# Billing

> Manage your plan, payment details, and invoices in Chatarmin CX.

Use Billing to manage the administrative details of your Chatarmin CX subscription.

## What you can manage

* Review your plan, subscription status, seats, and renewal date
* Update your payment method, company details, and tax identifier
* Open or download past invoices

Use **Manage** or **Edit** to open the billing portal.

## AI usage

To check credits used by your AI Agents, [open AI usage](https://armin.cx/app/_/settings/billing/usage). For typical credit use by support job, see [AI credits](/ai-agents/ai-credits).

## When agents pause

AI Agents can pause when payment has failed, your subscription is past due, or there is no active subscription. Your Inbox, channels, and the rest of Chatarmin CX stay available. Update your payment details in Billing to resume agents.
