CitizenOne is a case management system designed for social services organizations to manage citizen cases, track progress, and securely store documentation. It combines tools for documentation, communication, and operational management within a single platform. The system includes features such as daily journaling for case documentation, plans and goals management to monitor citizen development, and a medication journal that retrieves medication overviews from the Danish FMK system. Document management tools allow for centralized storage and organization of citizen files. A built-in chat function enables staff to communicate about case data without leaving the platform. Additional tools include employee onboarding, shift scheduling, and access to an app store offering features such as Secure Mail and ConsentPlus. CitizenOne complies with EU GDPR regulations and operates on ISO 27001-certified servers located within the European Union. It is designed to support multiple operational needs in one system, reducing the need for separate tools for case management, communication, and documentation.
