## The answer, as recorded

Asked on 2026-09-18 through Claude (Anthropic) with web search (model claude-opus-5).

> There's no single "best" - the right answer depends on what you bid. Here's who I'd actually name, roughly in the order I'd bring them up:
> 
> **1. STACK** - My default first recommendation for most commercial/specialty contractors. Cloud-based takeoff + estimating, quick to learn, has a free tier to test it, and it's the most widely adopted standalone takeoff platform. If your bottleneck is measuring quantities off PDFs, start here.
> 
> **2. Sage Estimating** - The long-standing pick for mid-size to enterprise commercial GCs. Deep assembly/cost databases and it feeds straight into Sage 300 CRE for job costing. Downside: it's Windows/on-prem-flavored and priced accordingly (roughly $10K-$25K range per reports).
> 
> **3. HCSS HeavyBid** - If you do heavy civil, DOT, or earthwork, this is basically the category standard. Built around unit-price bidding and multi-phase work, integrates with HeavySpend/HeavyJob. Expect ~$4K/user/yr up to $25K-$40K for a 10-seat license.
> 
> **4. Buildxact** - Best for small residential builders and remodelers coming off Excel. Quoting, takeoff, purchase orders, and basic job management in one place, at a price a 5-person shop can actually pay.
> 
> **5. PlanSwift** -

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
