Mistakes happen in accounting. A credit memo gets applied to the wrong invoice. QuickBooks automatically applies a credit to a new customer transaction when you did not intend it. A vendor credit gets linked to the wrong bill.
When any of these situations occur, you need to unapply the credit and correct the record — before it affects your financial statements, your reconciliation, or your client's balance.
This guide explains exactly what a credit memo in QuickBooks Desktop is, when and why you need to unapply one, and the step-by-step process to remove a credit memo from both a customer invoice and a vendor bill. We also cover how to find credit memos in QuickBooks Desktop and the common mistakes to avoid throughout the process.
A credit memo in QuickBooks Desktop is a document that records a reduction in the amount a customer owes your business. You create a credit memo when a customer returns a product, when you need to correct an overcharge, or when you want to issue a credit for services not delivered.
When you create a credit memo, it appears in the customer's account in accounts receivable. QuickBooks then gives you three options for how to handle it:
Once a credit memo is applied to an invoice, it reduces the invoice balance by the credit amount. QuickBooks links the two transactions together. If you need to undo that link — because it was applied incorrectly, applied to the wrong invoice, or applied automatically when you did not intend it — you need to unapply the credit memo.
This is distinct from deleting or voiding the credit memo. Unapplying simply removes the link between the credit and the invoice without deleting either transaction. The credit memo returns to an available credit status in the customer's account. As explored in how to write off bad debt in QuickBooks Desktop, credit memos play a central role in accounts receivable management — and applying or unapplying them correctly directly affects the accuracy of your customer balances.
There are several common situations where unapplying a credit memo in QuickBooks Desktop becomes necessary.
Applied to the wrong invoice. You created a credit memo and applied it to an open invoice, but it should have gone to a different invoice. You need to unapply it from the first invoice and reapply it to the correct one.
Automatically applied by QuickBooks. QuickBooks Desktop sometimes applies available credits to open invoices automatically when you receive a payment. If this auto-application was not your intention, you need to unapply it and decide manually where the credit should go.
Customer requests a refund instead. You applied the credit to an invoice, but the customer now wants the money back instead. You need to unapply the credit from the invoice and then issue a refund.
Credit applied to the wrong customer. A credit memo was linked to the wrong customer account. You need to unapply it, correct the customer association, and reapply it properly.
Vendor credit applied to the wrong bill. On the accounts payable side, a vendor credit was applied to the wrong bill. You need to remove the credit from that bill and apply it to the correct one.
Before you can unapply a credit memo, you need to locate it. Here is how to find all credit memos in QuickBooks Desktop:
QuickBooks now displays all credit memos in your system. You can see which customer each credit memo belongs to, the amount, the date it was created, and whether it has been applied. Find the credit memo you need to unapply and note the customer and invoice it is linked to.

This is the most common scenario — removing a credit memo that has been incorrectly applied to a customer invoice. These steps come directly from Intuit's official QuickBooks Desktop support documentation.
The credit memo is now unapplied. The invoice returns to its original unpaid balance. The credit memo returns to an available credit status in the customer's account — ready to be applied correctly to the right invoice.
Important note: Do not delete the credit memo after unapplying it unless you intend to remove it from the system entirely. Unapplying simply unlinks it. The credit remains available for future use.
If you need to unapply a vendor credit from a bill on the accounts payable side, the process is different. QuickBooks Desktop does not use the same Apply Credits window for vendor transactions. Instead, you temporarily change the transaction type to remove the link.
Step 1 — Find the vendor credit:
Step 2 — Change the transaction type to Bill:
Step 3 — Change it back to Credit:
This process removes the link between the vendor credit and the bill. The vendor credit now shows as an available credit in the vendor's account. The bill returns to its original unpaid status.
You can now apply the vendor credit to the correct bill by going to Vendors → Pay Bills, selecting the correct bill, and checking the credit in the Credits section of the payment window.

When you unapply a credit memo from a customer invoice:
When you unapply a vendor credit from a bill:
Always run your Customer Balance Detail report and Vendor Balance Detail report after making these changes to confirm that balances reflect the correction accurately. Reconciling after any credit adjustment is good practice — as covered in how to reconcile in QuickBooks Desktop, regular reconciliation is the fastest way to catch any remaining discrepancies after corrective transactions.
Deleting the credit memo instead of unapplying it. Deleting removes the credit memo from the system entirely. If the customer is owed that credit, deleting it causes a discrepancy in their account. Use unapply — not delete — unless you are certain the credit memo should not exist at all.
Forgetting to reapply the credit correctly. After unapplying, the credit memo sits as available credit. If you do not reapply it to the correct invoice or issue a refund, the customer's balance will be overstated until you do. Complete the correction immediately.
Not checking the transaction history first. Always use Ctrl + H to view the Transaction History before making changes. This confirms exactly which transactions are linked and prevents accidental changes to the wrong record.
Unapplying in a closed period. If the credit memo was applied in a period that has already been closed for reporting, unapplying it will affect that period's balances. Check with your manager or review your firm's period-close policy before making changes to closed-period transactions.
Correcting transactions like credit memos in QuickBooks Desktop is straightforward when you are the only one in the file. But when multiple team members or clients need access to the same QuickBooks company file — including for making corrective adjustments — coordination becomes essential.
Qbox is accounting collaboration software built specifically for accountants, bookkeepers, and CPA firms using QuickBooks Desktop. It makes multi-user access to QuickBooks files secure, organized, and conflict-free.
When one team member opens a QuickBooks Desktop file to unapply a credit memo or make any other correction, Qbox automatically locks the file so nobody else can write to it at the same time. The moment they save and close the file, Qbox syncs the updated version to every authorized user instantly. No two people accidentally edit the same record at the same time. No overwritten corrections. No version confusion. See more about how Qbox supports QuickBooks Desktop file sharing and collaboration.

Files land in the right folder automatically. Your team gets notified instantly. No sensitive documents traveling through unencrypted email.
Create a task for every credit memo correction — with the specific invoice, the credit amount, the reason for the change, and the team member responsible. Track completion from one dashboard. When a correction needs a second set of eyes before it is finalized, assign a review task to a manager. Nothing gets missed. Every corrective action is documented and trackable.
When a question arises about a credit memo — whether it should be unapplied, refunded, or reapplied to a different invoice — discuss it inside Qbox, tied to the right client record. The conversation stays connected to the work. No hunting through email threads for context weeks later. For a deeper look at how Qbox supports accounting workflows end to end, see how to share custom reports in QuickBooks — and how keeping files, tasks, and communication in one place makes every QuickBooks Desktop workflow cleaner.
Unapplying a credit memo in QuickBooks Desktop is a straightforward corrective process once you know the right steps.
