Free Credit Note Generator
A credit note cancels all or part of a previous invoice. It must reference the original invoice number — without that reference it is not a valid adjustment for tax purposes.
What to include on a credit note
- Always reference the original invoice number and date. Tax authorities require the link.
- Never edit an issued invoice. Issue a credit note and a new invoice instead — editing destroys the audit trail.
- Show the tax adjustment separately, otherwise your VAT/GST return will not reconcile.
How it works
- 1. Fill in the form. Add your details, the client, and each line item with quantity and rate.
- 2. Check the totals. Tax and discount update as you type — nothing is stored or submitted.
- 3. Download the PDF. A print-ready A4 document is generated in your browser and saved directly to your device.

Frequently asked questions
When should I use a credit note?
For returns, overpayments, pricing errors or cancelled services after an invoice was already issued.
Does a credit note reduce my sales tax?
Yes, if it references the original invoice and shows the tax adjustment. It reduces your taxable turnover for the period.
Can I just delete the original invoice?
No. Issued invoices must stay in your sequence. Credit notes preserve the audit trail.
