# Upgrade or downgrade your plan

> How plan changes work, what happens to your features, and when changes take effect.

Plan changes are made by an Admin in **Settings → Billing**.

## Upgrade

Upgrades take effect immediately. You gain access to the new plan's features right away, and your card is charged a prorated amount for the remainder of the current billing period.

### After upgrading

* **Custom domains** — You can configure custom domains for your projects right after upgrading.
* **Analytics** — The analytics dashboard becomes available immediately. Historical data from before the upgrade is not backfilled.
* **AI search** — Enable AI search per project in project settings after upgrading to Growth.

## Downgrade

Downgrades take effect at the end of your current billing period. Until then, you continue to have access to all current plan features.

When the downgrade takes effect:

* Custom domains are disabled — your site will redirect to its `*.mintlify.app` URL.
* Analytics and AI search features become unavailable.
* The site itself stays live and deployments continue.

### Before downgrading

Export any analytics data you want to keep — historical data is not accessible after downgrading.

## Billing contacts

Make sure the billing email on file in **Settings → Billing** is monitored. Invoices, receipts, and renewal notices go to that address.

If your billing contact changes (someone leaves, finance wants a shared inbox), update the billing email before the next renewal cycle.
