The short version

  • 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; Trunk Tools nothing about pricing is published, and because it is quoted by project rather than by seat, the cost of standardising it across a portfolio of jobs is hard to model before a sales process
  • They diverge on capability: B2W Estimate covers Production-rate estimating, Trunk Tools covers Question answering with citations.
  • 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

Trunk Tools

  • Nothing about pricing is published, and because it is quoted by project rather than by seat, the cost of standardising it across a portfolio of jobs is hard to model before a sales process
  • Answer quality is bounded entirely by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones
  • It is an overlay on Procore or Autodesk rather than a system of record, so a contractor is now paying two vendors for the same document set and depends on the integration continuing to be maintained
  • The company is young and the product category is new, so there is little independent long-run evidence on accuracy, and a contractor putting field decisions on it should build its own verification sampling rather than trust vendor claims
  • Answers with citations do not carry contractual weight; an RFI response or a specification still governs, so the tool reduces search time without reducing the contractual review burden

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.

Trunk Tools: Does it replace Procore?

No. It reads from Procore or Autodesk Construction Cloud and adds retrieval and review on top. You still pay for the document platform.

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.

Trunk Tools: What does it cost?

Trunk Tools does not publish pricing. Expect a quote scoped by project, users and which modules you take.

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.

Trunk Tools: Can it be wrong?

Yes. It cites its source, which lets you check, but if the document set contains superseded drawings it will answer from them. Document control discipline is a prerequisite, not an optional extra.

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.

Trunk Tools: Can field staff use it without the app?

Yes. TrunkText answers questions by text message, which is the main reason foremen adopt it.
