Renewal extends or replaces access under the service's actual purchasing and account rules. It can be manual or part of a separately agreed recurring arrangement. The new period's start, existing account handling and any price changes need to be understood before purchase, because renewing is not always the same as creating an unrelated new account.
A practical example
A customer renewing an existing term should identify the intended account and requested duration privately. Confirming the resulting expiry helps distinguish a successful extension from a separate new order or a payment still awaiting the service's normal processing.
A common misunderstanding
Do not assume remaining days are always added, credits are deducted in a particular way or the original price is permanent. Use the actual renewal terms for the relevant account.
