## The answer, as recorded

Asked on 2026-10-05 through Claude (Anthropic) with web search (model claude-opus-5).

> There's no single "best" - estimating software splits hard by what you build. Here's who I'd actually name, by segment:
> 
> ## Commercial GC / multi-trade
> 1. **STACK** - my default recommendation for most commercial GCs and subs. Cloud-based, runs on Mac or PC, strong on-screen takeoff that flows straight into an estimate and a bid-ready proposal. The learning curve is days, not months, and it's the one most people land on without regretting it. ([constructioncoverage.com](https://constructioncoverage.com/estimating-software), [capterra.com](https://www.capterra.com/resources/best-construction-estimating-software-reviews-analysis/))
> 2. **Procore Estimating** - worth it only if you're already on Procore or heading there. The estimating module itself isn't best-in-class, but having takeoff, PM, financials, and field data in one system eliminates the re-keying that kills most estimating workflows. Expensive, and priced on construction volume. ([gobridgit.com](https://gobridgit.com/blog/construction-estimating-software/))
> 3. **Trimble (ProEst / ProjectSight)** - ProEst combines cost estimating, digital takeoff, and bid-day analysis in one place; good fit for firms that want a real cost da
