A Credit Note is a formal legal accounting document issued by a seller to a buyer to reduce the amount owed from a previously issued invoice.

Common Scenarios for Credit Notes

  • Returned Products: A buyer returns damaged or incorrect merchandise.
  • Invoice Overcharging: An error occurred in original item pricing or quantity.
  • Post-Sale Discounts: Additional volume discounts agreed after invoice issuance.
  • Order Cancellation: Part or all of a billed service order was canceled.

Frequently Asked Questions

Why should I issue a Credit Note instead of altering an existing invoice?

Altering or deleting paid or filed tax invoices creates audit discrepancies. Issuing a sequential Credit Note provides an audit trail for refund adjustments.
