What is a credit note?
A credit note, sometimes called a credit note or credit memorandum, is a document that allows you to make changes to an invoice after it has been issued or paid.
When you issue a credit note, you are essentially deleting an amount from an invoice, and your financial records, without deleting the invoice itself.
This is important for record keeping purposes, especially because in many countries you need to keep all invoices for auditing purposes, even if they're incorrect.
Credit notes can also be used to cancel part or all of an invoice for products or services.
For example, if you were to accidentally issue an invoice for $100 instead of $75, you'll then need to issue a credit note for $25 to correct the outstanding balance.
Additionally, if a customer were to cancel their order after you had issued an invoice, you could also use a credit note to cancel the full amount.
