First, watching all your tutorials and this software looks great. However, at 27:45 you say its a "margin, not a markup, so this is a percentage of the total cost. So at 20% it would be taking the total cost divided by .8 to get that amount." Which is the correct way to do it... except, $51,013.17/.8 = $63,766.46... and the software is saying $61,215.80 which is the subtotal MULTIPLIED by 1.2 (which most would say is NOT the correct way to do this, but more importantly, what I am seeing and what I am hearing doesn't match up).
