A debit note increases the amount owed on an invoice already issued — for an undercharge, additional charges or interest. A credit note does the opposite: it reduces or cancels what is owed. Buyers also raise debit notes to notify a supplier of a return or a claim.
A debit note increases what a customer owes on an invoice already sent. The Invoices Tracker keeps your invoices, debit notes and what each client still owes together — so your books always reconcile.
