You are receiving an error that says "CustomerCode is required".

  • The Customer Code is the unique identifier that is associated with the customer of an invoice/sales order/ quote.
  • This is required since it is the key to the Exemption Certificate Management Service in the Admin Console.
  • Please review your transaction to make sure that a customer is selected.
