Ascensio System SIA

Ascensio System SIA develops ONLYOFFICE, an office and collaboration suite for small and medium-sized businesses. It brings document editing, project management and customer relationship tools into one place, so staff avoid switching between separate applications.

The suite can be used as a hosted workspace, connected to another platform, or installed as desktop and mobile apps.

• DocSpace — secure rooms where people are invited to view, edit and collaborate on files.
• Integrations — more than 40 connectors, including Nextcloud, Moodle, Odoo and WordPress, plus options to embed the editors in other services.
