# How do seats work?

Seats cover **editors and admins** — the people who create and manage your docs. **Readers are
always free and unlimited** on every plan. Each plan includes a set number of seats (Free 1,
Pro 5, Business 12, Enterprise unlimited), and on Pro and Business you can buy **add-on seats**
when you need more: **$10/seat/mo on Pro**, **$15/seat/mo on Business** (annual plans bill seats
at 12× the monthly rate, so the yearly total matches the monthly one).
