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.; eSUB limited to commercial subcontractors; not suitable for general contractors or non-construction industries
  • They diverge on capability: ALICE Technologies covers Generative scheduling, eSUB covers Mobile task management.
  • 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 eSUB

  • 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 eSUB
  • A delay claim where the contractor must demonstrate to a client or adjudicator what the schedule would have looked like without a specific disruptionnot eSUB

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.

eSUB

  • Limited to commercial subcontractors; not suitable for general contractors or non-construction industries
  • Custom pricing with no transparent public pricing makes budget planning difficult for prospective customers
  • Narrow candidate list with only one direct competitor (Procore) in the space
  • May have smaller feature set compared to enterprise construction platforms

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.

eSUB: What is eSUB designed for and who is the primary user?

eSUB is a mobile-first construction management platform built exclusively for commercial subcontractors. It connects the field to the office through mobile apps and web interfaces for creating, tracking, and managing documents and daily activities.

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

eSUB: What key features does eSUB Cloud include?

eSUB includes submittals, change orders, RFIs, daily reports, mobile app functionality, email integration, field notes, time cards, project management, document management, time tracking, and job costing capabilities.

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

eSUB: Does eSUB offer a free trial?

Yes. eSUB offers a 14-day free trial as well as customized demos. The demo includes a 45-minute guided walkthrough in a staged demo project.

eSUB Cloud pricing depends on user count and modules required; quotes are provided on a customized basis. No implementation fees apply for standard scopes, and no per-job charges are assessed. Updates are included in the subscription.

Source
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.

eSUB: What platforms does eSUB support?

eSUB offers mobile apps for both iOS and Android, as well as a web interface. The platform is designed mobile-first with field-focused functionality.
