How Locations work
Locations are a physical place from which you ship your products. You can specify multiple locations if you need, for example, if you have multiple stores, a pop-up site, or if you have a warehouse that you ship from separate to your office. Setting up locations allows you to track your inventory, quote accurate shipping rates and print 'Sender Details' on your shipping labels.
If you move location, open another store, or rent a warehouse, you'll need to either add a location or edit your locations. Locations are added via your Shopify Dashboard and will be reflected in Australia Post Shipping once you Resync Locations.
Editing Your Locations in Shopify versus Addition
You can edit locations via your Shopify Dashboard or via Addition. If you choose to edit your locations in Shopify, just remember that they will be reflected in Addition only once you Resync Locations in the app.
Edits made in Addition are not reflected in your Shopify admin, but they do override your Shopify settings. In other words, when the app is quoting rates to your customers at the checkout or using location information for order fulfilment, it will take preference for the location information you have input to Addition over the Shopify location.
NOTE: If you click Resync Locations after you've made edits to your locations in Addition, those edits will be lost, and all location settings will revert to those you have set up in Shopify.
Setup your locations
Once you've installed Addition, you will want to ensure your 'Locations' are also set up in the app.
From the Addition dashboard, click Settings.
Click Locations, then Resync Locations to refresh the list of locations.
You'll see a refreshed list of the locations you have setup in your Shopify admin.
