# Update tenant tier

<Snippet file="graphql/sdk-note.mdx" />

If you want to explicitly set the tier for a tenant you can do so using this mutation. If instead you want to add many companies to a tier at once, you can use the [add members mutation](./add-members).

For this mutation you need the following permissions:

* `tierMembership:read`
* `tierMembership:create`
