What's Inside
One row per plan: price, what's unlimited, what's metered, the window, and what happens when you hit it
Read from the vendors' own pages, re-checked every Monday. Where a vendor publishes no number, the cell says so
What to do when you hit the cap: the order I try things in, with the real credit prices and the seat math for a team
Re-sent when a limit moves, so the copy in your inbox is never the stale one
No spam. A new sheet only when a limit actually moves. One-click unsubscribe.
