Thank you for responding, @Aar0nBr. Including the option to display sales reports by cost provides a direct way to assess the profitability of your business.

Currently, adding a Cost column in the Sales by Customer Detail report or generating calculated fields is unavailable in QuickBooks Desktop.

These functionalities would be valuable additions to the program. Therefore, I recommend providing feedback about this feature to our developers. They can review your suggestion and potentially include it in future updates.

Here's how to send your request:

1. Click on the Help option in QuickBooks Desktop.
2. Choose Send Feedback Online.
3. Select Product Suggestion from the options provided.
4. Enter your feedback suggestion.
5. Click the Send Feedback button to submit your suggestion.

This process ensures that your input reaches the developers for consideration in improving future versions of QuickBooks Desktop. In the meantime, you can run the Inventory Valuation Detail report to add the Cost column.

If the report you need isn't readily available, you can also try to create and customize reports for the following:

• Customer, job, and sales reports
• Vendor reports
• Item reports
• Company and financial reports

If you have any further questions or suggestions regarding adding a Cost column to the sales report in QuickBooks, feel free to share them on the QuickBooks Community page. We're here to assist you.
