In QuickBooks Online you can view your monthly subscription invoice in the Billing and Subscription section from the Account and Settings. I'll show you how.
Go to the COG wheel icon.
Select Account and Settings.
From the Billing and Subscription tab, click View Payment History.
Also, keep in mind that you can only view invoices for the last six months. If you want to view older invoices, please contact our support team. Here's how:
