On the Bank Transaction page why is bank balance different from quickbooks balance?

I can explain why your bank balance is different from your QuickBooks balance, spcohen. 

There are different reasons why you have different balances in your bank and QuickBooks. The bank balance contains the actual transactions from your bank, while the QuickBooks balance is the balance in your Chart of Accounts (COA) as you create your transactions. 

Here are the other reasons why QuickBooks balance is different than the actual bank balance:

1. Missing transactions that are not recorded in QuickBooks Online (QBO).
2. Duplicate or incorrectly entered transactions.
3. The beginning balance in QBO is incorrect.
4. Previous reconciled bank transactions were edited or deleted.
5. There are outstanding transactions.
6. Some expenses have cleared the bank but haven't been entered into QuickBooks.

Thus, it's best to ensure that there are no missing transactions, duplicates, or incorrect transactions entered in your COA since this can cause discrepancies in your balances.
