In my opinion, this is the best post-purchase upsell app.
37% CR for the last 2 weeks. Literally free profit.

I used this app to discover which product on my store was the best to be on post purchase upsell, and the app did a great job.
It tested a lot of combinations and find out which product has the most %CR and % Profit Margin and generated us a lot of money.
Really easy to install (in few clics) and works well ! thanks a lot

We're happy the app worked so well for you, thank you for the awesome review!


I have tried in the past One click upsell, but it was slow when I was creating offers and It was slowing my website with 1.1secs. After that, I was testing different apps out there but none of them do the job. When I found I was skeptical because of the "AI" part but I decided to give it a try. After a few days later I started seeing an increase in my AOV. The most impressive thing was when offers that I wouldn't think to create were performing really nice with the algorithm that Upsellin provides. I've tested my store speed and it wasn't slowing down, which is crucial for me. I don't want to compromise on website speed when using apps. And the most insane thing for me was after installing and using the Upsellin app, I only had in the UI what I needed: Performance Metrics & Status of the algorithm how to perform, simple as that. At last, an app with "AI" inside their name worked!
