How to Fix Unapplied Payments in QuickBooks (Step-by-Step)
Unapplied payments are a common issue in QuickBooks — and one of the easiest to fix once you know where to look. They happen when a payment is recorded but not linked to an invoice. The result: invoices show as unpaid, payments sit separately, and reports don't reflect reality. This guide walks you through exactly how to find and fix unapplied payments step-by-step.
What you're fixing
Before jumping into the steps, it helps to understand the problem.
An unapplied payment means a payment exists in QuickBooks, but it hasn't been matched to an invoice. Until it's applied, the invoice remains open and the payment doesn't reduce the balance.

Upload your QuickBooks file and find every unapplied payment instantly — or follow the manual steps below.
Step 1: Find unapplied payments
Start by identifying where the issue exists. There are two ways to do this in QuickBooks Online.
Option A: Run a report
- 1
Go to Reports.
- 2
Search for "Unapplied Cash Payment Income".
- 3
Review the list of unapplied payments.
Option B: Check customer accounts
- 1
Go to Sales → Customers.
- 2
Select a customer.
- 3
Look for payments not linked to invoices.
This works, but can take time if you have a lot of data.
Step 2: Open the payment
- 1
Click into the payment record.
- 2
Review the amount and customer.
- 3
Confirm it should be linked to an invoice.
Step 3: Apply the payment
- 1
Locate the list of open invoices.
- 2
Select the appropriate invoice.
- 3
Apply the payment.
- 4
Save.
After applying, the invoice should show as paid and the payment will no longer be unapplied.
Step 4: Verify the fix
After applying payments:
- check the customer balance
- confirm invoices are closed
- rerun reports if needed
Everything should now reflect correctly.
Common mistakes to avoid
When fixing unapplied payments:
- Don't apply a payment to the wrong invoice
- Don't leave partial payments unmatched
- Don't ignore small leftover balances
Even small mismatches can cause issues later.
When this becomes time-consuming
This process works well for a few payments. But if your file has:
- dozens of customers
- many months of transactions
- multiple unapplied payments
…it quickly becomes tedious to track everything down manually.
