Reconciliation not working

Hello there, @TUSSU. Let me help you identify where the issue is coming from so you can reconcile your account.

Several factors may cause the balances to vary when reconciling your account in QuickBooks. Since you verified that the opening and closing balances are correct and all entries are in your bank statement, I'd recommend checking the transactions entered in QuickBooks.

That way, we can check were the balance came. Here’s a list of possible reasons why these balances don’t match:

• Outstanding transactions
• New transactions for a connected account
• Duplicate transactions
• Edited or deleted transactions
• Unreconciled in the register or reconciled in error.

Depending on the factor that’s mentioned, there are different steps to fix your issue. Here’s an article on the steps to fix or adjust these factors: How to Fix Differences Between QuickBooks Balance and Bank Balance.
