Use a sales return order to return the stock to inventory (because you technically are, even for only a short while). Then you can dispose of it with an item journal and a negative adjustment.
You could also just issue a manual credit to the customer if you want to skip all of that. Depends on what level of detail you want.
Use SRO as intended (create it with CopyDocument function, that’s easier) and you have such options before posting it:
change line type to GL Acc and choose corresponding account for ‘returned damaged merchandise expenses’ you will need to refill Qty, Amt, etc etc.
leave your Item as is but change location to “Returned merchandise” and decide later what to do with it - resell if good, repair, write off.
the second option for you is theoretical, your tile is returned because broken, but you can use this approach if you offer money-back period or item broke until under warranty.
in both cases Customer’s balance is properly updated, but in first case Item “vaporized” without trace, which not always is the best method, depends on your business practice.
