In Shopify, setting up Custom Fulfillment Services lets you specify which items should ship from specific fulfillment services. You can use this with Extensiv Integration Manager to identify which items Integration Manager should load.

Additionally when this feature is enabled and inventory levels are syncing through Integration Manager. Integration Manager will only sync inventory levels for items with the matching Fulfillment Service.

 

Set up: 

1. In Shopify setup a Custom Fulfillment Service for Integration Manager. Please click on this link and perform this step inside Shopify.  If you do not perform this step, it will not perform as expected. You may add others as well for your other systems or warehouses.
    
2. In Integration Manager, go to the Shopify cart settings and enable the Filter Orders By Fulfillment Service option.
    
3. Enter the name of the Custom Fulfillment service that you created in Shopify. Make sure the names match exactly.
    
4. Save.
    

At this point, Integration Manager will load only the items on an order that are flagged for the selected Fulfillment Service. Orders without any items for the selected Custom Fulfillment Service will be ignored completely.
 

When the warehouse ships order and reports back tracking, Integration Manager will only mark the items for the specified Fulfillment service as shipped. If an order has multiple Fulfillment Services, only the portion of the order that Integration Manager loaded will be marked as shipped.
