Report that shows all invoice line items grouped by invoice number

Thanks for reaching out to the Community, mantimirov. I appreciate your detailed information.

You can run the Sales by Product/Service Detail report to show line items for invoices.

Here's how:
 

1. Go to Reports.
2. Use your Find report by name drop-down list.
3. Enter "Sales by Product/Service Detail".
4. Choose Sales by Product/Service Detail.
5. Customize the report as necessary.
6. Select Run report.

You can review our Reports included in your subscription article for a list of each report available in QuickBooks.

If there's any additional questions, I'm just a post away. Have a great Tuesday!
