Very friendly to the end user setting up and the easiness of using every day. It's hard to say what I like best about this estimating software, it was described from FastEst that you can build and modify the software to fit your company and estimating style building you own personable library of Job Items, Assemblies, Specs, PFV coloring, end of job reporting mods and the take-off screen lay-out is very well thought out also. Great group of people starting from the reception desk which are friendly and helpful to the tech desk which so far has been helpful & friendly also in every aspect answering questions such software, modifications, building your library, tips to do things easier, IT issues and the willingness to stay with you to get things worked-out when you have a problem or idea.
