Yay!  you added a markup column to ESTIMATES.  Which, by the way are useless in the construction industry.  Unless you're like a one person handyman service.  What if I need to bill a client for additional work performed and material purchased?  Then I need to go to the step of creating an estimate and then creating an invoice from that?  Just silly.  Here's an idea.  ADD A MARKUP COLUMN TO THE INVOICING!  Just like everyone and been screaming for.  Just like the desktop version.  Why this is so difficult?
