Why are my connected bank account balances showing incorrect amounts?

Hi there. We appreciate the additional information you shared. Let's make sure your account balances are in order.

There are several possible reasons why your QuickBooks Online bank register balance doesn't match your bank balance. Here are the following:

1. Outstanding transactions.
2. New transactions for a connected account
3. Duplicate transactions.
4. Edited or deleted transactions.
5. Credit card (liability) account.

One way to ensure both balances match is through reconciliation. I agree with my colleague Ethel_A. You can prepare a copy of your bank statement and compare it with your transactions in QBO. Make sure to review your opening balance first. Then, you can start the reconciliation. Here's how:

Note: I suggest contacting your accountant for extra advice to keep things in order.

1. Open the Accounting menu.
2. Go to the Reconcile tab.
3. Select your account from the What account do you want to reconcile? drop-down.
4. Check the Beginning balance. Make sure the beginning balance in QuickBooks matches the one on your statement. Here's what to do if they don't match.
5. Fill in the Ending balance and Ending date on your statement. Some banks call the ending balance a "new balance" or a "closing balance."
6. If you see it, check the Last statement ending date. This is the end date of your last reconciliation. Your current bank statement should start the day after.
7. Once ready, click on Start reconciling.

After that, you can start comparing your statement with QuickBooks. See the image below for reference:
