AK TOOLS review for Shopify Marketplace Connect

I need a simple app to sync orders from eBay/Amazon to Shopify , this app does it , but it lacks of the tax features, the GST tax line doesn’t get pass through from eBay / Amazon, therefore tax invoice generated without the GST amount, other app like Salestio allowed the user to configure the tax override for the import order to derive the GST from the Unit price.
