The short version

  • Each has a real cost: Kahua no standard pricing tiers published; all pricing is custom and quote-based; Propeller Aero platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
  • They diverge on capability: Kahua covers Project management, Propeller Aero covers Photogrammetric processing.
  • Prices and features above were last checked on 1 September 2026.

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

Propeller Aero

  • Platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
  • The corrections network is free only while you hold a current platform licence, so cancelling the platform subscription reintroduces a 1,000 dollar per year per group hardware cost that many buyers do not model
  • AeroPoints are a hardware purchase at 1,000 dollars each and most sites need several, so the true entry cost includes several thousand dollars of equipment on top of a subscription
  • It measures rather than designs, so a contractor still needs Civil 3D, Trimble Business Center or an equivalent to produce and revise the design surfaces the measurement is compared against
  • Accuracy depends on flight planning, ground control placement and weather, and a poorly flown survey produces a confident wrong volume, so an organisation still needs someone who understands survey error rather than only a drone pilot

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
Propeller Aero: How much does Propeller cost?

The platform is quoted and not published. AeroPoints are 1,000 US dollars each, with the corrections network included for twelve months and thereafter free while a platform licence is current, otherwise 1,000 dollars a year per group.

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
Propeller Aero: Do I need AeroPoints?

No, you can use conventional surveyed ground control, but the AeroPoints workflow is the main reason contractors choose Propeller over generic photogrammetry.

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
Propeller Aero: Is it survey grade?

Propeller states centimetre-level accuracy with correct ground control. Whether that satisfies a contract depends on your specification and on how the survey was flown, not on the software alone.

Propeller Aero: Who owns the data?

You retain your survey data and can export surfaces and point clouds, but check the export formats and retention terms in your contract before closeout, because bulk historical export is not a self-service one-click operation.
