The answer, as recorded

There's no single "best" - the right pick depends on what you build and how big you are. Here's how I'd rank them: **1. STACK - the default recommendation for most firms.** Cloud-based takeoff + estimating that works across nearly every trade (GC, concrete, roofing, drywall, landscape, interiors). Easy to onboard, good collaboration, and it's the one most people land on if they don't have a specialized need. Roughly $2,500-$3,000/user/year, which is the main knock against it - it's pricey for a single-seat shop. **2. PlanSwift - best value for desktop takeoff across trades.** Cheaper than STACK, extremely flexible, and their Takeoff BOOST AI tooling automates a lot of the manual measuring. Good if you want a bid-focused tool rather than a whole platform. **3. Sage Estimating - for established commercial GCs.** 30+ years in the market, handles the full workflow from digital takeoff through bid submittal, and pairs naturally with Sage 300 CRE if you're already on Sage for accounting. This is the "we do $20M+ in commercial work" answer. **4. HCSS HeavyBid - if you do heavy civil or DOT work.** Genuinely the category leader for infrastructure bidding: codebooks, reusable labor/equipment/material cost buckets, multi-phase jobs. Integrates with QuickBooks and Sage 300. Don't buy a general-purpose tool if this is your work. **5. Trimble Accubid (Classic or Anywhere) - if you're an MEP subcontractor.** Spec-driven engine: define your specs once and it auto-applies the right materials and labor during takeoff. Electrical and mechanical contractors consistently pick this over generalist tools. **6. Clear Estimates or Buildxact - for residential builders and remodelers.** Clear Estimates starts around $79/month with a prebuilt cost database, so it's the realistic step up from spreadsheets. Buildxact targets the same small-residential segment. **7. Bluebeam Revu - if your workflow is already PDF-heavy.** Not a full estimating system, but excellent for quantity takeoff and markup, and many estimators use it alongside a separate pricing tool. **8. Procore Estimating - only if you're already on Procore.** It integrates tightly with their PM, financials, and field tools, which is the whole argument for it. But it's sold in modules and lands around $15K-$50K+/year - hard to justify purely for estimating. Two practical notes: budget for **RSMeans** cost data as a separate line item if you don't have solid historical numbers of your own; and note that Buildertrend has stopped publishing prices and now routes you through a sales call, as has Procore - so get quotes in writing before you compare.
