How to create orders with VAT / GST
In order to have WP-Lister create orders in WooCommerce including VAT / GST, it's not sufficient to simply enable it in your listing profile. Unlike sales taxes, VAT / GST is only used by eBay to be displayed on the listings page - it has no effect on any calculations nor does the eBay API provide this information for a particular order or order line item.
That's why WP-Lister needs some additional information, which is provided at eBay -> Settings -> Advanced in the Order Processing section.
To create orders with VAT / GST you need to select at least a VAT tax rate - and it is recommended to set your VAT rate (percentage) as well, so it can apply the correct tax rate even if the purchased item does not exist in WP-Lister.
