Subscriptions are always paid in advance. If it is monthly, the day you pay, access is granted for the next month. No renewal means you want to discontinue the service and we will accept your decision. Invoices are issued and sent upon payment to avoid credit notes in case you decided to discontinue the service.
Our recommendation: unless you are still hesitating about the benefits, the best alternative is to pay 12 months in advance to get 10% discount and save all the associated costs to each payment.
