Preorders placed through the PreOrder Now app are treated as regular orders in Shopify.
This means:
There is no special handling of preorder items.
Orders with preorder products are processed like any other order.
They are sent to your shipping app or third-party logistics tool the same way as standard orders.
⚠️ Important:
If an order contains both preorder and non-preorder items, your fulfillment process may be affected. Be sure to account for this when setting up your shipping workflows.
