Hi there, @TSPI.

I understand how challenging it is to encounter random audits in your QuickBooks Online. Rest assured, I'm here to assist you in handling this. You'll need to turn off the Automatically Apply Credits feature so that any credits available will not automatically apply to your customers' open invoices and avoid the system triggering the System Administration event.

Here's how:

1. Head to the Gear icon and select Accounts and Settings.
2. Go to the Advanced tab.
3. Look for the Automation section and disable the Automatically Apply Credits option.
4. Click Save.

There are also several factors why you're seeing other transactions added by System Administration in your audit log:

• Recurring transactions are automatically created by system administration every time it runs.
• System Administration event will also appear when there's an update to your bank feeds, even when you're not signed in.
• Connecting to a third-party app can also trigger the system administration even to appear in your audit log.
• Editing a payment and linking it to a different invoice will trigger system administration even for a change to the original invoice.

Additionally, you can also consider running a report to review your transactions made and identify which are legitimate.

You're always welcome to post here in the community if you have additional concerns related to audit logs. I'd be glad to assist you at any time.
