Hi martinmorelmecha,

Welcome to Community!  QuickBooks Online provides a wide range of reports, so you can view specific areas of your books.  I would be glad to provide some insight here!

If you've set up your labour costs as a service, to be added to your invoices, I recommend taking a look at the Sales by  Product/Service Detail report.  You'll want to select the Report period, then open the Customize option.  In this area, you'll be able to Group by product/service and select specific filters.  When you hit Run report, your items will be grouped accordingly, with the totals for each product/service.

Feel free to reach out again, if you have other questions.  We would be happy to help!
