Example of a funding reject process

  • Funding file is sent to the acquirer
  • The acquirer returns a file of rejected payments
  • The acquirer reviews the reject reason and makes appropriate amendments to merchant details and changes status of an outstanding funding reject
  • Once merchant is amended with the correct detail the status is set to 'Approved'
  • The 'Approved' funding reject is picked up in the institutions next funding cycle, and is resent on the funding file to the acquirer to fund the merchant
  • Funding rejects not 'Approved' can be changed to other statuses so that no further action is required
