Hello,  I am about to invest money into a new computer, upgrade to the new version (SSA over lapped) and build an office (starting up new business). The main thing I want to offer my customers is Estimating Materials (List). Is there anyone out there doing this with Chief Architect? If you are. How accurate do you find the program? How difficult is it to set up the build in order to calculate the materials? Can anyone offer me any tips or suggestions?
