ย
II. Operational Logicย
Early Renewal
The customer's current subscription is still active, and the renewal is completed before expiration.
The new 12-month term starts from the original expiration date, so the customer does not lose any usage days. This option offers the lowest price.ย
Renewal
The customer's subscription has expired but for less than 12 months.
The new term starts from the actual renewal date.
The gap between the expiration date and the renewal date will be automatically aligned by the system, with no adjustment required.ย
Reactivation
The customer's subscription has been inactive for more than 12 months.
The new term starts from the reactivation date.
This is the highest-priced option (designed to encourage customers to maintain continuous subscription).
