The short version

  • Each has a real cost: Castor EDC nothing is published: pricing is quoted only after a scoping call and protocol review, so budgeting a grant application means asking for a quote months before the study is funded and hoping the scope holds.; Florence eBinders pricing is set against how much your sponsors are expected to reimburse rather than a rate card, so two similar sites can pay materially different amounts and neither has a public benchmark to negotiate against.
  • They diverge on capability: Castor EDC covers Browser-based study build, Florence eBinders covers Electronic investigator site file.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Castor EDC

  • Nothing is published: pricing is quoted only after a scoping call and protocol review, so budgeting a grant application means asking for a quote months before the study is funded and hoping the scope holds.
  • Price scales on protocol complexity rather than a simple unit, so two studies with the same participant count can be quoted very differently and there is no public benchmark to argue against.
  • Modules such as eConsent, ePRO and randomisation are quoted on top of the base platform, so the headline EDC figure is rarely the number that appears on the final proposal.
  • It is deliberately lighter than the full sponsor suites, so a study that grows into a global registrational programme needing integrated CTMS, safety, IRT and full trial supply management will need additional systems and the interfaces between them.
  • Regulatory responsibility does not transfer with the software: the platform supports Part 11 compliant workflows, but system validation for your intended use, SOPs and audit readiness remain your obligation and your cost, which sponsors new to EDC consistently underestimate.

Florence eBinders

  • Pricing is set against how much your sponsors are expected to reimburse rather than a rate card, so two similar sites can pay materially different amounts and neither has a public benchmark to negotiate against.
  • It is site-side only: it does not do electronic data capture, study budgeting or full trial management, so a research office still runs a CTMS and an EDC alongside it and pays for the interfaces between them.
  • The benefit case depends on sponsors and monitors actually using remote access; if your sponsor mix insists on on-site source data verification, you have digitised the binder without removing the visits that made it expensive.
  • Migrating years of existing paper and scanned regulatory documents into structured, indexed binders is a substantial one-off project that sites routinely underestimate and that is scoped and charged separately.
  • Adoption is heavily United States centred, so a European or Asian site will find fewer sponsors familiar with the platform and less mature alignment with local regulatory expectations than a domestic site enjoys.

Answered from the vendors’ own pages

Castor EDC: Is there a free academic version?

No published free tier. There are academic, non-profit and grant-funded pricing paths, but each is quoted rather than self-service.

Florence eBinders: Is this an EDC system?

No. It manages the site regulatory binder and source documents. Trial data capture is a separate system such as Medidata, Castor or REDCap.

Castor EDC: Is it 21 CFR Part 11 compliant?

It supports Part 11 compliant workflows with audit trails and electronic signatures. Validating the system for your specific use remains your responsibility.

Florence eBinders: Who normally pays for it?

The site buys it, but sites commonly recover the cost through per-study sponsor budgets, and Florence prices with that expected reimbursement in mind.

Castor EDC: Do I need a programmer to build a study?

No. Case report forms are configured in the browser, which is the main reason academic groups adopt it.

Florence eBinders: Does it support 21 CFR Part 11?

Yes, with electronic signatures, audit trails and access controls. Validation for your intended use is still your responsibility.

Castor EDC: How long does a quote take?

Castor states a full pricing proposal within five business days of sharing the protocol.

Florence eBinders: Can sponsors see our documents?

Only what you grant through SiteLink. Documents stay under site control rather than in a sponsor-owned repository.
