The short version

  • Each has a real cost: ALICE Technologies the output is only as good as the recipes, and building accurate recipes is specialist modelling work most contractors cannot staff, so engagements depend on ALICE or a consultant doing it, which turns software into a services contract.; Trimble Pay the Flashtract name is being retired in favour of Trimble Pay, so existing documentation, comparison articles and integration listings are split across two names and buyers should confirm which contract entity and which support channel applies
  • They diverge on capability: ALICE Technologies covers Generative scheduling, Trimble Pay covers Automated pay applications.
  • 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.

ALICE Technologies

  • A data centre programme where six months of earlier energisation is worth more than the entire construction management budget, and the owner wants evidence that a proposed sequence change actually delivers itnot Trimble Pay
  • A contractor facing liquidated damages that must decide between a second shift, a second crane and resequencing, and needs the cost and duration consequence of each before committingnot Trimble Pay
  • A bid team wanting to submit a shorter programme than competitors while proving to the client that the resource profile is achievable rather than optimisticnot Trimble Pay
  • A delay claim where the contractor must demonstrate to a client or adjudicator what the schedule would have looked like without a specific disruptionnot Trimble Pay

Trimble Pay

  • A general contractor whose accounts payable team rejects a third of subcontractor billings each month for arithmetic or form errorsnot ALICE Technologies
  • A contractor working across several states that needs the right statutory waiver language selected automatically rather than from a shared template foldernot ALICE Technologies
  • A company that has been quoted Oracle Textura and wants to compare the total cost when the fee falls on the contractor rather than on the tradesnot ALICE Technologies
  • A contractor that needs the unconditional waiver to be released only after funds clear, so it is not holding a waiver that a court would treat as ineffectivenot ALICE Technologies

Where each one falls short

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

ALICE Technologies

  • The output is only as good as the recipes, and building accurate recipes is specialist modelling work most contractors cannot staff, so engagements depend on ALICE or a consultant doing it, which turns software into a services contract.
  • Pricing is quoted per project or programme with no published rates, so the tool is effectively unavailable to anyone who cannot justify a bespoke enterprise negotiation.
  • It only pays back on projects where float has a high monetary value; on a mid-size commercial building the modelling effort exceeds the schedule saving, which is why the customer list skews to data centres, energy and heavy civils.
  • A generated schedule still has to be accepted by superintendents and subcontractors who did not build it, and adoption failures are usually social rather than technical: the field runs the plan it believes in.
  • The 2026 McKinsey alliance pushes distribution towards consulting-led engagements, which raises the effective cost of entry and makes the direct-purchase path less certain for a contractor that just wants a licence.

Trimble Pay

  • The Flashtract name is being retired in favour of Trimble Pay, so existing documentation, comparison articles and integration listings are split across two names and buyers should confirm which contract entity and which support channel applies
  • Pricing is not published, and because it is bought by the general contractor rather than charged to subcontractors, the whole cost lands in one budget line rather than being distributed across the supply chain
  • It is billing and compliance only, so a contractor still needs a project management system for drawings and RFIs and a construction ERP for the general ledger, and the value depends heavily on the quality of those two integrations
  • Lien waiver correctness is a legal question, and the system generates forms rather than giving advice, so a contractor operating in an unusual jurisdiction still needs counsel to confirm the templates match current statute
  • Under Trimble the product now sits alongside other Trimble construction financial assets, and buyers signing multi-year terms should ask directly how it is positioned against Viewpoint and the rest of the Trimble construction portfolio

Answered from the vendors’ own pages

ALICE Technologies: What does ALICE actually produce?

A set of alternative construction sequences generated from your constraints, scored on duration, cost and resource use, so you can choose rather than accept one plan.

Trimble Pay: Is Flashtract still sold under that name?

No. Trimble acquired Flashtract and now sells it as Trimble Pay. The flashtract.com content redirects into the Trimble product pages.

ALICE Technologies: Does it replace Primavera P6?

No. It imports from and exports to P6. P6 remains the contractual schedule of record on most projects.

Trimble Pay: Do subcontractors pay to use it?

No. The general contractor buys it. This is the main commercial difference from Oracle Textura, where subcontractors are billed a percentage of their contract value per project.

ALICE Technologies: Is the company still operating?

Yes. ALICE is active as of 2026 and announced an alliance with McKinsey in April 2026 to deliver AI scheduling to McKinsey clients.

Trimble Pay: Does it replace my accounting system?

No. It generates and approves the billing and the waivers, then posts to your construction ERP. You still need the ledger.

ALICE Technologies: How much does it cost?

Not published. It is quoted per project or programme and typically includes modelling and onboarding services.

Trimble Pay: Does it handle lower-tier subcontractors?

Yes, it tracks sub-tier amounts and sworn statements against the prime commitment, which is the usual source of surprise lien exposure.

ALICE Technologies: What size project justifies it?

Projects where a week of schedule has a large monetary value: data centres, energy, industrial and major infrastructure. It is hard to justify on standard commercial building work.
