Can I automatically add a markup to my quotes/estimates?

Yep, you can add a markup at the price list level and can then override or delete that value at the area level. Be sure to only set a default margin OR markup for a price list.

The Markup % in the area module is set once the price list has been selected

The markup value is applied to the calculated unit revenue based on the cost definitions for each line item.
