Hi -actiontransport, thanks for getting back to us with this additional information

Indirect edits by system administration are normal and show changes made automatically by QuickBooks. These can happen for a number of reasons, including:

• You change a record, and the change affects another record. For example, if you edit a payment and link it to a different invoice, you may see a System Administration event for a change to the original invoice.
   
• You connect a third-party app to QuickBooks. When the third-party app sends data to QuickBooks, or when it makes a change to your existing data, this appears as a System Administration event.

• You create a recurring transaction, such as a recurring expense. When QuickBooks automatically adds an instance of the transaction to your books, a System Administration event appears in the audit log.

With regard to the automated payment, this can happen when the setting to automatically apply credits is turned on. This will apply any unapplied payment/credit note to the next invoice generated for the same customer. 

You can check and manage this setting by going to the Gear > Account & settings > Advanced > Automation. If you need further support, we recommend reaching our team by chat messaging or by clicking the Help icon to connect with an expert. The agents available here will have access to set up a remove screen share with you to enable them to view this with you.
