Goal: Let WL partners offer one-time bundled minutes add-ons on plans that already include monthly bundled minutes, so sub-accounts can buy extra minutes without changing tiers.
Key points:
- One-time top-up purchases for monthly bundled minute plans
- WL partner can configure top-up packages per plan (example: +100 mins, +300 mins)
- Charge top-ups using the client’s saved billing method
- Show remaining bundled minutes plus purchased top-up minutes clearly in the dashboard
- Track top-up purchase history for billing and usage reference
