Debit Note is issued by the purchaser, at the time of returning the goods to the vendor, and the vendor issues a Credit Note to inform that he/she has received the returned goods.
When the goods are returned to the seller or supplier, a debit note is issued to him which indicates that his/her account has been debited with the repective amount. On the other hand, when a customer returns goods, a credit note is issued to him which shows that his account has been credited with the amount indicated in the note.
