STACK vs. zzTakeoff
Built for Estimating Professionals, not just Takeoffs.
zzTakeoff might cover the basics, but STACK delivers the depth, flexibility, and proven reliability today’s teams need, combining powerful estimating, cloud collaboration, and AI-driven efficiency in one mature, secure platform.
Smarter Tools. Stronger Bids.
STACK’s powerful estimating flexibility and smarter takeoff tools outperform zzTakeoff at every turn.
Integrated Estimating Capabilities
STACK
Easily generate detailed cost estimates by including labor, material, and equipment costs directly to takeoff quantities.
zzTakeoff
No built-in estimating available. No native labor, material, or assembly costing. Takeoff updates don’t roll through to estimates.
Why does it matter?
With STACK, you’re not just measuring—you’re managing the entire preconstruction process in one platform.
Takeoffs That Work the Way You Do
STACK
Powerful, customizable takeoffs with AI-assisted measurements, labeling, grouping, and full assemblies capabilities.
zzTakeoff
Only offers limited takeoff types. No grouped measurements, no linear with drops, and no material and labor assemblies.
Why does it matter?
More flexibility means less manual work—and fewer costly errors.
Count and Area Tools
STACK
90+ symbol options. Size control and rich visual customization.
zzTakeoff
5 symbol options and very limited visual options.
Why does it matter?
Don’t compromise your workflow because of system limits. STACK adapts to your needs.
Project Management That’s Actually Manageable
STACK
Seamless project organization with global folders, tags, and layers. Includes built-in OCR scanning and automatic sheet hyperlinking.
zzTakeoff
Folders and layers exist—but they don’t integrate across all lists. No OCR scanning or hyperlinking.
Why does it matter?
Organized projects make onboarding faster, revisits easier, and team handoffs smoother.

Frequently Asked Questions
STACK offers more powerful features – including AI accelerated takeoff, greater and integrated estimating. It’s cloud-native, built on a scalable, proven infrastructure, boasts enterprise grade security to keep your data safe and its open API ecosystem is designed to connect to your most important business systems. STACK is experienced and here to support your growth, not a startup focussed on our own momentum.
Not at all. Most users are up and running in hours—not days—and our training and support teams are here to make your transition seamless.
Yes. With STACK, multiple users can work on the same project at the same time, from anywhere. Plus, our multi-user roles and permissions help to keep project data and visibility organized just the way you need it – zzTakeoff simply can’t do that.
STACK’s AI speeds up plan recognition, auto-labeling, and measurements—saving time and reducing errors before you even lift a mouse.
Absolutely. While zzTakeoff may appear cheaper upfront, it lacks the depth, speed, and productivity gains that STACK delivers—meaning more wins, faster bids, and higher profits.
