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.

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.
