Dating no online subcriptions
There are two kinds of Active subscriptions: Within a term and Out of a term.
For example, there is no way to change the expiration date on a subscription created with Pay Pal Standard.
To allow customers to do this, first, you need to setup switching. Customers can now use the normal upgrade process to choose a longer subscription.
Although the two methods above allow your customers to extend their subscriptions, they both create a new subscription with the extended expiration date rather than simply changing the expiration date on the existing subscription.
The required trigger dates can vary by product and can be configured using the Default Subscription Settings.
If your company's default subscription settings have Require Customer Acceptance of Orders? set to Yes, you must enter those dates to fully activate the subscription.
