Groundwork Takeoff vs On-Screen Takeoff · July 2026

A classic.
And it drives like one.

On-Screen Takeoff practically invented digital takeoff — in use since 1995, deep multi-condition workflows, a loyal base in the commercial interior trades. It's also Windows-only, converts your drawings to TIFF, sells estimating as a separate product, and won't publish a price. Here's the honest side-by-side.

TL;DR: Choose On-Screen Takeoff if you're a commercial interiors contractor whose whole bid pipeline runs through OST + Quick Bid + eQuotes and it's working — that workflow is genuinely deep. Choose Groundwork Takeoff if you want takeoff and estimating in one modern native app on Mac and Windows, a public price ($950/yr, everything included), AI on every seat, and no quote-only sales cycle or auto-renewal fine print.

What longtime OST users
tell us in 2026.

"The interface is at least a decade out of date — clunky and non-intuitive. New estimators take weeks to get comfortable, and known issues sit unfixed."— Composite of documented Capterra complaints: "at least a decade out of date… clunky and non-intuitive," with reviewers citing slow vendor response to known issues.
"Three hours into a big bid, the database crashed and took the takeoff with it. On large jobs it bogs down until you're waiting on every click."— Capterra reviewers report that databases can crash, losing hours of work, and that OST bogs down on large bids. Groundwork saves continuously with an offline-first store.
"We tried a discounted trial, then found the renewal: a dramatic price increase, auto-renewed, cancellable only in writing 30 days before the date."— Sales and renewal practices documented in ConstructConnect's BBB profile and Trustpilot reviews: auto-renewal requiring written cancellation 30 days prior, and discounted trials that renew at sharply higher prices.
When On-Screen Takeoff wins

We'll say it plainly.

OST has a 30-year track record — the first digital takeoff software, in use since 1995 — and it shows in the good ways too: deep multi-condition takeoff, a proven plan overlay, and real strength in commercial interior trades like drywall and walls & ceilings. Paired with Quick Bid and eQuotes supplier pricing, the full ConstructConnect workflow is genuinely deep, and its loyal users know every corner of it.

But if you're starting fresh — or tired of TIFF conversion, Windows-only installs, quote-only pricing, and estimating sold as a second product — Groundwork gives you the whole takeoff-to-estimate pipeline in one modern app, with the price printed right on the website.
