Summary of Differences

Edition	Advantages	Considerations
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.
OC4	All of the Enterprise features, plus… A collaborative, drag-and-drop study designer Ultra-capable forms engine supporting real-time edit checks, powerful skip logic, reason for change workflow, and auto-save Flexible form layout UI-optimized form items that include Likert scales, visual analog scales, images as selection choices, clickable image maps, large file uploads, and more
