**Usage and billing**

# Add-ons

Add-ons let you raise the limits on your current plan without upgrading to a higher tier. Need more messages this month, one extra bot, or another team seat? Add the matching add-on and only pay for what you need. Add-ons stack on top of whatever plan you're on, and you can change or remove them at any time.

You manage all of your add-ons from your [billing page](https://staging-app.chatthing.ai/app/billing).

ℹ️

Only owners and admins can change add-ons

Add-ons are billed against your subscription, so only team owners and admins can add, change, or remove them.

## Token boosts

If you're running low on tokens before your monthly reset, token boosts top up your allowance straight away instead of waiting for the 1st of the month or moving to a bigger plan.

### Message token boost

Adds **5,000,000 [message tokens](https://chatthing.ai/docs/what-are-message-tokens)** to your monthly allowance per unit. Buy more than one unit to add multiples of 5,000,000. Use this when your bots are handling more conversations than your plan includes.

- **$25 / month** per 5,000,000 message tokens
- **$250 / year** per 5,000,000 message tokens

### Storage token boost

Adds **5,000,000 [storage tokens](https://chatthing.ai/docs/what-are-storage-tokens)** to your monthly allowance per unit. Use this when you need to sync more content to your bots than your plan's storage allowance covers.

- **$5 / month** per 5,000,000 storage tokens
- **$50 / year** per 5,000,000 storage tokens

ℹ️

Token boosts follow the same monthly reset

Boosted tokens are added to your monthly allowance and reset on the 1st of each month along with the rest of your tokens. If you need the extra capacity every month, keep the add-on active and it will apply automatically each cycle.

## Capacity add-ons

These add-ons raise the structural limits on your account.

### Extra bot

Adds **one extra bot** to your team's bot limit per unit, so you can build more bots than your plan includes.

- **$8 / month** per bot
- **$80 / year** per bot

### Extra data source

Adds **one extra data source** to a bot's data-source limit per unit, so you can connect more sources of content to a single bot.

- **$4 / month** per data source
- **$40 / year** per data source

### Extra team member

Adds **one extra seat** to your team member limit per unit, so you can invite more people to collaborate.

- **$2 / month** per seat
- **$20 / year** per seat

ℹ️

Not available on personal teams

Personal teams are limited to a single member. To add teammates, switch to a team account first, then add extra team member seats as needed.

### Custom domain

Adds **one custom domain slot** to your team per unit, letting you serve a bot's chat widget and embed from a domain you control (like `chat.yourcompany.com`) for a fully white-labelled experience. See the [custom domains guide](https://chatthing.ai/docs/custom-domains) for setup steps.

- **$25 / month** per domain slot
- **$250 / year** per domain slot

🚨

Remove domains before reducing this add-on

Each slot maps to one live custom domain. If you want to reduce the number of Custom Domain add-ons, remove the extra domains first, otherwise the change will be rejected.

## Connected email account

The **Connected email account** add-on ($10 / month or $120 / year per inbox) is handled a little differently from the add-ons above. Rather than buying it from the billing page, it is added automatically when you connect an inbox for the [Email power-up](https://chatthing.ai/docs/email-power-up). See that guide for details on connecting a provider and how it's billed.

## How you're billed for add-ons

- Add-ons are billed on the **same frequency as your plan** — monthly add-ons if you pay monthly, yearly add-ons if you pay yearly.
- When you **add or increase** an add-on, the change applies immediately and you are charged a prorated amount for the rest of your current billing period.
- On a yearly plan, the monthly cost of add-ons is prorated across the remaining months of the year.
- When you **remove or reduce** an add-on, the change is reflected on your subscription and your next invoice.

## Managing your add-ons

1. Go to your [billing page](https://staging-app.chatthing.ai/app/billing).
2. Find the add-on you want in the add-ons section.
3. Set the quantity you need (0 removes it).
4. Click **Update addons** and review the change summary, including the new cost.
5. Confirm to apply. You may be redirected to the billing portal to confirm payment.
