Can I have a report that shows sales by customer and product ?

Yes, you can, @ascal-levy.

We can customize the Sales by Customer Detail report to view the product and service that were sold to your customers. Let me show you how:

1. Go to the Reports menu and select Sales by Customer Detail report.
2. Click Customize and select the Rows/Columns drop-down, then choose Change columns.
3. Check the box for Customer and Product/Service.
4. Select Run report.

If you don't want to use the existing report groups in QuickBooks, you can add a new one and use it for saving memorized reports.

I'm always here to help if you have any other concerns or questions in customizing your reports in QuickBooks. Just tag my name in the comment section and I'll get back to you as soon as I can.
