Hello there, @Ames79.

Thank you for joining the Community. Allow me to help share some insights about adding the Description on the Estimates by Job.

Currently, the option to add the item's description on the report is unavailable. However, you can add a memo to show the description of the report.

Here's how: 

1. On the Estimates by Job report, double click a transaction.
2. On the Estimate page, enter the description on the MEMO field.
3. Click Save & Close. 
4. Select Yes to confirm. 

After you add the memo, you can customize the report to make sure the Memo column is selected. 

Here's how: 

1. At the top left, select the Customize Report button. 
2. Select the Display tab.
3. Under COLUMNS, put a check mark next to Memo. 
4. Click OK. 

I'll make sure to pass your idea to our Product Development team to see if this feature will be available for future updates. You can also send your product suggestions. 

This way, we'll be able to know what product features or options we need to add in the future updates.  To send your feedback, please go to the Help menu, choose to Send Feedback Online, then click Product Suggestion.
