How to Create a Credit Note: Steps and Example
Sooner or later, every business needs to fix an invoice that has already been sent. Maybe the price was wrong, the client returned something or the project was cancelled. You should not simply edit or delete the original. The proper tool is a credit note. This guide explains how to create a credit note, what it should contain and how to use it alongside a replacement invoice, so your records stay accurate and your tax paperwork stays in order.
What Is a Credit Note?
A credit note is a document that reduces or cancels the amount on an earlier invoice. It is issued by the seller to the buyer, and it acts as the opposite of an invoice: where an invoice adds to what the client owes, a credit note subtracts from it. Some businesses call it a credit memo or credit invoice.
The key benefit is traceability. The original invoice remains in your records, and the credit note records the adjustment. Anyone reviewing your accounts can follow the trail from the original charge to the correction, which is exactly what accountants and tax authorities want to see.
When to Issue a Credit Note
There are several common reasons.
- Billing errors: wrong quantity, wrong price, wrong client details or a calculation mistake.
- Returns or refunds: the client sends back goods or you refund a service.
- Cancelled work: a project stops before completion and you agree to cancel part or all of the invoice.
- Discounts after the fact: you agree to a price reduction or goodwill gesture after the invoice was sent.
- Overpayment: the client paid too much and you want to record a credit on their account.
Watch out: Do not delete or overwrite an issued invoice, and never reuse its number. Doing so breaks your audit trail and may cause problems with tax records. Correct it with a credit note instead.
What to Include on a Credit Note
A credit note looks much like an invoice, with a few differences in wording and purpose. Make sure it includes the items below.
| Field | What to write |
|---|---|
| Title | "Credit Note" in a prominent position |
| Credit note number | A unique number, either in a separate series or in your normal sequence |
| Date | The date you issue the credit note |
| Original invoice reference | The number and date of the invoice being corrected |
| Your details and the client's | The same names and addresses as the original |
| Reason for the credit | A short explanation, such as "Incorrect quantity billed" |
| Line items credited | Descriptions, quantities and prices being reduced |
| Tax adjustment | The tax amount being reversed, if any |
| Total credit | The total amount credited to the client |
Step-by-Step: Creating a Credit Note
- Find the original invoice. Check its number, date, lines, tax and total.
- Decide the amount. Is it a full credit that cancels the invoice or a partial one that fixes a single line?
- Create a new document titled "Credit Note" and give it a unique number.
- Reference the original invoice by number and date, and add a brief reason.
- List the credited items. Show the amounts as credits, either as negative values or clearly labelled as credits, according to your usual practice.
- Adjust the tax. If tax was charged on the original, reverse the matching amount. Check local rules on how this must be displayed.
- Send it to the client with a short, polite explanation, and keep a copy in your records.
Tip: You can build a credit note with our invoice generator by using the same layout, adding "Credit Note" in your invoice number or notes and entering the credited items. Check local requirements on exact wording for tax purposes.
A worked example
Suppose you sent invoice 2026-032 for 1,000.00, including a 100.00 line for a service that the client later cancelled. You can issue a partial credit note.
- Credit note number: CN-2026-004.
- Reference: "Credit against invoice 2026-032 dated 3 June 2026."
- Reason: "Cancelled add-on service."
- Credited amount: 100.00, plus any tax applied to that line.
The client now owes 900.00, plus tax on the remaining items, rather than the original 1,000.00. If the client had already paid in full, you would either refund the 100.00 or keep it as credit towards the next invoice.
Credit Note vs Replacement Invoice, and Tax Points
Sometimes the fix is bigger than a small adjustment. If an invoice is wrong in several ways, many businesses issue a credit note for the whole original and then send a fresh, correct invoice with a new number. This is clean and easy to follow, although it creates two documents instead of one.
Whichever route you choose, be consistent and keep a note linking the documents. For help with sensible numbering, read how to number your invoices. To understand what a corrected invoice should show, see what to include in an invoice.
A credit note is not an admission of failure. It is a sign of tidy bookkeeping, and clients appreciate a clear, documented correction.
Tax and record-keeping points
For businesses that charge VAT, GST or sales tax, a credit note usually has tax consequences, because the tax charged on the original invoice may need to be reduced. Rules differ by country, including how the credit note must be worded and when the adjustment is reported. If you are unsure, ask a local tax professional. You can also read our overviews of VAT and GST for general background.
Keep each credit note with the invoice it relates to, so that the pair can be found together if there is ever a query.
Frequently Asked Questions
Is a credit note the same as a refund?
No. A credit note is a document that reduces what the client owes or records a credit on their account. A refund is the actual return of money. You may issue a credit note and then refund the client, or let them use the credit against future invoices.
Can I issue a credit note for an unpaid invoice?
Yes. In that case, the credit note reduces the amount that is still due. The client then only pays the balance.
How long should I keep credit notes?
Keep them for as long as you must keep other financial records. The required period differs by country, so check with a local professional.
