Billing Cycles Shape Prediction Windows

Predictive churn work collapses when feature windows ignore commercial rhythm. An annual subscriber three weeks before renewal behaves differently from a monthly user on day five.

Anchor evaluation to days-to-renewal and days-since-activation, not only calendar date. Report precision separately for trial-to-paid, monthly, and annual segments.

Intervention timing should follow the same logic. An outreach that lands the day after renewal for an annual plan is a year too late; the same message two weeks before can still save the account.

App analytics already hold the behavioural half of the story. Billing metadata holds the clock. Use both.
