CHW-4415 BillingSeatsBelowMembers

Client Input Updated

seats must be at least the organization's current member count; remove members or buy more seats

Default message: seats must be at least the organization’s current member count; remove members or buy more seats
HTTP status: 400 (client)

Problem. /api/billing/checkout rejected the seats field for the Team plan. Cause. The requested seat count is lower than the organization’s current member count (the platform-operator seat is not counted; CI/service tokens are not members). Fix. Buy at least as many seats as you have members, or remove members first. HTTP 400.
