Partial refunds are usually used to refund an order that has a credit due.
You can make a partial refund on a payment, if you have the approriate permissions. Partial refunds apply to local payments (cash, cheque, account) and reconciled credit/debit charges. To make a full refund, refer to Refunding a Payment.
To partially refund a payment:
1.Open Customer Services from the Desktop.
2.Select the Order tab.
The Order|Search page appears.
3.Search for and select the order that you want to work with.
The Order|Summary page appears.
4.Expand the payment that you want to partially refund.
5.Click 'Partial Refund'.
This button is only available if the order is overpaid, and displays a negative amount in the 'Amount Due' field.
An Unprocessed Refund is added to the order. By default, the refund amount and payment information match the original payment. If you need to confirm or modify the details, click 'Update Payment'. You cannot modify the payment method, but you can also refund a payment using a different payment method.
6.Click 'Apply'.
A window confirms that the order was updated.
7.Click 'OK'.
The payment changes from Unprocessed Refund to Refund. The original payment remains on the order.
If necessary, you can cancel or void a refund.
