Issue a credit note
Returns and corrections against a sales invoice.
A credit note reduces what a customer owes. It is linked to the original invoice, so both appear together in the customer's history.
Open the original invoice
Find the submitted sales invoice you want to correct.
Create the return
Select Create, then Return / Credit Note. A new invoice opens with Is Return (Credit Note) ticked and Return Against set to the original.
Adjust the quantities
Keep only the items and quantities being returned or credited. Quantities show as negative.
Submit
Select Save, then Submit. The customer balance goes down, and returned stock goes back to the warehouse if stock was updated.
Refund or offset
Refund the customer with a payment entry, or leave the credit to be used against their next invoice.
