If you're not using all of your organization's paid seats, you can downgrade to pay for fewer seats.
Your organization's number of paid seats must equal the number of organization members and outside collaborators or bots that have access to any of your private repositories. If you'd like to pay for fewer seats, you can remove members from your organization or convert members to outside collaborators and give them access to only public repositories, then downgrade your organization's number of seats.
