Groundwork Takeoff vs STACK · July 2026

A genuinely good cloud.
At $3,000 a seat, tethered to WiFi.

STACK built a polished cloud takeoff platform — real collaboration, big item libraries, well-rated support. It also costs $2,988–$3,588 per seat per year, has no offline mode, and sells its AI as a separate add-on. Here's the honest side-by-side.

TL;DR: Choose STACK if you want a mature browser-only platform with deep prebuilt libraries and Procore/Acumatica integrations, and your team always has fast internet. Choose Groundwork Takeoff if you want native-app speed on Mac and Windows, real offline work, full takeoff on iPad, AI included on every seat, and the same real-time collaboration — for $950/yr instead of $2,988. That's $2,038 per seat, per year saved against STACK Premium alone.

What STACK users
tell us at renewal time.

"Every year the subscription cost goes up, but our team only utilizes the basic takeoff tools."— Verbatim from a Capterra review. At $2,988–$3,588 a seat, you're funding the whole platform whether you use it or not. Groundwork is one price: $950, everything included.
"Big multi-sheet set, mid-takeoff, and the browser starts crawling. Sometimes it's too slow, or freezes — and there's nothing to do but wait."— Lag on large plan sets is the #1 complaint in STACK's Capterra reviews; 66% of negative Software Advice reviews cite connection speed. Groundwork renders natively on your machine.
"The jobsite trailer has one bar of signal. STACK has no offline mode, so my takeoff stays in the office. The iPhone app? View-only."— No offline mode is a top STACK user request, and mobile takeoff is read-only. Groundwork is offline-first with a 14-day grace period, with full takeoff on iPad.
When STACK wins

We'll say it plainly.

STACK is a polished, mature cloud product: SOC 2 certified, 4.5/5 across 1,300+ Capterra reviews, support scored 9.5 on G2, huge prebuilt item and assembly libraries, and native integrations with Procore, Acumatica, and Excel. If those integrations anchor your workflow and connectivity is never a problem, STACK is a credible choice.

But if the question is speed, offline reliability, and price — measuring big plan sets fast, from anywhere, without a $2,988 invoice — Groundwork does the takeoff-to-estimate job natively, on every platform you own, for $950 a seat.
