Debit notes are a form of proof that one business has created a legitimate debit entry in the course of dealing with another business. This might occur when a purchaser returns materials to a supplier and needs to validate the reimbursed amount. In this case, the purchaser issues a debit note reflecting the accounting transaction.

A business might issue a debit note in response to a received credit note. Mistakes (often interest charges and fees) in a sales, purchase or loan invoice might prompt a firm to issue a debit note to help correct the error.

Debit Notes in Transactions

Debit notes and credit notes are almost always involved in business-to-business (B2B) transactions. They correspond to debit and credit entries in accounting logs, which further serve as proof of a prior business transaction. They may also be referred to as debit memos.

Debit notes usually all include the same general information: the date of the note, a serial number, a brief description of the prior business transaction, details of items returned (including sales taxes and reference to invoice) and the signatures of appropriate company authorities.

You are most likely to hear about a debit note following an under-billed invoice. Suppose a supplier shipped $10,000 worth of materials to a client, but only sent an invoice for $9,500. Upon realizing its mistake, the supplier can submit a debit note to its client for the difference of $500 to resolve the issue and make any proper adjustments to its accounting records.

Debit Receipts

There is some ambiguity between the terms "debit note" and "debit receipt." Sometimes a debit receipt is used interchangeably with debit note – other times, debit receipts are meant only to describe written records that prove a customer owes money to a company. It is rare to see the term debit receipt used for B2B transactions.


A debit note or debit receipt is very similar to an invoice. The main difference is that invoices always show a sale, where debit notes and debit receipts reflect adjustments or returns on transactions that have already taken place.

Debit notes can also be substituted for traditional invoices when a good or service is provided that is outside of the normal scope of business. This helps distinguish the transaction for both accounting departments, and also keeps the issuing company from creating a new type of invoice.

Material Returns

Think of debit notes as claims against business errors. In the case of returned goods from a purchaser to a vendor or supplier, the debit note shows the change in the purchaser books (accounting logs) and requests returned credit. The supplier/vendor often sends a credit note as proof of the reversal.

For instance, consider the case where company XYZ returns material to its supplier, company ABC. To prove the amount it should be reimbursed, XYZ drafts a debit note. The original purchase was for $5,000, so the debit note should reflect the cost of materials, plus local sales tax rates. The taxes and cost of goods should always be separate line items in the note.

Upon receipt, ABC should create a small credit note as proof of understanding, then proceed to reimburse (or offer credit to) XYZ (so long as the debit note contained correct information).

Interest/Commission Receivable

Suppose one business owes interest to a creditor or commission to a third party for services rendered. In such a case, the debit note is normally issued to respond to a received credit note, but a debtor could always issue one unprompted.

Commission receivable debit notes are common between parent companies and subsidiaries. Interest receivable debit notes can be used to adjust prior payments or as a simple form of record keeping.
