Direct Sellers can select which billing cycles should be available to their customers.
As available options are:
When purchasing an offer, the customer will only be able to select the billing cycles which direct seller enabled. If an offer doesn’t have any of the billing cycles which have been enabled, it will be hidden.
Select the "Settings" tab, on this page, select Billing & Payments -> Billing.
Choose which billing cycles you want to support. If a new billing cycle becomes available for a license in your catalog, you will be able to enable it here manually.
One or several valid charge period values can be selected.
