Currently, the only way to integrate funnels (upsells and cross-sells) is through the app “Appsell” which is amazing that it’s finally an option however, I would love the funnel option to extend to the other forms of checkouts as well such as bookings, pricing plans, etc as Appsell only seems to integrate with the Wix Stores checkout.
There were similar issues with the tracking capabilities for affiliate software options.
I’ve emailed Appsell to see if it’s possible for in the future to have it work with all checkout options, but as a couple have suggested over the years a native funnel option within Ascend I think would be fabulous and really hold Wix at the top of the website building game of doing it all.
