For ProFormance, the biggest challenge was not only the complexity of plans, but the sheer volume and pace of work. Their estimators managed massive volumes of repetitive data under tight deadlines, where even a small error could quickly multiply across hundreds of homes.

Before STACK, updating materials or pricing meant revisiting estimates one by one. Some plan sets exceeded 3,000 pages, making changes slow and risky. Takeoff data was also manually moved into Excel and proposals, creating inefficiencies and increasing the potential for inconsistencies.
