# Upgrade and Manage

> Where to change plans, how billing works, and how a plan change reaches the plugin.

Plans are chosen and managed at **[trynito.ai](https://trynito.ai)**, not from inside a chat. The plugin reads your plan; it does not sell or change it. That keeps payment out of your harness session and in the billing surface where it belongs.

## Upgrading

Open **Billing** at [trynito.ai](https://trynito.ai) and pick a plan. You can move up at any time: Free to Plus, Plus to Advanced, Advanced to Max. Each plan includes everything below it, so upgrading only adds. For what each one unlocks, see [What Paid Unlocks](/plans/what-paid-unlocks).

<Note>
  Prices are set live and can vary by region and billing period. Confirm the current price for your account before subscribing.
</Note>

## Payment Options

Billing supports standard card checkout, and crypto-wallet payment is available on eligible plans. What you see at checkout depends on your account and region.

## Managing an Existing Subscription

From **Billing** you can:

* Change or cancel your plan.
* Switch between monthly and annual billing.
* View invoices and billing history.

## How a Change Reaches the Plugin

Your plan is read live, so a change takes effect without reinstalling anything. After upgrading, confirm the new plan on your [status card](/plans/checking-usage) with `status` in a chat, or `nito agent status` from the terminal.

<Note>
  If a newly unlocked feature like [Fusion](/commands/fusion) or a [full session](/commands/session) still reports as unavailable right after upgrading, check `status` to confirm the new plan has landed, then run the command again.
