Full total amounts for customers & sub customers

Hi there, Justine.

Yes, there is a report that can run the total invoiced amount for your customers and sub-customers in QuickBooks Online, and I'm here to assist you.

You'll need to run a Transaction List by Customer and customize it.

Here's how:

1. On the left menu, head over Reports.
2. Search for Transaction List by Customer.
3. Choose a Report Period. It could be All dates or anything you prefer.
4. Click the Filter button.
5. Add a Transaction filter that equals to Invoice.
6. Close the Filter window.

By running this report, you can see the total amount for each customer with its sub-customers.

Moreover, you can also consider saving this report so you can access it easily in the future.

Will this include all invoices/invoice amounts using the revenue recognition tool? 

Hi there, Justine. Yes, you can also run a report for the Revenue recognition tool. I can show you the steps on how to pull it up.

If you already have set up your revenue recognition and turned it on, you can track it by running a report.

Here's how:

1. Go to Reports. 
2. Search the Revenue Recognition Report, then click it.
3. Customize the report if needed.
4. Click Run report.
