| Entitlement model |
Access rights are often implemented outside the billing layer or attached to plan logic. |
Access rights sit at the center of plan, offer, storefront, and lifecycle behavior. |
Map plans and add-ons to access bundles before cutover. |
| Lifecycle control |
Billing states, dunning, and subscription events are managed around billing workflows. |
Lifecycle state is shared across billing, payments, offers, retention, and support workflows. |
Reconcile active, paused, cancelled, trial, failed, and grace-period states. |
| Storefront handling |
Multi-storefront behavior may require configuration patterns and outside services. |
Storefront, brand, region, and channel rules are first-order operating controls. |
Group subscriptions by storefront ownership and cutover boundary. |
| Payment control |
Payment provider behavior is usually connected to billing operations. |
Provider routing and retry policy are management decisions by market and channel. |
Separate payment references from routing policy before go-live. |
| Migration complexity |
Plans, add-ons, coupons, subscriptions, invoices, and dunning history need mapping. |
Source data becomes continuity history for governed future operations. |
Validate plan-to-entitlement mapping and recovery-state continuity. |
