It is possible to reverse the fees and generate a refund to the customer, and we can apply the fee revenue to the customer refund.
Refunding processing fees
1. Go to the payment that you want to refund back the processing fees.
2. Unapply the Fee Revenue.
3. Create a new Refund and apply the Fee Revenue to the created Refund.
You need to look for the transaction with the same amount of the refunded fee revenue.
Once this refund has been created in Netsuite, the payer will receive the funds within 24 to 48 hours.
