You can create as many Credit Terms as you need (with special due period, charge rate, etc.).
To add a new Credit Term:
Grace period - the period that starts after a Subscription period expires. The grace period can be considered as additional chance for a debtor to renew his (or her) Subscription. During Grace period, a Provider already has the right to suspend services. After Grace period runs out, a Provider terminates Subscription. By default, the minimal Grace period is one day.
Expiration period - the period of time an expired subscription is stored in the database. After an expiration period is over, a subscription is deleted, i.e., all the data related to a subscription is lost.
Renewal order period - The period of time remaining before a subscription expiration date when a renewal order is generated. By default, the minimal duration of the order renewal period is one day.
Subscription Termination Terms - the period of time a terminating subscription remains in the Account Director > Subscription Manager > Subscriptions > Termination Queue. It is possible to explicitly set the method of subscriptions termination for each of the available subscription periods and for trial subscriptions, three variants of termination method are available for each. To select the termination method, set the option button to one of the variants:
Terminate immediately. This option allows terminating a subscription automatically, right after a subscription termination is requested. In this case, a subscription is even not placed into the Termination Queue.
Note: When creating a new Credit Terms, please remember that an Order validity period should exceed the Renewal Order Period. Otherwise, a renewal Order can be cancelled automatically before subscription expiration date.
