Cant Add Cost column to reports (COGS)

We can run an Inventory Valuation Detail report to track sales made from your account, Aar0nBr. Let me help provide detailed steps so you can add cost columns to your reports.

With the screenshot you've provided, we're unable to add Cost columns to Sales by Customer Detail reports when keeping track of customer sales transactions. 

However, you can consider running the Inventory Valuation Detail report to track inventory sales and product quantities made from each item as a workaround. This also includes individual entry information for each sale from your account. To do this:

1. In your QBDT account, go to Reports and click on the Inventory dropdown.
2. Choose Inventory Valuation Detail report.
3. Click Customize and enter Cost from the Columns section.
4. You may add and customize other details and specify filters on your reports.
5. Review all data, then click OK.

Moreover, you can utilize this guide to help you save all the customizations made on your reports: Create, access and modify memorized reports.
