# Members and invitations

> Inviting people, what happens when they leave, and where seats are counted.

## Inviting

**Organisation → Settings → Manage members → Invite by email**. An invitation
is sent by email with the role you chose. It can be revoked before it is
accepted.

Inviting requires the `member.invite` permission. Owners and admins have it
implicitly.

## Seats

Members consume seats against your plan, and a pending invitation reserves a
seat until it is accepted, revoked or expires. The seat count and what is left
are on the organisation's **Plan & seats** page. Seats are changed from
[Licensing & Billing](/foliums/blueprintr-user-guide/account/billing-and-usage),
not from the members page.

An organisation with no active licence cannot invite anyone. See
[Setting up an organisation](/foliums/blueprintr-user-guide/teams/setting-up-an-organisation).

## Removing someone

Removing a member (`member.remove`) revokes their access immediately,
including anything derived from their membership, such as access to team
content and any custom roles they held.

> [!IMPORTANT]
> Content they authored stays with the organisation. Removing a person removes
> their access to it.

## Joining through SSO

Where [SSO](/foliums/blueprintr-user-guide/enterprise/single-sign-on) is configured, people
sign in through your identity provider instead of accepting an invitation. With
[SCIM](/foliums/blueprintr-user-guide/enterprise/scim-provisioning), membership is
provisioned and deprovisioned automatically from your directory.
