Final answer:
When you click the Reconcile Now button in the Reconciliation window, the difference should be $0.00, which shows that the account transactions match your bank statement and your books are balanced.
Step-by-step explanation:
The difference in the Reconciliation window should be $0.00 when you click the Reconcile Now button. The goal of account reconciliation is to ensure that transactions in your accounting records match your monthly bank statements. A $0.00 difference indicates that all transactions have been accounted for correctly and that your books are balanced with the bank records. If the difference is not $0.00, it suggests there are outstanding transactions unaccounted for or discrepancies that need to be reviewed and corrected before finalizing the reconciliation process.
