What is the purpose of a credit note?

A credit note records an approved reduction or correction to an earlier customer invoice while preserving the original document. It usually states the amount, reason and invoice reference so the adjusted balance can be explained. Typical causes include returns, cancellations, overcharges and post-invoice concessions. The exact document and tax requirements depend on the transaction and jurisdiction.

Is a credit note the same as a refund?

No. A credit note adjusts the documented amount owed by or credited to the customer. A refund is money returned. If the invoice is still open, the credit may simply reduce its balance. If the customer already paid, the business may need a separate refund or application decision. Retain both the adjustment document and payment evidence.

Should an incorrect invoice be deleted instead?

Usually, preserving the issued invoice and linking an authorised correction creates a clearer history than silently deleting or overwriting it. The correct process depends on document state and applicable rules: an unsent draft may be editable, while an issued invoice may require a credit note or other formal treatment. Record what changed, why, when and who approved it.

What should a credit note reference?

It should normally carry its own identifier and date, reference the original invoice, identify the seller and customer, describe the affected goods or services, state the reason and adjustment amount, and include applicable currency and tax information. Requirements vary, so confirm the official rules for the transaction rather than relying only on a generic template.

How does a credit note affect accounts receivable?

A valid credit note generally reduces the related open customer balance by its approved amount. The record should retain the original invoice total, the linked credit and the remaining amount separately. If payment was already received, finance must also decide whether to refund, apply or otherwise resolve the customer credit and retain the matching evidence.

When is a credit note used?

Common reasons include returned goods, cancelled services, an overcharge, an agreed discount after invoicing or correction of quantity, price or tax detail. The adjustment should follow the actual commercial event and approval authority.

Do not delete or overwrite the original invoice merely to make the total look right. Linking the credit note preserves what was issued, what changed and why.

Return or cancellation
Overcharge or quantity correction
Post-invoice concession
Approved tax or document correction

Start with the original record in what is an invoice.

What information should it contain?

A useful credit note identifies the seller and customer, carries its own document number and date, references the original invoice, describes the affected lines, states the amount and reason, and shows relevant tax detail where required.

Requirements vary by jurisdiction. Confirm the current rule for the transaction rather than treating a general field list as legal advice.

Unique credit-note number and date
Original invoice reference
Reason and affected items
Amount, currency and applicable tax detail
Approval and delivery evidence

Use the structured fields in the credit note template.

Credit note, refund and cancellation

A credit note adjusts the documented customer balance. A refund is the return of money. They may be connected when a customer already paid, but one does not prove the other occurred.

Cancellation describes the commercial event and may require a credit note, void treatment or another process depending on timing and rules. Retain the document state and payment event separately.

Credit note: balance adjustment document.
Refund: money returned.
Cancellation: commercial event requiring the appropriate record.

Compare direction and use with a debit note.

Credit note versus debit note

In a seller-to-customer invoice context, a seller-issued credit note generally reduces the customer amount. ‘Debit note’ can have different direction and usage by jurisdiction or party, so the issuer and underlying event must be clear.

Do not infer the effect from the document name alone. State who issued it, which original record it references and whether the open customer balance increases or decreases.

Identify issuer and recipient.
Reference the original invoice.
State the direction of adjustment.
Confirm jurisdiction-specific requirements.

Keep linked records visible through invoice management.

Worked example: partial reduction

A seller issued a $5,000 invoice containing 20 service units at $250. Two units were included in error. A credit note for $500 references the original invoice and records the correction.

If no payment has been matched, the open customer balance becomes $4,500. If the customer already paid $5,000, the credit note establishes the adjustment but a separate refund or application decision is still required.

Original invoice: $5,000
Incorrect units: 2 × $250
Credit note: $500
Adjusted balance: $4,500

Follow the adjusted balance in accounts receivable.
