For the stored payment methods to work correctly with the plugin, you need to store additional information in the payment methods in Shopware. To do this, go to Settings → Payment Methods and fill in the following fields per payment method in the Custom Fields tab:
DATEV bank or clearing account – If you also want to export payments using our plugin, enter the corresponding clearing account in DATEV here for each payment method.
DATEV debtor account – If you use collective debtors per payment method, enter the debtor account to be used here; otherwise, you can leave this field empty
DATEV payment term in days – The payment term in days for the payment method. During the DATEV export, this value is used to calculate the due date for the associated receivables.
