We realized STACK's AI feature would be a big asset to speeding up our process. The more we can put out, then the more likely we are to win. It's AI, you still have to vet it, but I would not hesitate a second to use it."

We really like STACK for our insulation and specialties subcontracting company. Quick and easy to use! Integrates with Google Drive for uploading plans. Love that it can be used from anywhere.

If I said we’ve increased efficiency by 1000% you would think it was a typo, but really there’s no way to measure the time savings – it’s a lot more than 40%. The features that have been added to STACK over the years have been so focused on productivity and enhancement of the takeoff process. I couldn’t do it without STACK.

STACK has increased my productivity and probably made me twice as fast just with the developments and improvements that have been made. Working from the cloud has given us the ability to help each other and collaborate, strategize more seamlessly, land more bids, and save time.

STACK has improved our win rate by 10-15%, and a big part of it is being more accurate. It's very easy to use and allowed me to capture everything more precisely.

Been using STACK for 3 months now and I can say the program is so intuitive to use. I was up and running with my own personal customization in 30 days. That's progress over other programs. And the technical support team is awesome. I don't have to create a spreadsheet for the estimating. STACK does this for me and the calculations are spot on. If they are not, it's usually something I did wrong.

STACK is extremely intuitive, very easy to setup and even easier to use. We've been using it for almost 8 years now and have yet to find anything we don't like about it. As they continue to update the software and add features it's becoming even more user friendly and allows us to complete takeoffs even faster and with greater accuracy.

As an Estimator working both in and out of the office, the ability to log in from any location is the best feature that I enjoy from STACK. Along with the shared files with co-workers, makes collaboration a seamless process.

Fast, easy, and convenient to use without any hassle.

STACK has helped us streamline our estimating process. We are a small HVAC/Plumbing business and using STACK has made our estimation process smoother. We used to do everything long hand and enter it into excel manually. The ability to take everything off digitally and manipulate the takeoff either within STACK or exported to an excel document has made the takeoff process much easier. What used to take me all day to do is now easily able to be done in a few hours.
