  • With the payfac model, you hold a master merchant account with us and each sub-merchant is issued a Merchant ID in our system.
  • Through our API your sub-merchants are boarded and ready to process instantly once they click ACCEPT on the terms and conditions documents which will be emailed to them.
  • Everything is hosted on your site through our secure iFrame so there is no interaction with us and the customer experience remains within your platform.
