The short version

  • Only STACK Construction Technologies has a free tier, so it costs nothing to try first.
  • Each has a real cost: B2W Estimate pricing is not published anywhere, and the quote depends on estimator seats plus which of the four other B2W modules you take, so like-for-like comparison with HeavyBid or spreadsheets is impossible without going through a sales cycle; STACK Construction Technologies takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • They diverge on capability: B2W Estimate covers Production-rate estimating, STACK Construction Technologies covers Digital takeoff.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

B2W Estimate

  • Pricing is not published anywhere, and the quote depends on estimator seats plus which of the four other B2W modules you take, so like-for-like comparison with HeavyBid or spreadsheets is impossible without going through a sales cycle
  • The system is worthless until your own crews, equipment and production rates are loaded, which is typically several months of a senior estimator's time before the first bid comes out
  • It is aimed squarely at heavy civil self-performing work, so a general contractor whose bids are mostly subcontractor quotes gets very little from the production-rate engine
  • The Trimble acquisition means the product now competes internally with other Trimble civil estimating assets, and buyers should ask directly about the long term roadmap for overlapping products before signing a multi-year term
  • Reporting outside the Inform module is limited, so organisations that want bid analytics across years typically end up buying another module or extracting to a warehouse

STACK Construction Technologies

  • Takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • The full platform combining takeoff, estimating and field management starts at $298 per user per month
  • Field and project management is sold as a separate Build and Operate product starting at $49 per user per month rather than bundled with takeoff
  • The Build and Operate product offers only a two-week free trial, with the free version limited to Takeoff and Estimate

Answered from the vendors’ own pages

B2W Estimate: Is B2W Estimate still sold under its own name?

Yes. Trimble acquired B2W in 2022 and continues to sell it as B2W Estimate within the Trimble Construction portfolio.

STACK Construction Technologies: How much does STACK Construction cost?

STACK costs $49 to $298 per user per month depending on the plan. Build & Operate starts at $49/user/month, Takeoff & Estimate at $249/user/month, and Full STACK Platform at $298/user/month. Pricing is quoted per-user and scales with team size.

Source
B2W Estimate: Is there a perpetual licence?

Current sales are subscription based. Existing perpetual customers have been migrated toward subscription, so treat a perpetual arrangement as something to negotiate rather than assume.

STACK Construction Technologies: Does STACK offer free options?

Yes, Takeoff & Estimate includes a free version, and Build & Operate includes a two-week free trial. Full STACK Platform offers a Build Your Price option for custom configurations.

Source
B2W Estimate: How does it compare with HeavyBid?

Both are production-rate estimators for heavy civil. B2W's argument is the shared resource database across estimating, field tracking, dispatch and maintenance; HeavyBid's is depth of bidding features and a large installed base in highway work.

STACK Construction Technologies: Can I get custom pricing from STACK?

Yes, STACK offers a Build Your Price option for the Full STACK Platform and Takeoff & Estimate to accommodate specific business requirements. Custom pricing requires direct consultation with their sales team.

Source
B2W Estimate: Does it work for building construction?

Poorly. It assumes self-performed work priced by crew output. Vertical builders bidding mostly subcontracted scopes should look elsewhere.

STACK Construction Technologies: How quickly can STACK be implemented?

STACK promises quick implementation measured in hours rather than weeks, though the exact timeframe depends on your configuration and team size.
