The user interface of this software is very good and easy to understand. It has many features which can be used by any estimator in estimating jobs. This software is highly accurate. I have not found anything what i dislike about it so far. So far no major issues as such but minor ones may arise at times when you are using it for first time or if there is lack of knowledge regarding its functions. We use this software mainly to generate detailed estimates for our customers. it helps us keep track of materials and make sure we do not oversell.
