Hi APS4,
Thanks for posting in the Community!
Let's go ahead and run the Profit and Loss by Customer in QuickBooks Online and customise the report from there. Here's how:
- Log in to QuickBooks Online.
- Click on the Reports tab.
- On the search box, type in Profit and Loss by Customer.
- Select a report period and accounting method.
- Click on on Customise button to add Filter like selecting a specific Customer.
- Click on Run report.
Expenses will not show any figure if the selected customer/vendor does not have expense transaction created for them.
