Software architects warn against conflating membership and subscription data models

A software developer observes that teams often mistakenly model membership programs as subscriptions, leading to costly rewrites. The core distinction is that a subscription is a commitment to receive goods on a schedule, while a membership is a commitment to a relationship granting access. Key differences include decoupled billing and fulfillment cycles, separate definitions of churn, and the need for independent entitlement management. Using a subscription model for a membership system creates ongoing conflicts in representing status, tracking engagement, and applying access rules.
