EGroupware in depth: modules, synergies and real-world use cases

EGroupware is much more than calendar and webmail. Its real strength is the connection between CRM, email, projects, tasks, files, communication and e-invoicing.

What is EGroupware?

EGroupware is a browser-based open-source collaboration suite combining calendar, contacts/CRM, tasks, email, projects, files and other applications on one platform.

The real strength: no data silos

The value comes from connecting the modules. A contact can be connected to emails, appointments, tasks, projects and files, creating one shared business context.

Calendar + contacts

The calendar handles meetings, resources, invitations and reminders. Together with CRM data, appointments can be understood in customer and project context.

Email + CRM

The integrated mail client connects with other applications, keeping communication close to contacts, files and business processes.

Tasks + projects

Tasks capture ownership and status while project management brings together projects, subprojects, roles, budgets and operational work.

Time tracking + projects

Time tracking and project timers can be linked directly to project work, making hours meaningful for customers, projects and internal services.

Files + Collabora

The file manager provides central storage and permissions. Collabora Online enables collaborative document and spreadsheet editing in the browser.

Kanban + tickets + projects

Kanban visualises workflows for sales, projects, software development and services. Combined with tickets it creates status-driven processes.

Helpdesk + CRM + email

A complete support flow can be customer in CRM → email → ticket → assignment → Kanban → project/task → time tracking.

Customer → Email → Ticket → Kanban → Project/Task → Time → Invoice

Video conferencing and chat

Jitsi, BigBlueButton and other communication components bring meetings and collaboration closer to projects and tasks.

E-invoicing

The e-invoicing application supports XRechnung and ZUGFeRD according to EN 16931. Together with customer, project and time data it connects customer → project → work → invoice.

REST, CalDAV and CardDAV

Open interfaces enable integration with websites, ERP systems and automation. Contacts, calendars, tasks and email can be integrated.

Cloud or self-hosting

EGroupware offers cloud services as well as Community Edition and Enterprise Line installations, allowing organisations to balance operations, support and privacy.

Digital sovereignty

EGroupware positions itself around open source and development, hosting and support in Germany. This matters for organisations focused on data control.

EGroupware 26.2

The current release brings a responsive frontend, accessibility improvements and AI features including hybrid full-text/RAG search and AI tools for email and text fields.

Where the synergy really happens

A customer is not merely a CRM record: the same context can connect mail, appointments, projects, tasks, files, tickets, time and invoices.

Critical considerations

More integration also means a broader platform. Teams that only need mail and a calendar may prefer a specialist tool. Define modules, permissions, integrations and operating model first.

Who is it for?

It is particularly interesting for SMBs, service providers, associations, educational organisations and IT teams wanting CRM, projects, documents and communication together.

Verdict

EGroupware is strongest when you evaluate business processes rather than isolated apps. Customer + email + appointment + project + task + document + time + invoice can live in one connected system.
