Charge customers for using specific payment methods
The extension adds an extra fee to cart (order) totals when customers switch a certain payment method when placing an order.
Fixed and percentage fee types
You can create an unlimited number of payment fees. The fees can have both "fixed" and "percent" amount types. So you can apply combined charges. For example, you can configure 2,9% + $0.30 for PayPal.
Flexible tax settings
You can configure the extension to calculate tax separately for payment fees. In this case, you’ll be able to set a tax class to be applied to the fees. There is also a setting which allows displaying the fees excluding and/or including tax.
