Commercial construction estimating is all about accuracy and details. You expect any estimating system to be accurate and they must be. But what we mean by accuracy is not just 2 + 2 = 4, what we are referring to is very complex calculations to arrive at a final number that can be trusted!
EasyEst Estimating Software has very complex number crunching going on in the background almost all the time and you can go to the back with these totals.
Regarding details, even if you sub-contract most of your work out, you can control each subcontractors applied overhead and markup to give you very precise cost allocation for each job. Many estimating systems only allow global percentages to be applied to materials, labor and equipment.
