A credit memo and a credit note are the same document. Both are issued by a seller to reduce or cancel the amount a customer owes on an earlier invoice, for example after a return, an overcharge, a discount or a cancelled order. "Credit memo" is the usual term in the United States. "Credit note" is the standard term in the UK, the EU, Australia and most other countries.
The document does the same job under either name: it references the original invoice, states the amount credited (plus any tax), and carries its own number. The label is regional habit, not a legal or accounting difference.
Credit memo vs. credit note vs. debit note vs. refund
The real confusion is usually not between the two names, but between a credit memo and its neighbors. This table separates them.
| Credit memo | Credit note | Debit note (debit memo) | Refund | |
|---|---|---|---|---|
| What it is | A document that lowers the customer's balance | Same document as a credit memo | A document that raises the customer's balance | Money actually paid back |
| Who issues it | Seller | Seller | Seller (or a buyer, in some industries, to claim a deduction) | Seller |
| Effect on amount owed | Decreases | Decreases | Increases | No change to the invoice; cash leaves your account |
| Typical reasons | Return, overcharge, discount, cancellation | Return, overcharge, discount, cancellation | Undercharge, extra items, added freight | Customer paid and is owed money back |
| Where the term is common | US, US accounting software | UK, EU, Australia, India, international trade | Worldwide | Worldwide |
| Moves money? | No | No | No | Yes |
The key rule: a credit memo or credit note adjusts the balance, a refund moves cash. A credit note can lead to a refund, but it is not one. A debit note works in the opposite direction to both.
Why two names exist: US vs. UK/EU terminology
"Credit memo" is short for "credit memorandum", a term that grew out of American bookkeeping. US accounting systems such as QuickBooks and NetSuite use it, and so do most US companies on their documents.
"Credit note" is the British and European term. EU VAT rules treat a document that amends an invoice as part of the invoicing system, and national tax authorities usually call it a credit note in English. HMRC in the UK uses "credit note" in its VAT guidance. Australia, New Zealand, India and Singapore follow the same usage.
You may also see:
- Credit invoice or negative invoice, in some European countries.
- Credit memo request, in ERP systems such as SAP. This is an internal approval step before the actual credit memo is created.
- Bank credit memo, a different thing entirely. It is a notice from a bank that it has added money to your account, for example interest or a corrected fee.
Some larger systems also use "credit memo" for the internal accounting entry and "credit note" for the customer-facing PDF. That is a software detail. For a small business sending a correction to a client, the two names are interchangeable.
Which should you use? Use the term your clients expect. Selling mainly to US customers: "credit memo". Selling in the UK, the EU or internationally: "credit note". If your tax authority prescribes a specific title, use that title.
Worked example with VAT
A UK supplier sells 10 units at £100 each to a business customer. VAT is 20%.
Original invoice INV-1042
| Item | Amount |
|---|---|
| 10 units × £100 | £1,000.00 |
| VAT at 20% | £200.00 |
| Invoice total | £1,200.00 |
Three units arrive damaged. The customer returns them and the supplier agrees to credit them.
Credit note CN-0019 (referencing INV-1042)
| Item | Amount |
|---|---|
| 3 units × £100 returned (damaged) | −£300.00 |
| VAT at 20% | −£60.00 |
| Total credit | −£360.00 |
Result
- New amount owed: £1,200.00 − £360.00 = £840.00 (£700 net + £140 VAT).
- If the customer has not paid yet, they pay £840.
- If the customer already paid £1,200, they now have a £360 credit balance. You can refund it or apply it to their next invoice.
- Your VAT return shows output VAT reduced by £60 for the period in which you issue the credit note. Your customer reduces the input VAT they reclaim by the same £60.
The same arithmetic applies in the US with sales tax instead of VAT: credit the net amount and the sales tax charged on it. In the US the document would normally say "Credit Memo" at the top. The figures and the logic do not change.
Tax treatment differs by country, for example the period in which the adjustment is reported. Check the details with your accountant.
What a credit memo or credit note must include
Whichever name you use, include:
- The title: "Credit Note" or "Credit Memo".
- Its own unique number, for example CN-0019.
- The issue date.
- Your business name, address and tax or VAT number.
- The customer's name and address.
- The number and date of the original invoice.
- The reason for the credit: return, error, discount or cancellation.
- The items or amount credited, net of tax.
- The tax rate and tax amount credited.
- The total credit.
Missing the original invoice reference is the most common problem. Without it, neither you nor the customer can match the credit to the right balance.
How to issue a credit memo or credit note, step by step
- Find the original invoice. Note its number, date, line items and tax rate.
- Agree the reason and amount with the customer. Confirm which items or how much you are crediting.
- Calculate the credit. Credit the net amount and the tax at the same rate as the original line.
- Number the document. Use a separate sequence such as CN-0001, or a clearly marked entry in your main sequence. See invoice numbering.
- Create the document. Our free credit note generator lets you enter the original invoice number, reason and items, and download a PDF. You can title it "Credit Memo" if your customers are in the US.
- Send it to the customer and keep a copy with the original invoice.
- Record how the credit is used: a refund, an offset against the open balance, or a credit held for the next invoice.
- Update your records. Your accounts receivable and the customer's statement of account should show the adjustment.
Never edit or delete the original invoice. The credit memo exists so that the original stays intact and the correction is visible. For more on when a credit is the right fix, see our guide to credit notes.
Common mistakes
- Deleting or reissuing the invoice instead of crediting it. This breaks your audit trail and, in VAT countries, your invoice sequence.
- Forgetting the tax. If the original invoice charged VAT or sales tax, the credit usually must too.
- Calling a refund a credit memo. Issue the credit memo first, then record the refund against it.
- Using a debit note when you mean a credit note. A debit note increases the balance.
- Treating the name as important. Spend your time on the content, not on choosing between "memo" and "note".
FAQ
Is a credit memo the same as a credit note?
Yes. Both are documents issued by a seller to reduce the amount a customer owes on an earlier invoice. "Credit memo" is the common US term. "Credit note" is the common term in the UK, the EU and most other countries.
Is a credit memo the same as a refund?
No. A credit memo reduces the customer's balance. A refund returns money to the customer. You often issue a credit memo first and then pay a refund against it, but many customers prefer to keep the credit for their next order.
What is the difference between a credit note and a debit note?
They work in opposite directions. A credit note lowers what the customer owes, for example after a return. A debit note raises what the customer owes, for example after an undercharge.
Do I need to number credit notes separately?
Each credit note needs a unique number. Many businesses use a separate series such as CN-0001. Some countries require a continuous sequence, so ask your accountant what your local rules say.
Can I issue a credit memo after the customer has paid?
Yes. The customer then has a credit balance. You can refund it or apply it to a future invoice. Note on the credit memo which option you chose.
Does a credit note have to cancel the whole invoice?
No. A credit note can be partial. It can reduce one line, part of a quantity, or apply a percentage discount. To cancel an invoice completely, credit the full amount and reference the original invoice.
