A great feature for your app would be if you could search invoices by product. So you could see a list of people who purchased a particular product. Can you do that?

Glad to have you hear, Sgk1.

You can generate a report called Sales by Product/Service Detail. You can also customise this report if you wanted to see the list of customer who purchased a particular product. 

To do that: 

1. Go to Reports tab.
2. Search for Sales by Product/Service Detail.
3. Select Customise. 
4. Select Filter. 
5. Select a Product/Service on the drop-down menu.
6. Select Run report. 

Feel free to check on this article to see the reports included in your QuickBooks Online subscription.
