1. Review the account journey.
Identify the offer, provider, application and event causing the problem. Use a safe summary before reviewing private billing evidence.
Process
Write the expected customer outcome first.
Use one subscription scenario to make the billing, communication and access rules concrete.
2. Agree the rule.
Document the intended effective date, invoice treatment, customer message and service access. Business owners approve commercial terms and exceptions.
3. Map the provider and application states.
Identify the events and records used to update the account. Review missing, repeated and delayed updates.
4. Test a lifecycle in isolation.
Use provider test facilities and sample accounts for the agreed renewal, failure, plan change or cancellation. Check both the billing records and the customer's application access.
5. Release with a handoff.
Agree production changes, recovery conditions and ownership. Give support staff instructions for recognizing and reviewing exceptions.
