If you plan on expanding the subscription option for your clients, you might want to consider adding a Fixed-term subscription.
When you sign up for a service, for example, for a year and pay monthly, but find that you can't cancel during that time, it's called a "fixed-term contract" or a "fixed-term subscription." In this type of contract, you're required to make payments for the entire agreed period, even if you no longer use the service. This is unlike a month-to-month subscription, where you can cancel at any time without further obligations.
Another thing to be aware of is that fixed-term contracts automatically renew at the end of the agreed period unless canceled previously.
To turn this option on, please contact Customer Service.
