The original service fees are not returned when refunding an order in full or partially. (Exception: No service fees applied to a voided transaction). 

For Organizations Who Have the Customer Pay the Service Fees:

When doing a cancellation & refunding, the admin is given an option to refund the fees to the customer YES OR NO. 

If YES:  The service fee paid by the customer will be refunded to the customer. The organization will absorb those fees. 

If NO: The service fee paid by the customer will NOT be refunded to the customer. The customer will absorb those fees.

For Organizations Pay the Service Fees:

When doing a cancellation & refunding, the admin is given an option to change the amount of the refund. 

If the admin wants the customer to receive their full refund, they should keep the full amount listed. The organization will absorb the original service fee but the customer will receive a full refund.

If the admin wants the customer to receive a refund minus the original service fee, they should calculate that amount and enter the correct amount of the refund in the highlighted box. This would mean the organization did not absorb any fees on the refund.
