What an Enterprise OS is

Not just another app.
An operating system for your company.

Traditional companies juggle a dozen tools that never talk to each other. Data is scattered, time is lost on copy-paste, and no one has full control.

Sentrix works like an operating system: one database, one permission layer, one workflow engine — and the modules are apps that know each other. Mail knows about the case, the case about the invoice, the invoice about the warehouse.

FAQ

Frequently asked questions

Sentrix is an operating system for your company that brings every process together in one place. Documents, cases, invoices, business travel, transport, CRM, mail, calendar and workflow — with no switching between apps.

Yes. The architecture is modular — you start with selected modules (e.g. DMS + Mail) and add more as you need them. There is no obligation to deploy everything at once.

The system is based on RBAC (Role-Based Access Control) with granularity down to a single document (ACL). Roles, groups, access policies and a full audit trail.

Yes. REST API, webhooks, integration with Microsoft 365, Google Workspace, IMAP/SMTP, LDAP/AD and Keycloak. On the roadmap: KSeF, e-Delivery, ePUAP 2.0.

Sentrix is designed as on-premise first — your data stays on your own server. We also offer a private cloud version.

KSeF 2.0 integration is in phase 1 of the roadmap. e-Delivery and ePUAP 2.0 are planned for phase 2.
