How is the "difference" calculated when I reconcile my account? The bank matches dollar for dollar but it is still telling me that there is a difference.

I can tell how the difference is calculated when you reconcile a bank account, aphelps@deafinte.

During the reconciliation process, you enter the ending balance. The amount should match with what you have on the real-life bank account. Same goes with the begoinning  balance. 

Once you select a transaction from the Payment or Deposit field, they're deducted from the beginning balance. Here's the screenshot of the formula.

After reconciling your account, you can review your work:

1. Go to the Accounting menu and select Reconcile.
2. Select History by account.
3. Use the drop-down menus to select the account and date range. Or print or export your reconciliation reports if you need to share them.
   
   

You can make changes to past reconciliations, but be careful. Changes can unbalance your accounts and other reconciliations. It also affects the beginning balance of your next reconciliation.

Start by reviewing a previous reconciliation report. If you reconciled a transaction by mistake, here's how to unreconcile it. If you adjusted a reconciliation by mistake or need to start over, reach out to your accountant.
