Before you start
You need the appropriate billing permission and a verified reason for the adjustment.
What to do
- Open the original invoice and inspect its status, payments and existing related documents.
- Choose the supported credit, cancellation or correction action offered for that state.
- Review the affected amount, currency, tax treatment and document relationship.
- Confirm the saved result and use a separate delivery or refund process only when required.
What happens next
The original record and the accepted adjustment remain distinguishable in the invoice history.
If something goes wrong
A credit note is not itself proof that money was refunded. Do not delete or rewrite an issued document to hide the original transaction.
