For each payment method in your store, a fee can be added that will appear at checkout. It can be a percentage of an order or a fixed amount. Once a customer selects the payment method with the extra fee during checkout, the surcharge is added to the order total (after all discounts).
This can assist in covering payment-specific fees. For example, transactional fees charged by your payment gateway or additional fee charged by your Cash on Delivery service.
The fee always has your store’s standard tax rate applied to it, even if a product itself has a special tax rate. In addition to checkout, the fee is shown in customer order notifications, invoices, and order details.
Add a fee to a payment method
To add a fee to a payment method:
In the side panel, click eCommerce, and then click Manage Store.
In the Configuration section, click Payment.
If you already have payment methods set up, select the one that you would like a fee added to. If no payment methods are set up, see Online Payments (Third Party Store) or Offline Payments (Third Party Store).
In the Payment method fee section, click Add payment method fee.
Enter the amount you want to charge. To charge a percentage instead of a flat amount, click on the dropdown and select the percentage symbol (%).
(Optional) In the Payment instructions for customers section, add an explanation about why you charge fees. Customers will see your additional note at checkout.
