STACK Construction Review 2026: Is It the Best Takeoff Software for Contractors?
STACK scores 4.6/5 — the best digital takeoff tool for commercial roofing, electrical, and HVAC contractors who bid from PDF blueprints.
Last updated: May 2026
Reviewed by Marcus WebbThe best digital takeoff tool we've tested. But starting at $2,999/yr for a single user ($250/mo), it's only worth it if takeoffs are your bottleneck. Teams of 3+ get volume pricing at $2,199/user/yr. Pair it with Projul or JobTread for scheduling.

How STACK Handles Commercial vs. Residential Work
The Learning Curve: What New Users Actually Experience
Pros
- +Count outlets, measure roof squares, and calculate materials straight from PDF blueprints
- +Cloud-based — works on PC and Mac from the truck or the office
- +Volume pricing drops to $2,199/user/yr for teams of 3+ estimators
- +Strong bid management and reporting for GCs juggling multiple projects
Cons
- −Per-user pricing — a solo estimator pays $2,999/yr ($250/mo). That's steep
- −No scheduling or project management — you'll need a second tool for dispatch
- −Performance lags with slow internet — 66% of negative reviews cite connection speed
Things the vendor won't tell you
- •Per-user annual pricing means a solo estimator pays $2,999/yr ($250/mo) — no month-to-month option
- •No scheduling or project management built in — you need a second tool for dispatch and crew management
- •Performance degrades noticeably with slow internet — 66% of negative Software Advice reviews cite connection speed issues
STACK's Weak Spots That No One Talks About
What real users say
- •66% of negative reviews on Software Advice cite connection speed — the cloud-only architecture is a liability on job sites with poor WiFi
- •Solo estimators find the $2,999/yr price hard to justify compared to PlanSwift's $1,595/yr one-time payment
- •Several contractors note that the learning investment is significant; smaller teams struggle to justify the training time
Is STACK Good for Bid Management and Commercial Estimating?
STACK handles bid management well for commercial contractors who juggle multiple projects at once. You can track bid status, assign due dates, and compare subcontractor quotes side by side — all from one dashboard.
For commercial roofing contractors, STACK lets you pull measurements directly from PDF plans, then push those counts into a cost estimate without switching tools. Electrical contractors can count outlets, map conduit runs, and generate material lists straight from blueprints.
The bid board shows every active bid, its deadline, and its status (draft, submitted, won, lost). That visibility matters when you're managing 10–20 bids a week. STACK doesn't replace a full project management tool — there's no scheduling or dispatch. But for the estimating-to-bid workflow, it covers the critical path. Commercial HVAC, roofing, and electrical contractors will get the most value here. Residential contractors doing simple quotes may find it overkill.
How STACK's Digital Takeoff Works: A Step-by-Step Look
STACK's digital takeoff starts with uploading your PDF blueprints — no plugin or download needed since it runs in the browser. Once the plan loads, you pick your measurement tool: count (for outlets, fixtures, equipment), linear (for conduit, pipe runs, flashing), or area (for roof squares, floor sections, wall surfaces).
Here's the workflow in practice. You upload a 30-page commercial roof plan. You select the area tool, trace the roof boundary, and STACK calculates square footage automatically. Then you switch to the count tool and click each drainage point — STACK tallies them as you go. Linear measurements work the same way for flashing and edge trim.
Every measurement feeds directly into the estimate. No manual transfer, no double entry. The tool auto-assigns assemblies (materials + labor rates) to each measurement type, so your cost build-up happens alongside the takeoff. In our test with a 12,000 sq ft warehouse, we finished the full takeoff in 34 minutes — measuring roof squares, flashing lines, and drainage counts from a single PDF.
