Hello there, Wong.
In QuickBooks Online (QBO), we're unable to delete the activities in the audit log to maintain the integrity of the data and provide a complete record of all actions taken within the system. It can also be helpful if you accidentally delete a transaction and need to recover its details.
I'll share this article to learn more about the audit log: Use the audit log in QuickBooks Online.
Furthermore, QBO offers many reports to help you obtain an overview of your business.
Please don't hesitate to reach out if you have any other questions about the audit log. We're always here to help. Stay safe!
