Prepaid subscription orders are paid for in advance but have scheduled fulfillments over a period of time.
Prepaid subscription orders have a Scheduled status until the fulfillment date is reached.
When the fulfillment date is reached, the order status updates to Unfulfilled and you
can then fulfill the order.
The order's status then changes back to Scheduled until the next fulfillment date is reached and the cycle begins again.
When an order has a Scheduled status, you can track the order on your Orders page in Shopify admin, but no action is required.
On the order, you can review all items for the prepaid subscription orders, sorted into Fulfilled, Unfulfilled, and Scheduled fulfillment cards. The next scheduled fulfillment for the order is listed in the Scheduled fulfillment card. Click View all fulfillments to display all scheduled fulfillments.
