All my bank entries match my quickbooks entries, then why when i try to reconcile it is off by over 3000.00?

Hi there, 

Just like balancing your chequebook, you need to review your accounts in QuickBooks to make sure they match your real-life bank and credit card statements. This process is called reconciling. It's great that you're taking advantage of the Reconcile tool in QuickBooks Online. If you're noticing issues when trying to reconcile, don't worry. I'm here to help you get to the bottom of this. 

I'd encourage you to review this helpful article about the reconciliation process in QuickBooks: Learn the reconcile workflow in QuickBooks. Use this guide anytime you need help starting or fixing a reconciliation.

If you're seeing issues during a reconciliation, and you've already reviewed your opening and beginning balances, you can focus on the ending balance in QuickBooks. At the end of your reconciliation, the difference between the ending balance in QuickBooks and your bank statement should be $0.00.

If there's still a difference, your accounts still aren't balanced.
