STACK
Verdict: The safest general pick for a small or mid-size sub: one browser tool from plans to proposal.
Cloud takeoff and estimating, from STACK Construction Technologies. Vendor site
Who it’s for
Subcontractors and suppliers in most trades who want takeoff, estimating and proposals in a browser, with nothing to install.
Who should skip it
You bid one specialized trade whose documents (a door schedule, a hardware set) need reading together rather than measuring.
Strengths
- Takeoff, estimating and proposals in one cloud product
- AI takeoff, plan organization, advanced plan search and version compare listed on the vendor's site
- Trade tools and custom items and assemblies
- Excel and ERP connectors for the pricing you already keep
Limits
- General-purpose: trade logic beyond measuring and counting lives in your assemblies
- No independent security audit named on the pages we read; ask for one
