Quickbooks is creating and emailing invoices without my permission of me settings it up.

Hi there, @aecintercom.

This may be caused by the recurring transaction of an invoice. Or someone that has access to your QuickBooks company made the transactions.

You'll need to check if there's an invoice recurring transaction. Locate the invoice that was sent, if you can see that, you'll have to Pause it before deleting it. This is how it looks like:

However, if there's no active recurring invoice that's having the same details as the sent ones. You should check the Audit log in the Settings. To know more about how to use this feature, you may check out this article: Use the audit log in QuickBooks Online.

I've added this relevant resource that may help you with your future task about managing your customer's payments: Process a credit card payment in QuickBooks Online.

I'll be here if you have questions about QuickBooks. Just let me know in the comment section. Take care always.
