# Link Multiple Tenants to a Single Subscription

Auth0 offers the ability for customers with an Enterprise subscription to link multiple tenants under a single Auth0 subscription (these linked tenants can also be referred to as child tenants).

This feature can be useful under the following situations:

* Separate development and production tenants while keeping the same feature access on development tenants as available in production tenants
* Own more than one production tenant under a single Enterprise subscription

## Linking tenants

An Enterprise subscription automatically allows users to link tenants under an existing Auth0 subscription by selecting the **Custom Agreement** option from the **Create Under** dropdown when creating new tenants.

If you need to link previously created tenants that are not currently part of your Enterprise subscription, contact your account team or open a ticket with [Auth0 Support](https://support.auth0.com).

  If you have a self-service subscription (not Enterprise), you can still link tenants. To learn more, read [Tenant Management](/docs/get-started/auth0-teams/tenant-management).

## Usage consolidation

Usage from all linked tenants counts toward your Enterprise subscription limits. You can view aggregated usage across all linked tenants in your usage and quota reports.
