STACK for Excel has been a game-changer for our estimating process. Because we bid work as entire communities rather than one project at a time, this feature has eliminated hours of repetitive data entry. We’re saving roughly four hours per day across our estimating team alone. On top of that, our Excel-based proposal workflow now feeds directly into our process, which has significantly sped up proposal turnaround for our inside sales team. The result is faster bids, faster proposals, and a much more efficient operation overall.

I really appreciate the accuracy that STACK Takeoff & Estimate provides, especially how it clearly depicts materials takeoffs. This clarity is vital because it allows us to share detailed and reliable information with our customers effortlessly. I also find that the software enables us to get accurate material quantities promptly, which is crucial for landscape and hardscape construction projects. Moreover, the ease of use and user-friendly learning curve of STACK Takeoff & Estimate means that integrating it into our workflow was seamless and straightforward.

I use STACK Takeoff & Estimate to perform takeoff on my projects. I find it great for getting all the information in one place without needing to print blueprints. It's very user-friendly and affordable, which is a big plus. For my needs, it works very well and has a function for every part of the bidding process. The initial setup was very easy too.

I’d never done an estimate in my life, and had just taken over my in-laws’ lumber yard. A contractor walked in needing takeoffs done on a new house. I found STACK. It took three days, but I was able to get the estimate out the door. I’ve since gotten faster, and don’t have to burn the candle at both ends, but STACK saved my bacon on that gig. I’ve sung its praises ever since.

Efficient Bidding with STACK's AI-Driven Precision

I have a high appreciation for STACK Takeoff & Estimate because it effectively meets our needs for takeoffs and estimating, which made it stand out among other vendors we considered. The setup process was straightforward, facilitated by comprehensive training, which made using the system easy despite initial concerns. The standout feature is the AI software, which has greatly enhanced our efficiency by automating the tracing of walls and lines, substantially speeding up our workflow. This feature also empowers us to handle a higher volume of bids, thereby increasing our capacity to secure more jobs. Additionally, the ability to save material costs within the system is tremendously helpful. Even though the AI is pricey, the increase in productivity and the workload it enables us to handle makes the cost worthwhile. Overall, STACK Takeoff & Estimate effectively eliminates the manual hassle of calculations, making our bidding process much more efficient.

I use STACK Takeoff & Estimate to create takeoffs for large multifamily apartment buildings. I like being able to view the buildings in a way that allows me to edit the takeoffs easily. The initial setup was very easy. It solves the problem of tracking materials.

STACK's Al has helped me tremendously on projects where I get a massive floor plan and there's just so many variables in rooms. I use the Al feature and it just encompasses everything on that floor. You can pick and choose what you want to save, keep, and move to a particular Assembly or Item. What would take 2 hours you can do in 5 minutes.
