What does "The correct amount of tax is charged automatically." exactly mean in https://help.shopify.com/api/charging-for-your-app?
As example: Don't we have to add taxes to our app charges if we're as a Swiss company charge a Swiss Shopify user? Who do we actually charge? Is it the Swiss Shopify user or does Shopify act as middlemen and thus is it always a Canadian company we charge and they handle taxes with the Swiss Shopify user?
