What kind of payment surcharges can I add with this extension?

You can add as many different surcharges as you like based on your store's payment methods - including credit cards, Paypal, Stripe, bank transfer, check, Afterpay and more.

You can't yet add different surcharges for different credit card types (e.g. 5% for AMEX but only 3% for Visa/Mastercard). This feature is on our roadmap for future development.

Based on our experience with Magento 1 and surcharges, certain custom payment methods (those which send cart contents but do not honour Magento custom totals like surcharges) may not be compatible with Fooman Payment Surcharge. Our extensions include a 30 day money back guarantee, so feel free to test out the extension with any custom payment method if you suspect it may not not honour Magento custom totals.
