Order management and fulfillment
To process orders in your online store and sales channels, you need to set up your order fulfilllment and shipping settings, such as shipping rates, locations, and shipping profiles. After you receive an order, you can manage and fulfill your orders from the Orders page in your Shopify admin.
To save time and money on order fulfillment, you can use Shopify Shipping to buy and print shipping labels from your Shopify admin.
If you want to fullfil your orders using a fulfillment center, then you can use the Shopify Fulfillment Network.
