When preparing comparison reports between 3 tab and laminated shingles you have to go in and duplicate to the letter every step to correct a proposal. Which is tedious and difficult to remember when you have several changes. Why can't you have a master sheet to verify quantities and changes that feeds the proposal. Then the comparison's are 100 % accurate and easier to manage. I am not comfortable sending out comparisons the way it is set up. Too many opportunities to make mistakes on the existing platform which is unstable at best as you make changes due to it always changing up the scope order every time you make a change.
