Plan and billing cadence
Monthly and annual customers face different renewal moments. Analyse them separately before comparing acquisition channels or product usage. A blended curve often reflects plan mix more than customer quality.
Payment route and recovery path
Payment behaviour can vary by method and operational flow. Group customers only where volumes are sufficient, protect privacy, and avoid inferring intent from the payment method itself.
Customer maturity
First renewal, second renewal and established subscribers usually behave differently. Tenure cohorts help teams avoid applying the same message or forecast assumption to every customer.
