Subscription benefits begin from the date you subscribe, and billing starts the same day. The 90-days-free period and the 2 bonus credits are exclusive to subscribing at checkout, so they don’t apply to a later subscription. Partner offers are available only during an active subscription, and your credits start accruing from the month you join. The 90-day unlimited revision window that comes with your package purchase runs from the date your documents are delivered and is independent of your subscription status, so you don’t lose that regardless of when you subscribe.
