Anyone who signs in to Centrion with their own login or access key — employees, security officers, store operatives and admins. Visitors and delivery drivers signed in at the gate don't count, however many you have.

Everyone who already has a key keeps working. New keys can't be issued until you revoke ones that are no longer needed or move up a plan — the Keys page shows how many you've used, and we'll get in touch before you get close. When you upgrade, you only pay the difference from that point.

Monthly plans are paid by card through Stripe and can be cancelled any time; the service runs to the end of the month you've paid for. Annual plans are paid upfront with one month free, and can be cancelled within 30 days for a refund of the unused months. Enterprise customers can pay by invoice. Full details are in our terms.
