    • Return of goods: If the buyer returns defective or excess goods to the seller.
    • Overcharged: If the buyer was charged more than the actual price of goods or services.

  • It acts as a request for a credit adjustment to the seller’s account.

Credit Note:

  • Conversely, a credit note is issued by the seller to the buyer when there’s a decrease in the amount payable by the buyer. It is a document that notifies the buyer that the seller’s account has been credited (decreased) due to various reasons such as:
    • Goods returned: Acknowledging the return of goods by the buyer.
    • Overpayment: If the buyer paid more than the actual price for goods or services.
