How do I cancel?

Open Company admin, Plan, then Your plan, and press Manage subscription. It opens Stripe's own page for your subscription, which is where you cancel.
Your jobs, claims, variations, retention, statutory dates and every document you uploaded stay exactly where they are: readable, writable and exportable. Every job you started while subscribed keeps every tab.
The end of the plan changes only one thing: a NEW job. You can quote a job you open after that. Every other tab on it says it opens when you subscribe.
Subscribe again from Your plan, and it covers every job straight away. You set up nothing twice.

Worth knowing

This matters most for retention. A retention claim can fall due a year after the crew leaves. You keep the record you need to chase it, subscribed or not.
