I had a problem with McCormick Systems Estimating and called McCormick to fix problem. McCormick would not help me unless I agree to one year support @ $650. I had I bid that I was working on and could not finalize. I offered to pay for the time it would take to fix problem. McCormick Systems would not work with me that way. I went ahead with the year support. The problem took 20 minutes to fix. I ask all contractors is this anyway to treat customers. McComick caused me a lot of duress over this and I would not want to see anyone else go thur the same.
