The short version

  • Each has a real cost: Kojo benefits depend on distributors providing electronic catalogues and pricing, and a contractor whose main supplier will not participate is left keying quotes by hand.; 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: Kojo covers Field material requests, Propeller Aero covers Photogrammetric processing.
  • 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.

Kojo

  • An electrical or mechanical contractor where materials are close to half of job cost and buying happens dailynot Propeller Aero
  • A trade contractor that cannot see committed material cost against a job until the invoice arrivesnot Propeller Aero
  • A contractor consolidating purchasing across branches to negotiate better distributor pricingnot Propeller Aero
  • A subcontractor tracking warehouse stock and job transfers that currently live in a spreadsheetnot Propeller Aero

Propeller Aero

  • A quarry that reconciles stockpile inventory monthly for its accounts and wants the volume evidence to survive an auditnot Kojo
  • An earthworks contractor claiming progress payments on cubic metres moved who needs an independent measurement the client will acceptnot Kojo
  • A civil site checking whether a subgrade is within tolerance of the design before the surfacing crew arrivesnot Kojo
  • A mine that wants weekly volume reporting without a survey crew on the ground every weeknot Kojo

Where each one falls short

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

Kojo

  • Benefits depend on distributors providing electronic catalogues and pricing, and a contractor whose main supplier will not participate is left keying quotes by hand.
  • It serves speciality trade contractors; general contractors procure subcontracts rather than materials and get almost nothing from it.
  • Enterprise resource planning integration quality varies by system and version, so confirm the depth for your exact configuration rather than accepting the logo on the website.
  • Field adoption is the whole game, and foremen who lose signal in a plant room or basement revert to phoning the office within days unless offline capture genuinely works.
  • It changes purchasing process as well as software, so contractors whose buying authority is informal have to formalise who can commit money before the system produces clean data.

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

Kojo: Is this for general contractors?

No. It is built for speciality trade contractors buying materials. General contractors procure subcontracts and would get little from it.

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.

Kojo: What if our suppliers will not connect?

You lose most of the quoting benefit and keep only the internal workflow. Check distributor participation before purchase, because it determines the return.

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.

Kojo: Does it work without signal on site?

Field requests are designed for site use, and offline behaviour should be tested with your own crews in your worst locations, because that is where adoption is won or lost.

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.
