# What happens when I run out of seats?

Your bill never grows on its own — it's **block-and-buy**. When every seat is taken, new invites
are simply **blocked** until you make room, and nothing is charged and no one loses access until
you decide to add seats. To fit another teammate you either buy add-on seats or remove a member
or pending invite on the **Team** tab. (On an operator-provisioned or contract plan, seats are
arranged through support rather than self-serve.)
