# Plans and billing

> Understand SiteGPT plans and manage your subscription.

SiteGPT has four plans: **Starter**, **Growth**, **Scale**, and
**Enterprise**. Current prices, message allowances, and feature comparisons
live on the [pricing page](https://sitegpt.ai/pricing); this page explains
how the quotas work and how to manage your subscription.

## What the plans meter

| Quota                  | What it means                                                                                                                                                            |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Messages per month** | Chatbot answers across your account, tracked separately for GPT-4.1 Mini and GPT-4.1 (see the **GPT Model** setting in [model settings](/docs/customize/model-and-behavior)). |
| **Chatbots**           | How many chatbots the account can have: 1 on Starter, 2 on Growth, 3 on Scale, custom on Enterprise.                                                                     |
| **Pages**              | Training content, where one page is 2,500 cleaned characters. See [pages quota](/docs/features/pages-quota).                                                                  |
| **Team members**       | Unique invited emails across your chatbots: 1 / 4 / 10 / custom. See [members](/docs/features/members).                                                                       |

Track all of them on your **Usage** page.

## Manage your subscription

Open **Billing** in the top navigation to:

* **Upgrade or change plans.** Checkout and payment are handled by Paddle,
  our payments partner; cards and common local methods are supported, and
  annual billing is cheaper than monthly.
* **See invoices and receipts.** Paddle emails receipts for every charge.
* **Add-ons.** Optional extras (like removing the "Powered by SiteGPT"
  branding and message packs) are listed on the Billing page with current
  prices.
* **Cancel.** Cancellation stops renewal at the end of the paid period; your
  chatbots keep working until then.

<Note>
  The Billing page also shows your account **API key** if your plan includes
  API access. That key is for the legacy v0 API; new integrations should use
  scoped tokens from the [Agents page](/docs/developers/api-tokens-and-mcp).
</Note>

## Common billing questions

<AccordionGroup>
  <Accordion title="What happens when I hit my message quota?">
    The chatbot stops answering until the quota resets at the next billing
    cycle, you upgrade, or you add a message pack from the Billing page.
    Watch the **Usage** page as you approach the line.
  </Accordion>

  <Accordion title="What happens if a payment fails?">
    Paddle retries failed payments and emails you. Sort out the payment
    method promptly to avoid interruption; your data is not deleted because
    of a failed payment.
  </Accordion>

  <Accordion title="Do unused messages roll over?">
    No. Quotas reset each billing cycle.
  </Accordion>

  <Accordion title="I need an invoice with my company details">
    Receipts come from Paddle and can carry your business details. For
    anything unusual, contact [support@sitegpt.ai](mailto:support@sitegpt.ai).
