If you choose to sell subscriptions on Subsail, you can set up both renewing and non-renewing subscriptions.
With renewing subscriptions, there is no set subscription interval; renewals and their charges are made on dates you specify for each issue. This avoids forcing you to charge subscribers every x amount of months or years and instead lets you time renewals perfectly in line with your issue releases.
You can choose the length of each subscription, which determines how many issues are included in each renewal. For example, a subscription with a length of three will charge the subscriber three issues and won’t charge again until the fourth-from-now issue is released. You can also choose to make your subscription have a length of one, which will charge subscribers as each issue is released. In Subsail terms, these are called rolling subscriptions.
You can start selling renewing (or non-renewing!) subscriptions from your account’s Sell page.
