How to Create a Credit Memo in Xero

Creating a credit memo in Xero is a straightforward way to correct an invoice, refund a customer, or write off a small amount. A credit memo reduces what a customer owes you, and you can apply it to a future invoice or issue a refund. Before you start, make sure you have the customer’s details and the original invoice number handy. You’ll also need to know whether the credit is for the full amount or a partial amount, and whether tax was included on the original invoice.

What You’ll Need

• An active Xero account with billing or adviser access.
• The customer’s name or email address as it appears in Xero.
• The original invoice number (if you’re crediting a specific invoice).
• The amount to credit, including the tax rate that applies.
• A reason for the credit (for your own records and the customer’s).

Step-by-Step

1. Log in to Xero and go to the Business menu, then select Sales.
2. Click the New button (top right) and choose Credit Note from the dropdown. (If you don’t see it, click More and look under Invoices.)
3. In the To field, select the customer. If they aren’t listed, type their name and click Add to create a new contact.
4. Choose a Date for the credit memo. This is usually the date you’re issuing the credit, not the original invoice date.
5. Enter a Reference (optional but helpful) – for example, “Credit for invoice INV-001” or a reason code.
6. Add the line items. You can either:
   • Click Add an item and select the product/service, then enter the quantity and rate, or
   • Click Add a line to type a description and amount manually.
7. Make sure the tax rate on each line matches the original invoice. If the original invoice was tax-inclusive, the credit should be too.
8. Check the total at the bottom. It should be the amount you want to credit (including tax if applicable).
9. If you want to apply this credit to a specific invoice, click Add to invoice and select the invoice. Otherwise, you can leave it unallocated and apply it later.
10. Click Save (top right). Xero will create the credit memo with a status of Draft.
11. To finalize, click Approve. The credit memo is now active and will affect the customer’s balance.
12. If you need to email it to the customer, click Send and choose your email template, or download a PDF copy.

Common Mistakes

• Wrong tax rate – If the credit memo uses a different tax rate than the original invoice, the numbers won’t match and can cause reconciliation headaches.
• Crediting the wrong customer – Double-check the customer name before saving, especially if you have similar names.
• Forgetting to allocate – If you don’t apply the credit to an invoice, it sits as a “credit available” and might be overlooked.
• Duplicating credits – Issuing a credit memo and then also voiding the original invoice can double-reduce revenue.
• Using a credit memo for a write-off – For small write-offs, consider using the “Write off” function instead to keep things clean.

Tips

• Use a consistent reference format like “CR-2025-001” to make credits easy to search.
• If you’re crediting a partial amount, only include the lines or quantities that are being credited.
• Set up a default credit note template with your logo and terms to save time.
• After approving, you can still edit the credit memo as long as it hasn’t been applied to an invoice or refunded.
• If you need to reverse a credit, you can create a new invoice for the same amount instead of deleting it.

Troubleshooting

I can’t find the “Credit Note” option. Make sure you’re in the Sales area (not Purchases). If you still don’t see it, click the “New” button and scroll down – it might be under “More”.

The tax amount is wrong. Check the tax rate on each line. If the original invoice had a special rate (like GST-free), you’ll need to select that same rate. If the total tax is still off, verify that the “Amounts are tax inclusive” setting is correct (top right of the credit note).

The credit memo won’t approve. Usually this happens because a required field is missing (like a line item or a contact). Look for red error messages at the top of the page.

I applied the credit to the wrong invoice. You can remove the allocation by editing the credit memo and clicking “Remove” next to the invoice link, then re-apply to the correct one.

The customer’s balance doesn’t change. Check that the credit memo is approved and not still in draft. Also confirm that it isn’t sitting as unallocated – if it’s unallocated, it reduces the overall balance but not a specific invoice.

Frequently Asked Questions

Can I create a credit memo without a prior invoice? Yes, you can create a standalone credit memo for a customer, but it’s usually better to link it to an invoice to keep records clear.

Can I apply a credit memo to a future invoice? Absolutely. When you create a new invoice for that customer, you’ll see an option to apply available credits.

What’s the difference between a credit memo and a refund? A credit memo reduces what the customer owes; a refund is actual money returned. You can create a credit memo and then issue a refund against it.

Can I delete a credit memo? You can delete a draft credit memo, but once it’s approved, you can’t delete it. You can void it, which keeps a record but marks it as invalid.

Does a credit memo affect my sales tax report? Yes, it will reduce your taxable sales and tax collected for the period, so make sure the tax rate is accurate.

Can I email a credit memo to the customer? Yes, after approval, click “Send” and choose your email template. The customer will receive a PDF with the credit details.
