# Add more tokens, bots or seats with add-ons

**Available on:** Basic, Standard, Pro, Enterprise plans.

Add-ons raise one of your plan's limits without moving you to a bigger plan. They stack on top of whatever paid plan you're on, and you can change or remove them at any time.

> **Who can buy add-ons**
>
> **Who can do this:** [the team owner](https://chatthing.ai/docs/account/teams#what-each-role-can-do). Add-ons need an active paid plan, and you manage them on the **Billing** page, which only the owner can open.

## Available add-ons

| Add-on | What each unit adds | Monthly | Annually |
| --- | --- | --- | --- |
| **Message tokens add-on** | 5,000,000 message tokens a month | $25 a month | $250 a year |
| **Storage tokens add-on** | 5,000,000 storage tokens a month | $5 a month | $50 a year |
| **Extra bot** | One more bot for your team | $8 a month | $80 a year |
| **Extra data source** | One more data source per bot | $4 a month | $40 a year |
| **Extra team member** | One more seat on your team (organisation teams only) | $2 a month | $20 a year |
| **Custom Domain** | One custom domain for your team, used on any one bot | $25 a month | $250 a year |

Prices are in US dollars (USD) and exclude applicable taxes.

Token add-ons add [message tokens](https://chatthing.ai/docs/account/message-tokens) or [storage tokens](https://chatthing.ai/docs/account/storage-tokens) to your monthly allowance. A custom domain add-on lets you serve one bot from a [custom domain](https://chatthing.ai/docs/channels/website/custom-domain). The [pricing page](https://chatthing.ai/pricing) shows the same catalogue.

Some things are billed separately rather than as add-ons on this list:

- **Connected email account** ($10 a month or $120 a year per inbox) is added automatically when you connect an inbox for the [email inbox power-up](https://chatthing.ai/docs/power-ups/email-inbox). You don't buy it from the billing page.

### Token add-ons and the monthly reset

Token add-ons are added to your monthly allowance and reset along with it. If you need the extra tokens every month, keep the add-on active and it applies each cycle. See [when tokens reset](https://chatthing.ai/docs/account/message-tokens#when-tokens-reset).

## Steps

1. Go to [**Billing**](https://app.chatthing.ai/app/billing) and scroll to **Plan addons**.
2. Set the **Quantity** for each add-on you want. Setting it to 0 removes the add-on.
3. Select **Update addons**.
4. Check the summary. It shows each change and your **Overall monthly addon cost** before and after.
5. Select **Update addons** again to confirm.
6. You're taken to the billing portal, where you may need to confirm payment.

## How add-ons are billed

- Add-ons follow your plan's billing frequency: monthly prices if you pay monthly, yearly prices if you pay yearly.
- When you **add or increase** an add-on, you're charged straight away for the rest of your current billing period (prorated).
- On a yearly plan, the monthly cost of an add-on is prorated across the remaining months of the year.
- When you **remove or reduce** an add-on, the change shows on your subscription and your next invoice.

## Check it works

After your payment goes through, **Plan addons** on the billing page shows your new quantities. For token add-ons, the **Storage tokens** and **Message tokens** figures at the top of the billing page include the extra tokens.

## Troubleshooting

### Why can't I see the Extra team member add-on?

Personal teams always have exactly one member, so the add-on is hidden. [Convert your personal team to an organisation team](https://chatthing.ai/docs/account/teams#convert-a-personal-team-to-an-organisation) first.

### Why can't I reduce my custom domain add-on?

Each unit maps to one live custom domain. Remove the extra domains from your bots first, then reduce the quantity.

### Can I buy add-ons on the Free plan?

No. Add-ons are added to a paid subscription. [Upgrade to a paid plan](https://chatthing.ai/docs/account/billing#change-your-plan) first.
