I sat through a one day seminar on how to use it and purchased it. I thought it looked like a decent piece of software. I haven't used (and should have returned when I could have) because I realized my company was losing money with the way I was running it and decided to change my focus from trying to land larger commercial work to scaling down and becoming more efficient.
I can't say if the learning curve was too large compared to other software. It would be great if I was a full time estimator. I bought the little scale roller that plugs into the USB. The only thing is, you'd have to take a couple of jobs you've already tracked and job-costed, and plug them in to see how it compared to the software as far as percentage mark-ups and profit. Once some of the variables got dialed in to where you are used to, it could be useful, but I would only recommend if you are going to be doing ALOT of bidding.
The other thing, I was not used to bidding so methodically like the software demands. (counting every pipe run, every conductor, every strap, every fitting). I guess it's not a bad way to go, I just hadn't done it that way in the past. But if I had mastered the software, it does make it easy to split the job into gear, fixtures (or luminares), etc.. You don't have to use it the way it wants to be used.
Also, it allows you to break the job out and look at different ways once you've done all the input.
Hope this helps. good luck
