Hello there!

I understand that you really need to have the markup feature on estimates. Let me assist you with this.

Currently, the markup in QuickBooks Online can only be added to the invoices when you add billable expenses to it. The best option I can suggest for now is to create a service item and add it to your estimates.

Also, please send feedback to our engineers about this feature. The more requests they receive, the more chances it'll be prioritized. Go to the Gear icon, and select Feedback.

In addition, you can check this article: Enter billable expenses. This will show you the detailed steps on how to record and track billable expenses if you need help.
