We are yet to launch this product but WPFunnels is by fart the easiest Sales Funnel builder in WordPress. It comes with a built-in drag & drop funnel mapping canvas and every feature you need to build complete sales funnels without leaving the WordPress dashboard. It will allow users to use order bumps, upsell & downsell offers, and conditional redirection to increase sales in business. Currently, we are beta testing the plugin and are planning to release it in a week or two.
