The subscription is charged / invoiced in advance. Please note, however, that if the subscription starts in the middle of a month, it will be debited per day that month, and the amount will be added to the bill for the next month. Card debiting takes place on the 17th and invoices are sent out on the 16th of each month. As a new customer, the paper invoice is the default payment method. Payment method can easily be changed on My pages.
