Seriously, this isn't an answer to this common need for any business that resells buyouts. 

Create the estimate, email it, then update it? Create a new service *every* time I want to add markup to a buyout expense? Please. Could it be less efficient?

I demand to know why QBO can't match QB desktop's option to add markup to a buyout expense, have the client see only the final estimated cost, and track the markup income. Just give us the column back as it was in desktop and make everyone's work easier.
