About GroupOffice

GroupOffice is an open-source groupware and enterprise CRM platform. It enables teams to collaborate through shared projects, calendars, files, and email. The software can be self-hosted for full control or used as a cloud-based service.

GroupOffice is an open-source enterprise CRM and groupware suite designed for team collaboration and business management. It offers both a self-hosted version for complete data control and a cloud-hosted option. Core functionalities include project management, shared calendars, file sharing, and an integrated email client. The platform also features a robust CRM for managing contacts, support tickets, and newsletter campaigns. For financial tasks, it supports invoicing and online payments. GroupOffice integrates with document editing tools like OnlyOffice and Collabora Online. While it provides a free community edition and a 30-day trial for its professional version, there are no dedicated native mobile or desktop applications; instead, it relies on syncing with existing device apps via open protocols like CalDAV and CardDAV.
