To protect your organization's data and the number of paid seats used in your organization, you can allow only owners to invite outside collaborators to organization repositories.

Note: This feature is only available on GitHub Business Cloud. For more information, see "GitHub's billing plans."

You can allow members to invite outside collaborators to repositories or you can restrict outside collaborator invitations to organization owners.

Adding an outside collaborator to a private repository will use one of your organization's paid seats. For more information, see "About per-user pricing."
