Glad to have you here in the Community, @brookermans.
I'm here to ensure you can apply the unapplied payments to your old invoices.
One of the possible reasons why there are unapplied payments is that the invoices were deleted. Let's run the Audit trail report to verify. Here's how:
- Go to the Reports menu, then select Accountant & Taxes.
- Choose Audit Trail.
- On the report screen, click Customize Report.
- Go to the Filter tab, then search for the Transaction type.
- Choose Invoice and click OK.
- Find the missing invoices.
If the missing invoices were deleted, you have to recreate them and link the unapplied payments. To link them, you can follow the detailed steps provided by my colleague GlinetteC above.
If the invoices weren't deleted, you want to run the Customers & Receivables report. This way, we can verify if the payments were just unapplied.
- Go to the Reports menu, then select Customers & Receivables.
- Choose Open Invoices.
- Verify the invoices and payments from the report.
- If you see Open balance to your invoices, open them manually, then apply the unapplied payments.
Just in case you encounter a difference in the A/R balance in the Chart of Accounts and A/R balance on reports, feel free to check out this article for more details: AR balance on the Chart of Accounts does not match AR balance on reports.
Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day.
