How to Add and Delete Fulfillment Services
Shopify lets you use fulfillment services if the warehouse that you’re using is able to process orders by email. Otherwise, you’ll need to develop a custom app with a Shopify API developer.
To activate a fulfillment service, follow these steps:
Step #1: Go to the “Shipping” section of your Shopify “Settings” menu.
Step #2: Click “Add Fulfillment Service” in the “Custom Order Fulfillment” menu of “Additional Shipping Methods.”
Step #3: Enter the name of the fulfillment provider and their email address in the pop-up form.
Step #4: Save your changes and add the service.
When a product or order has been marked as fulfilled, the service will be notified via email so they can fulfill it for you.
Deleting a fulfillment service is simple. From your “Shipping” page, just click “Edit” next to the service you want to remove, and click “Delete” from the pop-up.
Note: Fulfillment services will not ship items for you until the order has been marked as fulfilled on Shopify.
