Invoice vs. Cash Memo: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 5, 2023
An "Invoice" is a request for payment detailing goods or services provided, while a "Cash Memo" is a confirmation of a cash transaction.

Key Differences

An "Invoice" is a detailed bill presented by a seller to a buyer, outlining the products or services sold, their quantities, prices, and terms of payment. It essentially acts as a credit instrument, indicating that the buyer owes the seller money. In contrast, a "Cash Memo" is issued by the seller when a cash transaction takes place. It confirms that the payment has been received in cash for the goods or services provided.
The primary function of an "Invoice" is to request payment. It is typically issued in scenarios where goods or services are provided on credit, and payment is expected in the future. The "Cash Memo", however, serves as evidence that a cash transaction has occurred, signifying immediate payment.
While an "Invoice" is a formal request that gives a breakdown of the transaction, including the total amount due, taxes, and other charges, a "Cash Memo" is a straightforward acknowledgment of cash received. The "Cash Memo" might not be as detailed as an invoice but confirms the completion of a transaction.
Businesses frequently use "Invoices" to keep track of their accounts receivable, ensuring that they receive all the payments due to them. The "Cash Memo", on the other hand, aids in monitoring and recording instant cash transactions, assisting businesses in managing their daily cash flow.
