The short version

  • Each has a real cost: Kahua no standard pricing tiers published; all pricing is custom and quote-based; 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and usually costs more in partner services than the first year of licences; organisations that budget for software and not for implementation stall.
  • They diverge on capability: Kahua covers Project management, Oracle Primavera Unifier covers uDesigner configuration.
  • Prices and features above were last checked on 1 September 2026.

Oracle Primavera Unifier

  • A state transport agency tracking dozens of concurrent projects funded from separate multi-year appropriations, where the audit trail on which fund paid for which change order matters more than scheduling detailnot Kahua
  • 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 Kahua
  • A utility that must produce regulator-facing cash flow and capitalisation reports directly from the project controls system rather than from a spreadsheet reconciled once a quarternot Kahua
  • 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 Kahua

Where each one falls short

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

Kahua

  • No standard pricing tiers published; all pricing is custom and quote-based
  • Pricing varies by organization type, program or construction scale, selected package, and deployment environment
  • Implementation costs for data migration, integrations, training, and configuration scoped separately and included in quote

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and usually costs more in partner services than the first year of licences; organisations that budget for software and not for implementation stall.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

Kahua: How much does Kahua cost?

Kahua does not publish standard pricing. Costs vary by organization type (Owners/Program Managers, General Contractors, Specialty Contractors), program scale, selected package, deployment environment, and implementation requirements. Customers must request pricing quotes.

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.

Kahua: What package options does Kahua offer?

Kahua offers three main package categories: Owners and Program Managers, General Contractors, and Specialty Contractors. Additional specialty apps and suites including capital planning, analytics, asset management, and safety can extend the base solution.

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.

Kahua: Are implementation and integration costs included in Kahua pricing?

Implementation details including data migration, integrations, training, and configuration are scoped based on requirements and clearly identified in the custom quote provided.

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.

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.
