Creating a sales funnel for upsells

Hey! I want to create a sales funnel with Webflow, but I’m not sure how to go about it. I’m sure i’ll have to do some work around because this is not native to Webflow, but i really want to do this.

The idea is that a customer buys something and instead of going to a thank you page they go to a page with an upsell, an “exclusive offer” only available because they purchased something before.

The idea is to keep it inside Webflow, not using any other apps or integrations

Has anyone done something like this?
