Summary of Differences

EditionAdvantagesConsiderations
Community (Get started here.)

  • No set-up or subscription fees
  • Unlimited users, sites, and forms


  • Stand alone EDC
  • Basic forms
  • Not validated
  • Must be hosted on your own server
  • No dedicated support
Enterprise

  • Validated
  • Compliance support included
  • Cloud hosted for maximum security, reliability, and performance
  • Easy addition of ePRO, IxRS, supply management, and reporting modules
  • Robust integration with other common eClinical platforms (e.g. CTMS, biospecimen tracking)
  • Dedicated user support
Our software-as-a-service offering requires a low set-up fee and monthly subscription.

Note that the Community-related costs of self-hosting, validation, augmentation with ePRO and IxRS, and internal support can exceed the expense of Software-as-a-Service.
