Fulfillment logic
Shipping and order fulfillment settings, such as order routing, fulfillable inventory, and fulfillment constraints, are applied across sources where Shopify orders are created and edited. This prevents unwanted overselling and ensures that orders are routed to the location capable of fulfilling the items, regardless of the order source.
The following order sources respect all your fulfillment and shipping settings:
- Orders created from Shopify's online checkout.
- Orders created from draft order invoices. Orders created manually from draft orders, such as mark as paid orders, don't block overselling.
- Orders imported from a third-party app or sales channel, such Shopify Marketplace Connect.
- Subscription orders.
- Order editing, such as adding new items to an existing order.
