The short version

  • Each has a real cost: Billd the contractor carries the fee rather than the supplier, so unless the cost is bid into the job or offset by a negotiated supplier cash discount, financed material is simply more expensive material.; 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: Billd covers Material financing, 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.

Billd

  • The contractor carries the fee rather than the supplier, so unless the cost is bid into the job or offset by a negotiated supplier cash discount, financed material is simply more expensive material.
  • No rate card is published, so the effective annualised cost is only visible after underwriting and cannot be compared against a bank line or a card facility before you apply.
  • A 120 day term assumes the general contractor pays roughly on time; if the GC drags past that, the subcontractor owes Billd on schedule regardless of whether it has been paid.
  • This is credit, not construction software, so it adds a debt obligation and a covenant relationship to a business that a surety and a bonding agent will look at when setting bonding capacity.
  • Coverage is US commercial construction, so contractors outside that market or working residential get little from it, and eligibility depends on project type and the creditworthiness of the paying party.

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

Billd: Who pays Billd's fee, the contractor or the supplier?

The contractor. The supplier is paid upfront in full and carries no credit risk.

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.

Billd: Does Billd publish rates?

No. Cost depends on term, product and underwriting outcome and is disclosed in the offer.

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.

Billd: What happens if my general contractor pays late?

You still owe Billd on the agreed schedule. The 120 day term is designed to cover a normal pay cycle, not a dispute.

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.

Billd: Does using Billd affect bonding capacity?

It is a debt facility, so a surety will consider it. Discuss it with your bonding agent before drawing heavily.

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.
