Please consider Listivo do not support WooCommerce Plugin shop functionality (add to cart / checkout / purchase). Listivo has WooCommerce Payment Gateways integration. It can be used to process payments when users submit listings to your website e.g. to charge visitors an extra $10.00 for making the listing featured for 7 days on your website.  Here is the full article on how it works:
