How can I accurately calculate a return voucher for accounting?

[DaphneOlive]

Does anyone have advice on how to approximate a return voucher? For the sake of our accountant, we make sure that our vouchers and credit card charges match. Which I think means that the shopify PO system of rejecting items from a PO (if damaged or missing) won't work for us. We need for the received PO (I am going to miss vouchers, but I have accepted that part of my fate) must reflect the cc payment, and we need to be able to create a credit separately that would match the refund or credit with the vendor that we will receive. 

side note - why I will miss vouchers? Because one PO can end up getting shipped to us in multiple shipments, each with its own invoice, credit card payment, and information. We have created a messy workaround for that part, but I have not figured out a workaround for needing return vouchers that feels right

since I wrote this, we realized that Stocky does allow negative quantities in POs, which I assume will do the trick. I am not sure if I missed it earlier or if it is a new feature. Either way, All good
