Subscription Billing

Plans, trials, proration, dunning, and a self-service portal that does not leak churn.

Subscriptions look easy until somebody upgrades mid-month, fails their next charge, and disputes the partial refund. We design for the full lifecycle, including the customer self-service portal.
