I appreciate the detailed information, Deycomin. Let me ease your confusion. 

The Bank balance and In QuickBooks balance will not be the same when transactions are imported manually. The Bank balance will only be changed or updated if the account is connected to online banking. The In QuickBooks balance will also depend on the added or matched transactions.

That being said, it's normal when you use WebConnect or CSV files.
