Learn moreNot another tool. A complete ecosystem.
From server to email to client workflows — every layer is built to work together. Four things you will not get together anywhere else.
- One source of truth — one login, one database. An email becomes a task in one click, a task becomes an invoice.
- Your infrastructure — runs on your own server or on machines we operate. Either way, the data is yours.
- Open standards — JMAP, IMAP, CalDAV, WebDAV. Leave anytime, take everything.
- Managed end-to-end — fleet-managed servers, monitored 24/7, updated and self-healing — without you lifting a finger.

Teams that already switched.
We cancelled ten different subscriptions after rolling out FlowOne. The team adjusted within a week and nobody wants to go back.
An email becomes a task in one click, a task becomes an invoice. What used to get lost between three tools is now a single flow.
All of our data finally lives on our own server. On client audits that is an instant win — no third parties to explain.
The switch started with our email, and a few days later we were managing projects in the same system. The team adjusted quickly, and we juggle far fewer tools now.
The automation hub saves us hours every week: incoming orders turn into projects by themselves, with deadlines and owners.
Support is a different league too: instead of a ticket queue we talk to the people who build the system. Every request was answered within days.
Infrastructure you can depend on.
From a single server to full HA — live mirror, independent witness, off-site backups and long-term archival. Choose the architecture your business requires; takeover times are measured in live drills, not promised.
Your whole business. In your pocket.
The FlowOne iOS app brings your inbox, tasks, files and team chat everywhere you go — with push notifications and biometric login.
