A debit note, also known as a debit memo, is issued from a buyer to their seller to request a return of funds due to incorrect or damaged goods, purchase cancellation, or other specified circumstances. A debit note is similar to a credit note, except it’s issued from the buyer's side. Therefore, debit notes are issued before a credit note can be created by the supplier.
A debit note acts as a buyer's formal request for a credit note from the seller. The document serves as evidence to support a purchase return in the accounting books of a buyer.

As a customer, if you purchase goods from a seller or supplier and would like to return the goods for any valid reason, you can issue a debit note.
There are several reasons in which a debit note should be issued. Some common scenarios of when to issue a debit note include:

1) The goods received are damaged or defective
2) The purchaser has been overcharged
3) The invoice value is incorrect (due to extra goods being delivered, or goods are charged at a lesser value, etc.)
