The question asked, verbatim: best estimating software for construction firms

Brands named, in the order the engine gave

1. STACK recommended
   STACK - My default recommendation for most commercial GCs and subs.
2. Commercial GCs recommended
   STACK - My default recommendation for most commercial GCs and subs.
3. Procore mentioned
   Cloud-based takeoff plus estimating in one tool, genuinely easy onboarding, customizable assemblies and cost libraries, and it integrates with Procore, Buildertrend, and QuickBooks.
4. Buildertrend mentioned
   Cloud-based takeoff plus estimating in one tool, genuinely easy onboarding, customizable assemblies and cost libraries, and it integrates with Procore, Buildertrend, and QuickBooks.
5. QuickBooks mentioned
   Cloud-based takeoff plus estimating in one tool, genuinely easy onboarding, customizable assemblies and cost libraries, and it integrates with Procore, Buildertrend, and QuickBooks.
6. you're mentioned
   Sage Estimating - The heavyweight for commercial GCs doing detailed, database-driven estimates, especially if you're already on Sage 300 CRE or Intacct for accounting.
7. HCSS HeavyBid mentioned
   HCSS HeavyBid - If you're heavy civil - DOT work, earthwork, utilities, multi-phase bids - this is the category standard and not a close call.
8. PlanSwift mentioned
   PlanSwift - Desktop, and that's the point: fast, flexible multi-trade takeoff that works offline, with estimating built in so you're not buying two tools.
9. Autodesk mentioned
   Autodesk Construction Cloud (Takeoff) - Pick this if you're already in the Autodesk ecosystem and working from BIM models.
10. Buildxact mentioned
    Buildxact - For small residential builders and remodelers coming off spreadsheets.
11. ProEst mentioned
    ProEst (now part of Autodesk) - Mid-size GCs wanting more structure than STACK with less weight than Sage.

The answer, as recorded

There's no single winner - the right pick depends mostly on what you build and how big your estimating team is. Here's who I'd actually name, in order: **1. STACK** - My default recommendation for most commercial GCs and subs. Cloud-based takeoff plus estimating in one tool, genuinely easy onboarding, customizable assemblies and cost libraries, and it integrates with Procore, Buildertrend, and QuickBooks. It's the one most firms can roll out without a consultant. Roughly $1,800-$3,600 per estimator per year depending on tier, and there's a free tier to test first. **2. Sage Estimating** - The heavyweight for commercial GCs doing detailed, database-driven estimates, especially if you're already on Sage 300 CRE or Intacct for accounting. Deepest cost databases and assembly logic of the mainstream options. The catch is cost and friction: ~$3,500+ per license, plus implementation that commonly runs $15,000-$30,000 and 20-80 hours of paid configuration. Only worth it if estimating is a real department, not one person. **3. HCSS HeavyBid** - If you're heavy civil - DOT work, earthwork, utilities, multi-phase bids - this is the category standard and not a close call. ~91% satisfaction across 600+ reviews, strong 24/7 support, and it pairs with HeavyJob for field cost tracking so your bid and your actuals live in the same system. Priced out of reach for most small specialty subs. **4. PlanSwift** - Desktop, and that's the point: fast, flexible multi-trade takeoff that works offline, with estimating built in so you're not buying two tools. Good fit for multi-trade estimators who want a one-time-ish purchase and don't need real-time collaboration. Trimble has been steering customers toward its cloud products, so check the roadmap before committing. **5. Autodesk Construction Cloud (Takeoff)** - Pick this if you're already in the Autodesk ecosystem and working from BIM models. It quantifies from both 2D sheets and 3D models and connects directly to Docs and Build, so quantities, drawings, and project data stay unified. Weaker as a standalone cost-estimating engine than Sage. **6. Buildxact** - For small residential builders and remodelers coming off spreadsheets. Cheapest and simplest of the bunch, quick onboarding, quoting and takeoff together. You'll outgrow it if you move into commercial work. **7. ProEst** (now part of Autodesk) - Mid-size GCs wanting more structure than STACK with less weight than Sage. ~$2,400-$4,800 per estimator/year, but like Sage it typically carries paid configuration hours, so budget beyond the license. My practical advice: if you're a commercial GC under ~$50M and don't already run Sage accounting, start with STACK and a paid pilot on one real bid. The failure mode with Sage and ProEst isn't the software - it's firms buying a database-driven system and never finishing the cost library setup. One caveat on sources: several "best of 2026" listicles rank their own product first (Bidi Contracting, Projul, and similar). I've left those out and named only tools with independent review volume behind them.
