Is it possible to add a transaction fee on specific payment options? If the customers wants to pay via sumup, add 2% to the total price, but not if the customers pay cash.

Hello!

If you are looking for a direct, integrated way of doing this additional 2% transaction fee when users pay using a specific payment type, I am afraid that there's no such feature.

However, a workaround that I can suggest is via using taxes as the transaction fee. Taxes can be enabled or disabled at any given point in time manually and so you can use it to set a 2% and call it transaction fee. But, their data will be stored on the tax report and might calculate differently since they are seen as taxes in the system.
