Can I refund orders with store credits?
The RMA extension doesn’t deal with a refund itself. It works only with refund requests and is intended to help admins manage them much faster and easier. Everything about creating credit memos and sending money or store credits to customers should be performed by the admin manually via the default Magento functionality (Orders → Credit Memos).
If you don’t have the Store Credit feature in your shop, our Store Credit & Refund extension might be an option.
Since v.2.9.0 autofilling for Credit Memo data according to RMA request data was added to the Pro and Premium versions of the module. Kindly note that the functionality is available as a part of an active product subscription or support subscription.
