Why should I keep using Addition if Australia Post has launched their own Shopify app?

Australia Post has recently released a direct integration for Shopify, but there are a few key differences merchants should be aware of before switching.

1. Limited to MyPost Business (for now)

• The current integration only supports MyPost Business accounts.
• eParcel/Parcel Contract and StarTrack accounts are not supported yet (though Australia Post says this is “coming soon”).
• Addition already supports MyPost Business, eParcel, and StarTrack under the one app, so you can manage all accounts in one place.

2. Fulfillment only, no checkout rates

• The Australia Post app is designed just for label purchase and fulfillment.
• It does not provide live checkout rates for your customers.
• Addition lets you show accurate Australia Post rates (Parcel Post, Express, International, etc.) at checkout, including custom rules, surcharges, and discounts depending on what plan you are on.

3. Shopify plan restrictions

• The Australia Post integration is only available on eligible Shopify plans:
  • Shopify Plus ($2,300USD/month*)
  • Advanced ($399USD/month*)
  • Grow ($105USD/month*)
• It is not available on Basic or Starter plans.

In summary:

If you’re on Basic/Starter Shopify, using eParcel or StarTrack, or you need live checkout rates, insurance, signature options, or bulk fulfillment, Addition is still the better choice. The Australia Post app may suit very simple MyPost Business setups, but Addition gives you flexibility, advanced shipping logic, and support for all Australia Post account types.
