When making a sale on GEM-BOOKS, it is possible to assign a finance fee for credit card payments.

ATTENTION: before configuring your GEM-BOOKS, make sure that in your state, province or country, this option is valid within the law, as each location has a specific law that must be respected. The configuration of this finance charge is the responsibility of each client and may vary according to your location and local law. In Canada, we have the following link with more information: Merchant surcharges, service and convenience fees, and discounts.
