A credit note and a debit note are both accounting documents used to record adjustments to financial transactions. The main difference lies in their purpose and the effect they have on inventory balances in voucher entries 
Credit Note:
Step1: Purpose: A credit note is issued by a seller to a buyer to acknowledge a reduction in the amount owed by the buyer. It is usually issued for various reasons, such as returns, discounts, or overpayments.
Step2: Effect on Inventory Balances: When a credit note is issued for a returned or defective item, it reduces the quantity of inventory on hand. This decrease in inventory is recorded as a credit entry in the inventory account, reducing its value.
