Magento 2 Payment Fee
Payment Fee extension for Magento 2 allows adding extra charges for specific payment methods and displays them on the cart page, checkout page, invoice, and credit memo. Also, payment fees display in the sales email like new order, invoice, and credit memo. Admin can also set the payment fee in order creation from admin.
According to the payment method, there are several options for counting payment fees by percentage price, fixed price, per row and per item. The payment fee title and description are configurable from admin. Payment fees can be disabled after a specified maximum order amount. You can set the payment fee is refundable or not from the configurations settings. You can also set a default payment fee which acts as an extra fee on order.
