WooCommerce Payment Gateway Based Fees
Add fees to orders based on payment method
The Payment Gateway Based Fees extension enables you to add a fee to an order, depending on the chosen payment gateway.
The fee can be automatically assessed on the price of certain products in the cart or the cart total, in addition to being changed on an order by the shop administrator at any time. A fee may also be applied manually, i.e., if the customer wants to switch payment methods after checkout is completed.
