How To: Manage Shipment Statuses
If you go to Orders → Shipments, you will see all the list of all shipments in your store. Shipments have statuses, allowing you to sort the list, or to search for shipments with a specific status.
By default, there are 3 statuses: Packed, Picked up, and Shipped. However, you can edit them, or add your own statuses.
Shipment statuses do not affect anything—they only help you manage your list of shipments.
