What Is a Credit Note?
A credit note (or credit memo) is a document a seller issues to a buyer stating that an amount has been credited to the buyer's account, reducing what they owe. It's used to correct an overcharge, process a return, or apply a discount after an invoice has been issued.
What a credit note is and why it matters
A credit note is effectively a negative invoice. Because you can't simply delete an issued invoice without breaking the audit trail, a credit note is the proper way to reverse or reduce a charge — it documents why the adjustment happened and keeps records clean. It reduces the seller's accounts receivable and revenue, and lowers the buyer's payable. Common triggers include returned goods, billing errors, damaged shipments, or a negotiated price reduction. Tracking credit notes matters for accurate revenue and for a receivables ledger that reflects reality.
A worked example
A supplier invoices a customer $5,000, but the customer returns $800 of defective product. Rather than editing the original invoice, the supplier issues a credit note for $800. It records: debit *Sales Returns* (or Revenue) $800, credit *Accounts Receivable* $800. The customer's outstanding balance drops from $5,000 to $4,200, and the paperwork shows exactly why.
How firms handle it today
Firms issue credit notes through the accounting software, matching each to its original invoice so receivables and revenue stay accurate and the reason for every adjustment is documented.

FAQ
What's the difference between a credit note and an invoice?
An invoice bills a customer for what they owe; a credit note reduces that amount, acting like a negative invoice.

For returns, overcharges, billing errors, damaged goods, or post-invoice discounts.
Why not just delete the original invoice?
Deleting breaks the audit trail. A credit note documents the adjustment and keeps records complete and traceable.
