# Billing and subscription

The subscription plan can be paid by card through Stripe per machine, or under a contract with Spiroq. In settings you therefore see exactly one of these tabs, never both at once. More about the subscription is on [Plans](/en/guides/navody/getting-started-and-installation/tarify.md).

## Billing & Plans

Active when paying through Stripe. Here you find the overview and invoices, and the **Manage in Stripe** link (invoices, card, change of period). Subscription changes on machines, including a bulk change, are on the [machine list](/en/hub-screens/hub/seznam.md) on the **Subscription overview** tab. You can also change one machine's plan in the [machine detail](/en/hub-screens/hub/seznam/zahlavi.md).

A bulk change requires at least one subscription already paid in Stripe. Without it, Stripe does not know who to issue the invoice to.

## Subscription

Active under a contract with Spiroq. You do not pay the plan per machine — it is a single operator plan. You arrange a plan change with Spiroq, not with a button on the machine.
