+## 7) Key Implementation Rules + +1. **Invoice type drives fulfillment** (no plan/package hardcoding). +2. **Subscription credits**: reset to **0** at cycle end, then set to **full amount** on renewal. +3. **Credit packages**: add package credits only. +4. **Credit invoices**: expire automatically and are cancellable by users. +5. **Account status** only changes on **subscription invoices**. + +--- + +## 8) Operational Verification Checklist + +- Stripe/PayPal subscription purchase activates account and resets credits. +- Bank transfer subscription approval resets credits (not adds). +- Credit package approval adds package credits (not plan credits). +- Credit invoices do not block subscription state. +- Credit invoice expiry and cancellation work with emails. +- Renewal resets credits to 0 at cycle end and to full on payment. + +--- + +## 9) Extensibility (Future Add‑ons) + +- Add new `Product` types without code changes to invoice fulfillment. +- Use `invoice_type='addon'` with line items to provision entitlements. +- No plan/package hardcoding required. + +--- + +## 10) References + +- Audit:
