The short version

  • Only Buildxact 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; Buildxact 15% discount applied only to annual billing
  • 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

Buildxact

  • 15% discount applied only to annual billing
  • Advanced AI add-ons require additional per-month fees

Answered from the vendors’ own pages

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.

Buildxact: What is the price difference between monthly and annual billing?

Annual plans include a 15% discount. For example, Foundation costs $199/month on monthly billing but $169/month ($2,030/year) on annual billing, saving $358 per year.

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.

Buildxact: How many users can access Buildxact?

Foundation, Pro, and Master plans include unlimited users. The free Go plan does not specify user limits.

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.

Buildxact: What add-on costs are available?

Additional AI tools cost $99/month for Blu Takeoff Assistant and $149/month for Blu Estimate Reviewer, available on Pro and Master plans.
