How do I refund or correct an invoice?
Refund or credit note; admins can delete a mistake.
On the Invoices tab, open the invoice and use Refund or Credit note. Credit notes are numbered and listed under Credit notes, and the accounts are updated.
An invoice made by mistake can be deleted by an admin with Delete if it has no card payment or credit note and its period is not locked. If it was the newest invoice, its number is used again.
