Each client has a status on your team. It combines whether they've joined and whether their subscription with you is in good standing.

StatusMeaningWhat to do
InvitedYou've sent the invitation but they haven't accepted yet.Resend if needed. Nothing can be scheduled until they accept.
ActiveThey've joined and either have a paid subscription with you or are on a free package.Schedule, chat and coach as normal.
Awaiting paymentThey've joined a paid package but haven't completed checkout, or you moved them from a free package to a paid one.They see a Checkout button on their Billing page. Nudge them in chat if needed.
CancellingTheir subscription has been cancelled and ends at the end of the current billing period.They keep access until then. Either of you can resume it before it ends.
DisabledYou removed them from your team.Their history is kept, but they no longer have access. Invite them again to restart.

Tip: A client can be on more than one team, so the same person may show different statuses with different coaches.
