# Correct invoices with credit notes

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Required
- Chapter: [Invoices and records](https://agentwranglers.se/playbook/payments/invoices-and-records)
- Rule: Never change or delete an issued invoice. Correct it with a credit note that refers to the original, then issue a new invoice when needed.
- How: Under Article 219 of the VAT Directive, a document that amends an invoice and refers to it clearly counts as an invoice. Give the credit note its own number from the sequence and the original invoice number as a reference. Issue one for each refund or price correction. Keep the data and the PDF of every issued invoice frozen.
- Check: The app's database role cannot UPDATE or DELETE issued invoices. Every refund row in the ledger for an invoiced order has a credit note that refers to an invoice.
