Balance sheet cash amount does not equal the general ledger balance QB Online

Hi there, @lo5335.

I can give you some tips on how to check for the difference and help you fix it. Please take note that this can affect your books. That said, seeking an accountant is recommended before proceeding.

You'll want to review the previous reconciliation report to check if there were transactions that were not supposed to be reconciled. I'll show you how:

1. Go to Accounting, then select the Reconcile tab. 
2. Click the History by account link.
3. Choose the Account and Report period.
4. Open the year with the statement ending date.
5. Click View report. 

This report will show all the reconciled transactions. You'll want to review the list and check what is causing the difference.

You can correct the unreconciled period by undoing the process. Check out this article that details that process: Undo or remove transactions from reconciliations in QuickBooks Online.

Also, you have to check your uncleard and cleared transactions and see if they're causing the difference. I'll guide you on how:

1. Open a Balance Sheet report.
2. Select your bank account by double-clicking on the amount.
3. In the Transaction Report overview, click the Customize button.
4. Expand the Filter view.
5. Check the Cleared box.
6. Select Cleared or Uncleared in the drop-down menu. 
7. Click Run report.

After finding what's causing the difference, you'll want to double check your General Ledger report and compare it with your register balance.
