Can I generate an estimate report for last month by class?

Welcome and thanks for reaching out to the Community, @martin33.

In QuickBooks Online (QBO), the ability to pull up an estimate by class is currently unavailable. You can refer to this article to see the list of reports that you can run by class: Run reports by class.

I can see how having this option would be helpful for you and your business. Rest assured that I'll pass along your suggestion to our Product Developers. They're always looking for ideas to consider on how to improve QBO.

In the meantime, I recommend visiting our Blog site. This is where we share recent happenings and future developments, such as updates to newly added features.

Please let me know if you have any other questions or concerns. I want to make sure everything is taken care of for you. I'm always here to assist. Have a wonderful rest of the day!
