## The answer, as recorded

Asked on 2026-09-26 through Claude (Anthropic) with web search (model claude-opus-5).

> There's no single winner here - the right pick depends mostly on what you bid. Here's who I'd actually name, roughly in the order I'd shortlist them:
> 
> **1. STACK** - My default recommendation for most small-to-midsize firms. Cloud-based takeoff + estimating, works across nearly every trade (GC, concrete, roofing, interiors, masonry), and it's the cheapest serious option at roughly **$49/user/month**. Strong reputation and review scores. Start here unless you have a reason not to.
> 
> **2. Sage Estimating** - The commercial GC standard, especially if you're already on Sage 100/300 Contractor for accounting. Assembly-based estimating with real database depth and clean handoff to job costing. Expensive - figures reported around **$365/user/month**, or ~$5-8K/year for one seat - so it only makes sense above a certain volume.
> 
> **3. Buildxact** - Best for residential builders and remodelers coming off spreadsheets. Notably, they dropped per-user pricing, so a 10-person team pays the same as a solo estimator: **Foundation ~$169/mo annual, Pro ~$339/mo** with job management and scheduling. Best value if you have several people estimating.
> 
> **4. HCSS HeavyBid** - If you do heavy civil at all -

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.
