Final answer:
The statement that you should never click the Reconcile Now button unless the difference is zero is true. Reconciliation is important to ensure that your books match your bank statements, and discrepancies should be resolved before finalizing.
Step-by-step explanation:
You asked whether it is true or false that you should never click the Reconcile Now button in the Reconcile window unless the difference is zero. This statement is true. It is important in accounting to ensure that your books match the bank statements, which is the process of reconciliation. If the difference is not zero, it means there are discrepancies that need to be resolved before finalizing the reconciliation. Clicking the Reconcile Now button with a difference other than zero would mean your accounts may not actually balance, which can lead to financial errors.
