funnel, real-time scoring, decline handling and status webhooks. Here is the 2026 breakdown.
| Item | Cost (EUR) | Content |
|---|---|---|
| Financier API integration | 3,000 - 6,000 | Connection, scoring, funnel |
| Decline handling + fallback | 1,500 - 3,000 | Switch to card/transfer |
| Webhooks + reconciliation | 1,500 - 3,000 | Statuses, accounting |
| Testing + compliance | 1,000 - 4,000 | End-to-end, edge cases |
On an average quote of EUR 8,000, a BNPL fee of 3% costs EUR 240. If the option converts even 2 extra quotes per month that would otherwise be lost, the margin gain vastly exceeds the fee cost.
Mini case study
Thomas, head of a pro-equipment supplier in Lille, sells batches at a EUR 9,000 average basket, with a 22% conversion rate on quotes. He integrates Defacto for EUR 9,500 at a 2.5% fee. Payment in 4 installments lifts conversion to 30%: on 60 monthly quotes he goes from 13.2 to 18 orders, i.e. +4.8 orders at EUR 9,000. Even after deducting 2.5% fee (EUR 225 per order), those 4.8 extra orders bring about EUR 43,200 of additional revenue per month, minus EUR 1,080 in fees: the integration pays back in the first week of operation.
