A credit note is effectively a negative invoice - it's a way of showing a customer that they don't have to pay the full amount of an invoice. A credit note might either cancel an invoice out completely if it’s for the same amount as the invoice, or it might be for less than the invoice.
You might issue a credit note to your customer if:
- your customer wasn’t happy with your service and you’re giving them a full or partial refund
- you overcharged your customer by mistake
- you issued an invoice by mistake and are happy that your customer doesn’t have to pay
