The right a customer holds to use a product, feature, or quantity. The single record subscriptions, gateways, and apps read to grant or deny access.
An entitlement says what a customer is allowed to do: access a tier, use a feature, consume a quota, watch a region, or use a number of seats. Entitlements come from subscriptions, one-time purchases, trials, or grants.
Mixing access logic into payment flow or storefront code creates conflicts. When two systems disagree on access, customers get blocked or over-served. Entitlements as a separate record let payments, apps, and partners all read the same answer.
Entitlements are first-class objects, scoped per tenant, per channel, per product. Subscriptions, bundles, prepaid balances, and trial rules all write to entitlements. Apps read entitlements at runtime through one API.
