# Raise a credit note

Correct an issued invoice with a credit note, the right way to reduce what a customer owes.

1. Open the issued invoice and select **Raise credit note**.
2. Choose what you're crediting and give a reason, for example "Goodwill: second visit not charged".
3. Save, then issue it.

The credit note gets its own number and reduces what the customer owes on that invoice.

By default, credit notes over **£500 including VAT** need approving first. You can change that in **Settings → Finance**.

A credit note can't be more than what's still owed on the invoice. Refunds of money already paid aren't handled in Sustainable ERP yet.
