The Sales by Customer report never shows any data. I have this problem across multiple companies, and I've tried using different browsers. Extremely frustrating.

I hear you, @DirkDoncic.

Before we can accomplish your goal for today, may I ask for more info about your report? Can you tell me the name of the sales by customer report and how you customize it? Or did you perhaps receive an error while generating the report data?

A screenshot would be helpful and will gladly be appreciated. Keep me updated in the comments below. Hope to hear from you soon. Take care always!

The name is "Sales by Customer Summary." It's just a default Quickbooks Online report. I customized nothing. 

No matter the date range, all it says is "This report does not contain any data." It's extraordinarily frustrating, and customer service did nothing to help me.

This is not the kind of impression I’d like you to have, @DirkDoncic.
