Thank you for reaching out to the Community, @bdesilva. I’ll guide you through customizing your report in QuickBooks Online (QBO).
We can customize the Sales by Product/Services Detail report to show the cost field of the item. I’ll show you how:
- Click Reports.
- On the search field, enter Sales by Product/Services Detail.
- Click the Gear icon on the upper-right side of the report.
- Click the Show more link.
- Put check mark on Amount box.
- Click on your screen to refresh the report.
