Reports and accounting

This: "because quickbooks looks at this as a credit memo and puts products back in stock."

Is why you would not list the original inventory item on the Credit Memo. Make an "RMA Noninventory" type item for that same Product and use this for the Credit Value on the Credit Memo.

Then, use that same item for the Vendor Credit return, as well. That would be a PO.

"quickbooks is limiting us top word template  sheet for returns"

You can make any template of the Credit Memo and the PO with the wording on them to be your RMA process: from customer to you and from you to supplier.
