Question

Please answer in full details. i am confused in debit note and credit note.

Answer 1

A debit note is an amount of money (reimbursment) paid by the seller to the buyer of goods or services for which the buyer did not enjoy. normally a slip (debit note) is issued to this effect advising the buyer of the same. a credit is a reverse of this. there are reasons for a debit note.
1. when the goods are substandard.
2. when the buyer overpays the value of the goods.
3. when discount is not properly deducted and has to be paid back to the buyer in cash. etc.
