Great product, easy to use, easy to learn. My entire estimating workflow is more efficient because of STACK. I am able to bid more projects in less time. Because STACK is Web-Based I can use it on any computer. STACK works on both my PC and MAC. I recommend STACK to the other subcontractors I work with.

What makes STACK stand out to me is the open architecture. STACK’s application programming interfaces, which allow us to integrate other systems into STACK, are unique. One of the really exciting things about STACK is that we go from being rigid and inflexible to being able to quickly respond to customers.
