Returning items to a supplier consists of two parts:
- Create a Purchase Credit to record the financial details.
- Make stock corrections for items shipped back to supplier.
Purchase credits are essentially the same as a purchase order but will apply a negative amount to the balance you owe to your supplier. The main difference from Purchase Orders is that you cannot add inventory items to a Purchase Credit.
Since stock items cannot be added to purchase credits, you will have to manually type the details of the items as miscellaneous free-text lines.
You will then need to do a manual stock correction from the inventory derail report to indicate the which items are being sent back.
