I have a payment that was posted to the wrong customer account.

Thanks for sharing your concern today, @cthornbrue. I'll guide you on how you can fix misapplied payments in QuickBooks Desktop (QBDT).

To isolate this issue, let's first create a duplicate payment to your correct customer:

1. Go to the Customers menu, then choose Receive Payments.
2. Create a duplicate payment for the correct customer.
3. Once done, hit Save & Close.

Then, let's delete the original payment that was incorrectly applied and then recreate the payment line in the deposit window. Here's how:

1. Go to the Banking menu and choose Make Deposits.
2. Select the Cancel button at the bottom.
3. Click the Previous button until you find the deposit with the incorrectly applied payment.
4. Click the Payments button at the top to open the Payments to Deposit page.
5. Select the newly created payment, then click OK to add it to the deposit.
6. In the Make Deposits window, select the original payment.
7. From the Edit menu, click Delete Line.
8. Select Save & Close to automatically replace the original payment.

Lastly, you'll have to delete the original payment:

1. Choose Receive Payments from the Customers menu.
2. Click the Previous button until you find the original payment.
3. From the Edit menu, choose Delete Payment.
4. Select OK to the warning, then Save & Close.

How can I correct a payment that was posted to the wrong customer account. Can journal entries be done?

Hello there, lushai. I'm here to ensure the payment will be posted and linked to the correct customer account.

Yes, you can create journal entries. However, I recommend consulting your accountant for proper categorization and to ensure the accuracy of books. If you don't have one, you can find a professional through this link: https://quickbooks.intuit.com/find-an-accountant/.

Moreover, you can follow BigRedConsulting's suggestion on correcting the payment posted to the wrong customer account.  

On the other hand, you can pull up the previous reconciliation report. It will help you ensure no issue or discrepancy after changing the transaction. 

You can return here anytime whenever you need information and assistance regarding customer payments. I'll always be here to support you. 

There is no "edit deposit" option. Please clarify.

I have similar situation, but original payment received was applied partially to the correct customer, so I can't create a new payment for that invoice because it shows as paid in full. How do I fix this, please?

RE: Can journal entries be done?

I can't think of a way Journals will help.  But the steps I wrote before should work.

RE: There is no "edit deposit" option.

Edit deposit option?  Not sure what you're looking for. To edit most any transaction in QuickBooks, open it and change it, and then save the change.

RE: I have similar situation, but original payment received was applied partially to the correct customer, so I can't create a new payment for that invoice because it shows as paid in full. 

Not sure what you're describing. Payments cannot be partially applied to the correct customer when they are posted to the wrong customer account.  Payments can only be applied to the payment's customer's invoices.
