Payments for a one-time ("annual") membership are immediate on registration. These memberships do not auto-bill and will not renew automatically. Access to the MMQ content for your subscription year(s) is permanent even after the project year has ended.
Payments for a recurring ("monthly") subscription payment begin with the first payment as soon as the subscription begins. Subsequent payments process automatically on the same day of the month as the date of the first payment (for example, if you begin your membership on November 14, then your next payment will be December 14, followed by January 14, etc). Recurring payments continue until all twelve payments are made. Subscriptions do not automatically renew at the end of the year; when the final payment is made, an automated email will alert you that your "subscription has ended," but your access to the content through your MMQ account is permanent.
