The short version

  • Each has a real cost: Assignar it is built for contractors who own crews and plant, so a general contractor coordinating subcontractors gets little from it beyond its own self-perform scopes.; 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
  • They diverge on capability: Assignar covers Crew and equipment scheduling, B2W Estimate covers Production-rate estimating.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Assignar

  • A concrete or earthworks subcontractor replacing paper dockets that arrive three days latenot B2W Estimate
  • A contractor that must prove operator competency and induction status on regulated sitesnot B2W Estimate
  • A self-perform contractor comparing actual crew hours against estimated production ratesnot B2W Estimate

B2W Estimate

  • A grading contractor bids a 40 million dollar DOT job and needs to test three crew configurations against the same quantities before the bid deadlinenot Assignar
  • A utility contractor wants the production rates used in the winning bid pushed into field logging so the superintendent is measured against the estimatenot Assignar
  • An estimating department with four estimators needs several people working on separate sections of one bid without merging spreadsheets by handnot Assignar
  • A contractor moving off HeavyBid wants a resource database it can reuse across estimating, dispatch and fleet maintenancenot Assignar

Where each one falls short

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

Assignar

  • It is built for contractors who own crews and plant, so a general contractor coordinating subcontractors gets little from it beyond its own self-perform scopes.
  • It is not an accounting or payroll system, so the value depends on a clean integration to your finance system and on someone owning the reconciliation when hours disagree.
  • Australian origins show in terminology and compliance defaults, and North American users spend setup time translating concepts such as tickets and inductions into local equivalents.
  • Offline capture works, but photo-heavy forms on poor connections remain the weak point and should be tested on your worst site before a full rollout.
  • Supervisors have to maintain the schedule for the reporting to mean anything, and dispatchers used to a whiteboard resist that for months unless the change is enforced.

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

Answered from the vendors’ own pages

Assignar: Is this for general contractors or subcontractors?

Speciality and self-perform contractors. The unit of work is a crew and a machine on a shift, which is not how a general contractor coordinates trades.

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.

Assignar: Does the mobile app work without signal?

Yes, entries are captured offline and synchronised later. Test it with photos attached on your worst site, because that is where sync problems appear.

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.

Assignar: Does it handle payroll?

No. It captures hours and quantities and passes them to your payroll or enterprise resource planning system.

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.

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.
