Per workspace, not per seat

You pay for usage, never per seat.

Per-seat tools bill you for every person used or not. Additional bills for what your team actually uses, so adding teammates is always free and your cost tracks value, not headcount.

Per-seat tools

Additional

At the same usage, a per-seat bill multiplies with every person; Additional doesn't. You're billed on usage (base + $0.02/extra message, capped) never per seat. Illustrative vs a typical ~$20/user plan.
