Hi jwpemberton,

Thanks for joining in the thread. I'll guide you to move the deposits on your client's records, so you can reconcile their account.

Instead of creating a clearing account, you can open each deposit and replace the bank account with the new one, where those payments were posted in reality. Or, create a transfer for each to move the funds to the new account. Then, delete your transactions in the clearing account afterward.
 

Change the bank account:

1. Open one deposit transaction.
2. Change account in the Account field.
3. Click Save and close.

Create transfers:

1. Click on +New. and choose Transfer.
2. Select the old account in the Transfer Funds from field.
3. Choose the new account in the Transfer Funds to field.
4. Enter the amount and the date based on the payment transaction.
5. Click Save and close and do the same steps for the remaining deposits.

Speaking of reconciliation, I've got an article with steps and a video clip to guide you through the process. Please check this out: Reconcile an account in QuickBooks Online.

Let me know if you need more help as you move the deposits or as you reconcile your client's account. Have a great day!
