Why should I connect a courier to my site?

If an order requires you to ship products to a customer then you may need to copy orders details into a courier application in order to select the correct service and create courier labels once you have fulfilled the order. This creates double handling that can be reduced by connecting a courier to your site.

Once a courier has been connected then additional functionality in the order fulfillment process allows you to validate shipping addresses, select courier rates and add-ons and create your courier labels, all thats left is to package up your orders, stick on the labels and request a pick up.
