RE: At this moment, the only way to flush audit trail records is to condense your data in QuickBooks Accountant Desktop.

Yes, you have to use Condense, but when you do nothing will be deleted except the Audit Trail. Which is what the customer is asking for. Why don't you know this?

RE: We recognize feedback and product suggestions to make the program better. You can submit your own feature requests through the Send Feedback Online option within your QuickBooks company file. 

You've sent the customer to request something QuickBooks clearly already has. While Intuit reps do that all the time here, aren't you sort of embarrassed? Just a little?
