I completely agree. Quickbooks needs to make these non-posting credit memos an official credit memo. Work around could be a statement reflecting the unapplied extra monies

1) print current stmt which will show an "unapplied" payment, it DOES NOT show an actual credit memo. Even though when you posted the overpayment or duplicate payment, QB gives you a few options, one of them being "print a credit memo". However again, DOES NOT allow you to assign a credit memo number, which my client and I need to be on same page. If you go into that client to reprint that "credit memo", it is not there, because it was non-posting. all you see is an unapplied payment in the AR and a credit on the customer ledger.  there isn't really anything else you can do from there without doubling up the credit to the customer.

2) other option is a "transaction history" report - but this is not good enough in my eyes for my customers. Only good for me.
