I have eBay linked to my Shopify store. Shopify is configured correctly and when I receive an order through my website, it calculates the sale including 10% GST (example, item $100 + $10 tax = $110). When I get a transaction through eBay, it records it as GST Free in Shopify because eBay is not flagging the tax, it's simply saying (example, item $110, no tax)... Therefore Shopify is recording the $110 as having no tax.. changing these invoices manually is very time consuming as I have to remove the payment and repply... this is making my accounting impossible and I have had to halt recording these transactions.

Can anyone help?
