The Complete Gateway is an online terminal that facilitates the acceptance of credit card and ACH transactions.  The gateway is also built to integrate with several POS systems including shopping carts through an API or Source Key.  

This article will focus on how to run a Refund transaction within the Complete Gateway.  

Once logged into the Complete Gateway you will find a series of tabs listed below the CG (Complete Gateway) banner on the screen. A Refund transaction can be made when selecting the Search tab.  To search for the transaction that you would like to refund, perform a search with some information about the transaction.  This could be something like the dollar amount, customers name, customers address, or the last four digits of the card number.

Once the transaction is found select the details button to the right of the transaction.

When viewing the details of the transaction you will find the Transaction Results, Transaction Information, Transaction Source, Billing Information, etc.  On the right hand side of your screen you will see two boxes, one listed as Quick Credit and another listed as Quick Sale.  To perform a refund on the credit card adjust the amount in the Quick Credit box to the amount that is needed to be refund.  Once adjusted select the Credit button to perform the refund.  

A confirmation of the Refund will appear with the option to confirm the refund in the open batch.
