How do I resolve an incorrect customer invoice?

If you’ve issued an invoice with the wrong amount or details, the correct way to fix it is to create a credit note.

Due to bookkeeping and audit requirements, invoices cannot be edited or deleted once they’ve been sent—doing so would break the chronological and traceable record that financial reporting relies on. A credit note reverses the original invoice in a compliant and transparent way.

After creating the credit note, you can then issue a new, corrected invoice if needed.
