We’ve been using Onoff Business for over 4 years. Beyond boosting our teams’ productivity, saving them roughly 5 hours per week, Onoff Business has helped us stay true to our company values, especially inclusive hiring.

Onoff Business is a cloud-based business phone system that gives every employee a dedicated business number, accessible directly from their smartphone — with no additional SIM card or hardware to install.
Each employee downloads the app and activates their business number on their existing phone. They can keep their work and personal calls separate on a single device, while the business retains centralised management and control.
From solo entrepreneurs to sales teams of 200 people, Onoff Business adapts to the size of your organisation, with plans designed to support you at every stage of growth.
Les tarifs démarrent à partir de 19€/utilisateur/mois, avec des paliers adaptés selon vos besoins (équipe solo, équipe commerciale, ou organisation avec automatisation avancée).
Plans start from €19 per user per month, with options to suit your needs — from solo teams and sales teams to organisations requiring advanced automation.
No hardware or complex technical setup is required. Your teams can be up and running in just a few minutes.
