The short version

  • Only Elicit has a free tier, so it costs nothing to try first.
  • Each has a real cost: Elicit pro and Scale plans available at different monthly prices; annual billing options not specified; Greenphire the standalone greenphire.com site now redirects to Suvoda and the brands have been integrated, so buyers are contracting with a randomisation and supply vendor and should expect cross selling rather than an independent payments specialist.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Elicit

  • Pro and Scale plans available at different monthly prices; annual billing options not specified
  • Enterprise plan pricing not disclosed; requires contacting vendor

Greenphire

  • The standalone greenphire.com site now redirects to Suvoda and the brands have been integrated, so buyers are contracting with a randomisation and supply vendor and should expect cross selling rather than an independent payments specialist.
  • Nothing is published on price, and the typical shape of a platform fee plus per participant and per transaction charges means the cost of a trial is not knowable until enrolment is known.
  • Payment method availability varies sharply by country, so a global protocol may end up with card payments in some regions and slow manual processes in others, which undermines the retention argument that justified the purchase.
  • Sites bear the administrative work of enrolling participants and triggering payments but are not the buyer, so adoption depends on the sponsor mandating it and site resistance is a real implementation risk.
  • Participant payments create tax reporting obligations that differ per jurisdiction, and the tooling helps but does not remove sponsor liability, so legal and finance review is required in every country the trial runs in.
