churn_signals lists canceled and unpaid subscriptions and past-due accounts, joined to the CRM so you know who owns them. revenue_summary gives MRR and ARR by subscription status, so renewal conversations start from what customers actually pay.
The CRM can show a customer as healthy months after they canceled in billing. Agents that only read the CRM will tell you everyone is fine.
Two commands, no credentials. Then connect HubSpot when you are ready.
