TOS-TIER-002Not included in your planYou have reached a plan limit
What happened
Your tier includes a fixed number of locations or staff, and adding this one would exceed it.
What to do
Remove an unused location or staff member, or add capacity from the billing screen.
This is a permissions or plan boundary rather than a mistake — someone else can lift it.
Quote this code when reporting the problem. It identifies the exact check that failed, which the wording alone does not.
