Payment cost
This section describes how to add an administrative fee to the order for certain payment methods.
Some payment methods may incur additional costs to the merchant. For example, when the payment is by invoice, the printing and postage fees usually need to be added to the order. To add the payment method cost, it needs to be defined in back office Settings > Sales > Payment methods.
Edit the payment method and enter the cost in the Cost (<currency>) field. Note that the VAT % is not used in Sweden. When an end customer selects this payment method, the cost will be automatically added to the order.
