Surcharges

Surcharges are not supported by default.

Applying surcharges with third-party extensions

To apply a surcharge or payment fee to a payment method, you can use the third-party extensions .

Attention Dutch merchants

We strongly recommend not applying surcharges to BNPL methods. This is now considered providing credit under the Wet op het consumentenkrediet and article 7:57 of the Burgerlijk Wetboek, and requires a permit from the Authority for Financial Markets (AFM).
