If you are using the Return Merchandise Authorization feature of Shift4Shop, you can review your store's RMA history with the RMA search tool located in your Orders menu.
RMA Search
To get to the RMA search, go to Orders > Manage Returns.
If your store does not have any open or pending RMA entries to process, the RMA search page will likely be blank. However, you can filter the default view to see your store's history.
To do this, click on the Advanced button located at the top of the screen (next to the search bar).
Then select All for RMA Status and click Search.
You can also filter your search by the other parameters as needed including the First Name/Last Name (of the customer), their email address, and RMA number.
