By default, Easyship immediately sends a fulfillment status to your store upon shipment generation. This article describes how you can customize fulfillment behavior.
How to Update Store Fulfillment Settings
Step 1: Navigate to your Store Settings by clicking on Connect, followed by your store name in the left-hand column.
Step 2: Expand settings in Order Sync. 
Step 3: Scroll down to Update order status to change the configuration.
If you have a warehouse integration, you will have an extra option to mark the order as fulfilled when the warehouse hands it over to the courier or within 24 hours, whichever occurs first.
