To set up zonal shipping go to Settings > Shipping on your QuickBooks Commerce account.
Click on New Shipping Zone. Choose the Zone name from the dropdown options. Then add the countries to ship to from the following dropdown.
You can specify regions and provinces to ship to within each country selected. In this example, we use NSW, Australia.
Apply the changes to specify the provinces/regions for that country.
Once you have set up your shipping zones you can set up price-based shipping rates. Simply name the shipping rate, add a minimum order price and maximum order price if needed as well as the rate price. 
If you leave the shipping rate field empty, it will be displayed on your documents as well your B2B store as “FREE”.
Next, you may add weight-based shipping rates. Add the minimum order weight and maximum order weight as well as the rate price.
Once you are done, select “Save Changes”.
You will be able to see all of your shipping zones set up under Settings>>Shipments. You can also create a New Shipping Zone from here if needed.
