The customer service from Constructor has been fantastic, they are always willing to help me out when I need it! It's very easy to use as well. There isn't much that I dislike about this program. If you're looking into purchasing a new estimating or accounting system then definitely look at constructors products. They have helped us improve our business so far and we haven't found anything yet that hasn't worked perfectly. We no longer spend time entering data manually which saves us hours of work each month.
