What do you need to do to finalize bank reconciliation in QuickBooks Online?

To finalize bank reconciliation in QuickBooks Online, it is essential to ensure that all transactions are matched with the bank statement. This process involves comparing the transactions recorded in QuickBooks with those listed on the bank statement to confirm that they align. When all transactions match, it indicates that your accounting records are accurate and complete, which is crucial for maintaining the integrity of financial reports. This matching process helps in identifying any errors or omissions in the accounts, which can then be corrected before the reconciliation is marked as complete.

In the context of the other options, exporting data for external analysis, updating customer records, or deleting discrepancies may seem relevant in different scenarios, but they do not specifically pertain to successfully finalizing a bank reconciliation. The primary goal is to achieve a one-to-one match of transactions, ensuring your accounts reflect true bank activity, which is vital for accurate financial reporting and management.
