The Finch Cart – Product Recommendations is an addon for WooCommerce. So it’s required to have the WooCommerce plugin installed and activated on your site.
If your site doesn’t have the WooCommerce plugin installed, make sure you install and activate it first.
After that, you will see the Finch cart menu in the admin area, here you can adjust the product recommendation settings.
