How to mark an order as fulfilled
Once you have created your labels and shipments are ready to send, you should mark your orders as 'fulfilled' in Australia Post Shipping and your Shopify store.
If it's not already open, navigate to the fulfillment you're working on by clicking Fulfillments on the left navigation menu of Australia Post Shipping, and selecting the fulfillment you need.
Next to 'Fulfill orders in Shopify' click Fulfill Orders.
Here you will see a list of the orders making up the fulfillment. Click Fulfill Items.
You will see a 'Congratulations!' page. Your products will now be fulfilled in Shopify and your customers will be notified with tracking details.
Now those orders will appear in Australia Post Shipping and Shopify tagged 'Fulfilled'.
