Refunds are applied in the exact same manner as a payment, the only difference is the amount field is entered as a negative i.e. -$125.
To post a refund to a credit card select the desired card from the type drop down in the add payment section.
Then enter the desired refund as a negative amount and apply payment.
For example, to refund $100 you would enter it as -100.00 as shown to the right then click apply payment.
Credit Card Refunds will appear on the Batch Settlement Report as a credit.
