To the customer, BNPL feels like a payment method — click, split into installments, done. Behind the checkout button, it's closer to a real-time lending decision made in the time it takes a page to load.
Who's actually extending the credit
The merchant gets paid in full, upfront, just like any other transaction. It's the BNPL provider that fronts the money and takes on the risk of the customer paying their installments late or not at all — which is also why they charge merchants a higher fee than a typical card transaction.
The underwriting happens instantly, not eventually
Behind that quick approval is a real credit decision, just compressed into seconds using data the provider already has instead of a traditional application. That's why some legitimate customers get instantly approved and others get instantly declined, with no visible explanation either way.
What changes on your side of the integration
Refunds and disputes get more complex because the money already moved through a third party who's still owed their installments regardless of what happens with the underlying order — a partial refund on a BNPL order isn't as simple as reversing a normal card charge.
Key takeaways
- The merchant is paid in full upfront; the BNPL provider carries the repayment risk.
- BNPL approval is a real-time credit decision, not a simple payment method choice.
- Fees are higher than standard cards because the provider is also underwriting risk.
- Refunds on BNPL orders need to account for the installment structure underneath.
