STACK
Cloud takeoff and estimating with a free tier and AI-assisted measurement
What is STACK?
STACK is a cloud construction platform combining quantity takeoff, estimating, plan management, and field collaboration for preconstruction through closeout. Premium and Pro tiers add GPT-powered AI chat and optional FloorPlan AI, Aerial Image Takeoff, and ERP connectors. A persistent free Takeoff tier lets estimators measure projects without committing to a paid seat.
Construction, field service, estimating, job management, documentation, and contractor operations tools.

Use cases to evaluate
Performing quantity, labor, and material takeoffs on PDF plan sets
Producing bid proposals with assembly-based estimates
Sharing plan markups, RFIs, and daily reports between office and field
Comparing plan revisions across version drops without manual diffing
Fit to evaluate
Specialty subcontractors bidding high volumes of commercial work
General contractors needing both preconstruction and field tools
Suppliers and manufacturers producing material takeoffs for customers
Estimators who want a free entry point before committing to a paid seat
Business fit
Right for you if you are a GC, sub, supplier, or manufacturer who needs digital takeoff and estimating across many users and want to scale up from a free seat to AI-assisted measurement when ready. Good fit if your team is split between field and office and needs a single plan set with markups and issues. Skip if you only need lightweight markup tools or you have already standardized on a competing assembly-driven estimator like Sage Estimating or HCSS HeavyBid.
How to evaluate STACK
Use this category when jobs, estimates, crews, photos, or project handoffs are hard to manage manually.
Confirm the exact workflow
Map STACK to one concrete workflow first, such as performing quantity, labor, and material takeoffs on pdf plan sets. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Compare estimating, scheduling, field documentation, mobile usability, and reporting.
Compare practical alternatives
Shortlist STACK against Procore, Autodesk Construction Cloud, Bluebeam so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
