This app integrates SumUp card terminals into ERPNext and allows card payments directly in the POS.

When a card payment is selected, the amount is sent to a SumUp terminal. After successful payment, the result is sent back to ERPNext and the POS sale is completed.
In the event of a refund or return, the amount will also be automatically refunded for any previous SumUp payments.
