If Tip Reporting is enabled, the Pre-Authorization Advice List transaction and the Tip Totals report appear as menu items.
Pre-Authorization Advice List
From this Advice list, you can complete or delete multiple Pre-Auth transactions as well as record a Tip amount (if any was added by the cardholder) for every completion.
The Tip Totals report
This report prints a summary of all Tip amounts entered for Purchase and Pre-Authorization Advice transactions stored in the current or a previous batch.
