Customer is using Serial Inventory and sells new and used equipment. They will receive in the inventory at $100/each but find afterwards that some of the items are bad, doa, etc. They work with the vendor and agree to a $20/each discount (let's say 2 of 10 are bad, credit is for 2). Because it happens a lot, they don't want to return the PO and Receive it again at the lower price. I suggested taking the credit directly to COGS but Mgmt wants inventory adjusted (have cake and eat it!). Anybody have any suggestions on how to accomplish this?
