What is a credit note? Learn what a credit note is, when and why to issue one, what information it must include, and how credit notes work in accounts payable and receivable workflows.
What Is a Credit Note?
A credit note (also called a credit memo or credit memorandum) is a commercial document issued by a seller to a buyer that formally acknowledges a credit on the buyer's account. Its primary purpose is to reduce or cancel an amount previously invoiced — correcting an error, accommodating a return, or applying a post-invoice adjustment. Think of a credit note as the seller's official correction slip: "We billed you incorrectly. Here's the documentation of the adjustment."
When to Issue a Credit Note
A seller should issue a credit note in any of the following situations: Over-invoicing The original invoice was too high — due to a quantity error, pricing error, or calculation mistake. Goods Returned A buyer returned goods and is entitled to a refund or credit. The credit note documents the adjustment. Services Not Delivered Work that was invoiced was not actually performed or delivered. The credit note reverses the charge. Post-Invoice Discount A discount is negotiated or applied after the invoice has already been issued and sent. Rather than voiding the invoice and reissuing, a credit note applies the discount. Invoice Error The wrong customer was invoiced, items were duplicated, or incorrect details were included. The credit note voids the erroneous charge. Bad Debt Write-Off An invoice is deemed uncollectible. The credit note formally writes off the debt and removes it from accounts receivable. Partial Refund A buyer has paid and is entitled to a partial refund for any reason. The credit note documents the refund amount.
What a Credit Note Must Include
A valid credit note contains the following elements: - Seller's business name, address, and contact information - Buyer's billing name and address - Unique credit note number (sequential, for record-keeping) - Date of issue - Reference to the original invoice number being adjusted - Description of the adjustment — what is being credited and why - Credit amount — the monetary value of the credit being applied - Tax adjustment (if applicable) — adjustments to previously collected tax - Remaining balance — the amount the buyer owes after applying the credit

How to Issue a Credit Note
The process for issuing a credit note typically follows these steps: 1. Identify the reason for adjustment — determine whether a credit note is appropriate or whether the invoice should simply be voided and reissued 2. Draft the credit note — include all required fields, reference the original invoice, describe the adjustment clearly 3. Update your accounting records — reduce the customer's accounts receivable by the credit amount 4. Send the credit note to the buyer — with the original invoice reference clearly noted 5. Apply the credit — either to the customer's next invoice, as a refund, or as a standing credit
