Hello,
If you have products on your site it means that you use the WooCommerce plugin, you need to contact WooCommerce plugin support here https://wordpress.org/support/plugin/woocommerce/ in case you want to change something in the default plugin functionality.
It’s possible to improve also by additional customization of the child theme but then you need to order an additional customization service here. Basic support does not include additional customization https://themeforest.net/page/item_support_policy
