When a patient's subscription payment fails, the platform automatically retries the payment — up to three attempts, one day apart.
If the retries are unsuccessful, the subscription is set to inactive. Note that the patient's own status does not change — a patient whose subscription has gone inactive will still appear with whatever status they had before (for example Active).
Because of this, clinics should monitor subscriptions themselves rather than relying on the patient's status. Open each patient's Treatment Plans tab to see whether their subscription is inactive — there is no clinic-wide subscription report — then deal with those patients directly, for example by moving them onto pay-as-you-go.
