Compatibility of Payment Surcharge (M2)

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 out of the box. 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. We are also more than happy to take a look at the implementation details of your payment method.
