Fulfillment Network
Fulfillment Network is a fulfillment service app that you can use to integrate with a service that stores your inventory and fulfills orders. To offer this fulfillment service, Shopify partners with multiple third-party logistics services (3PL).
You can sign up with a 3PL through Shopify by using the Fulfillment Network app and outsource fulfillment to a 3PL in your Shopify admin. After you're set up, you can monitor inventory transfers and track order fulfillment without leaving the Shopify admin. When you receive an order, your 3PL picks and packs your products and ships them to your customer.
