Does a Credit Memo Refund the Customer in NetSuite?

The screenshots show sample data. Person and operating-company names are fictional. Use your own records and values when following the steps.

Before you start

Check whether the customer has paid the invoice, because that decides what the credit memo does. On an unpaid invoice, the credit reduces the balance and the customer owes less. A fully paid invoice has no open balance for the credit to land on, so the credit stays unapplied unless you apply it to another open invoice. To apply it to the original invoice, the payment generally has to be unapplied first. That unapplied credit is what a customer can use later, or what you refund.

You need Accounts Receivable enabled and a role that can view invoices and create credit memos, plus access to the customer's subsidiary, location, and currency. The posting period has to be open. Your account may also route credit memos for approval, and a custom form, workflow, or tax setup can add required fields, change defaults, or hide the Credit button. If you don't see Credit on an invoice, check your role's permissions and the invoice's status first. If goods are coming back, a return authorization and receipt may fit better than a credit started straight from the invoice, because the inventory and accounting effects differ.

This example starts by creating the invoice being credited: customer 1 Test company, location Test Location, memo test invoice, and one Test Widget line for 100.00, entered from Transactions > Sales > Create Invoices. If you already have the invoice, open it and start at step 1.

01. Check what the invoice still owes

Open the saved invoice and look at its status and Summary. Here, INV13 for 1 Test company is Open, with a Total of 100.00 and an Amount Due of 100.00. The full amount is still owed.

If Amount Due is lower than Total, the invoice already has a payment, credit, discount, write-off, or other application against it. Check the transaction history before deciding how much to credit. The invoice can only absorb a credit up to the remaining amount. Anything above it stays unapplied, or you apply it to another invoice.

02. Click Credit on the invoice

Click Credit in the invoice's button row. Which buttons appear, and in what order, depends on your role, form, and enabled features. In this account Credit sits between Accept Payment and Renew, and it's easy to grab the wrong one. Accept Payment opens a customer payment for the invoice, and Authorize Return starts a return authorization for goods coming back. Credit opens a new Credit Memo filled in from the invoice.

03. Check Applied and Unapplied before saving

The credit memo opens on the STR E - Credit Memo form, and Credit # reads To Be Generated until you save. Check what came across from the invoice: Customer 1 Test company, Location Test Location, Memo test invoice, Date 7/10/2026, and Posting Period Jul 2026. The Summary shows a Total of 100.00. Review the Items subtab too, since the credited lines, quantities, and amounts come from the invoice.

Then look at Apply. In this example, NetSuite has already filled in Applied 100.00 and Unapplied 0.00, so the whole credit is set to be applied rather than left open. Don't count on that in every account, and don't assume the full credit is selected. If Applied is 0.00, select the invoice in the apply list yourself. For a partial credit, change the line quantity, rate, or amount where your form allows it, then recheck tax, the Total, and both numbers. Click Save.

04. Confirm the credit memo is fully applied

NetSuite shows Transaction successfully Saved and opens CM12 for 1 Test company with the status Fully Applied. Apply shows Applied 100.00 and Unapplied 0.00, against a Total of 100.00.

For this invoice, that answers the refund question. The whole 100.00 credit was applied, nothing is left unapplied, and saving the credit memo didn't create a customer refund or any payment to the customer.

Fully Applied tells you the credit is used up, not where it went. Open the credit memo's apply list to confirm INV13 is the invoice it was applied to, then reopen INV13 to check its status and amount due. To confirm no refund exists, look at the credit memo's Related Records subtab or the customer's transactions. The recording stops at the saved credit memo, so none of those screens is shown. If your account requires approval, the credit memo may show a pending status before it applies, and you shouldn't call it fully applied until it does.

Check the result

1. CM12 is saved for 1 Test company with a Total of 100.00.
2. The status is Fully Applied, with Applied 100.00 and Unapplied 0.00.
3. The credit memo's apply list shows INV13 as the invoice that received the credit.
4. No customer refund appears in the related records or the customer's transactions. If the customer should get money back, that's a separate transaction.

Common questions

When do I need a customer refund instead of a credit memo?

When the customer is owed money and a credit is sitting unapplied. A credit memo only gives the customer credit on their account, which can reduce an open invoice or a future one. Paying that credit back by check, card, or another method is a separate customer refund, and what's available depends on your account setup and permissions. The credit memo in this guide never needed one, because the whole 100.00 went against the open invoice.

What happens if I credit an invoice that's already been paid?

The example doesn't show this case, so don't assume it behaves like INV13. With no open balance on the invoice, the credit usually stays on the customer's account as unapplied credit. You can then apply it to another open invoice or refund it. To apply it to the original invoice, the payment generally has to be unapplied first. Check the saved credit memo's status and unapplied amount to see where it landed.

What's the difference between Fully Applied and Open on a credit memo?

Fully Applied means the whole credit has been used, so none of it is left. Open means some or all of it is still unapplied. CM12 is Fully Applied because Applied is 100.00 and Unapplied is 0.00. If your account routes credit memos for approval, you may see a pending status first.

Does a credit memo move cash or only change the books?

It changes the books and doesn't move cash. Saving CM12 created no refund transaction. A credit memo usually reduces Accounts Receivable and reverses the accounts behind the credited lines, such as revenue and tax, and inventory when goods come back. The recording doesn't show the GL impact, so check it on the saved record in your own account.

How can I tell which invoice a credit memo was applied to?

Open the saved credit memo and look at its apply list, which shows the invoices that received the credit and the amount applied. Fully Applied alone won't tell you which invoice that was. The Related Records subtab is another place to look. A credit memo entered on its own can be applied to an invoice without being created from it, so the apply list is the more reliable check.
