The short version

  • Only Buildxact has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildxact 15% discount applied only to annual billing; Oracle Primavera Unifier nothing works until it is configured, so the first useful business process is months away and usually costs more in partner services than the first year of licences; organisations that budget for software and not for implementation stall.

Oracle Primavera Unifier

  • A university estates office that needs one cost sheet spanning design, construction and handover, with the asset data surviving into facilities management rather than being rekeyednot Buildxact

  • An owner already committed to Primavera P6 and Aconex that wants cost and contract control in the same estate rather than adding a separate construction ERPnot Buildxact

Where each one falls short

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

Buildxact

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

Oracle Primavera Unifier

  • Nothing works until it is configured, so the first useful business process is months away and usually costs more in partner services than the first year of licences; organisations that budget for software and not for implementation stall.
  • Modules are licensed separately, so an organisation that starts with Project Controls and later wants facilities and asset management faces a second negotiation at whatever list price applies then, not the rate it originally agreed.
  • Per-user licensing punishes occasional participants: a project sponsor who approves four invoices a year consumes the same licence as a full-time cost controller unless workflows are redesigned to keep them out of the system.
  • Oracle's term licence pricing is a percentage of the perpetual list rising with duration, which means a one-year term looks affordable and then the renewal maths pushes buyers into long commitments they cannot easily exit.
  • The interface is dated relative to modern construction software and field users resist it, so many implementations end up with Unifier as an office system and a separate mobile tool for site, which reintroduces the data gap it was bought to close.

Answered from the vendors’ own pages

Buildxact: Does Buildxact offer a free tier?

Yes, Buildxact's Go plan is free and includes 5 complimentary credits for AI Estimating and Professional Proposals, plus access to Home Depot Material Ordering.

Source
Oracle Primavera Unifier: Does Oracle publish Unifier pricing?

No. Unifier is quoted per user and per module through Oracle or a partner. Global price lists exist for some Primavera products but Unifier is negotiated.

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.

Source
Oracle Primavera Unifier: Is Unifier the same as Primavera P6?

No. P6 is scheduling. Unifier is cost, contract, change and asset management. Owners commonly run both and integrate them.

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
Oracle Primavera Unifier: Can we still buy a perpetual licence?

Yes, perpetual licensing remains available alongside term licences, and Oracle prices terms as a percentage of the perpetual list. Check which your quote is based on.

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.

Source
Oracle Primavera Unifier: Who owns the data at project closeout?

The customer owns its data. Export is possible through the API and reporting layer, but configured business process records do not move cleanly into another system, so plan closeout extraction before you need it.

Oracle Primavera Unifier: Is it suitable for a general contractor?

Rarely. Unifier is built around the owner's funding and contract position. Contractors are usually better served by Procore or Autodesk Construction Cloud.
