Physical products vs service or digital products
It's possible to sell digital products or services on Shopify that don't require shipping, but if you have downloaded our app you probably have physical items that do require shipping.
It's important to make sure your physical items are flagged as physical items so the Australia Post Shipping app recognizes they need shipping and is able to display rates for them.
While making or editing a product, make sure to check the option 'This is a physical product'.
How to check a product is a 'physical products'
Go to your Shopify Dashboard. For example: yourshopname.myshopify.com
Click Products in the left menu.
From the list of items, select one to check.
Scroll down to the 'Shipping' section, and you'll see the 'This is a physical product' check box.
Make sure this box is selected on all products that are physical items so our app knows they need shipping.
