Amazing customer service. Ty has been super service oriented, and suggested some best practices to get us off to a good start. I'm looking forward to seeing how this pans out, and will be tracking our AOV closely.

Tactical Keychains

Easy to set up and quick customer service that is not a robot! We will be using this for the first time this week and we will see how much more revenue it helps on our orders.

B&B Labs Cosmeceuticals

This apps is powerful, not to mention that the live support, Ty is super fast, friendly, and efficient.


Highly recommend this app for higher conversion rates. Customer service is great and I usually have a response for any queries within minutes. Definitely recommend if you like a place for your cart upsells and campaigns to be all-in-one.

I can't speak more highly of the team at Monster Upsells, especially Ty! He was so helpful, AND SPEEDY, in getting my customised cart up and running and I'm really excited to see how it improves my AOV!

Thanks for the kind words 🙏🏻

Time for some EPIC UPSELLS! 🔥


Es muy fácil de configurar y el servicio al cliente es una joya. Sin duda recomiendo la app. Shootout to Ty for helping us!

Minx Bronzing and Cosmetics

Ty & the team at Monster Upsells go above & beyond to assist with intergration. We had a few issues as we are B2B & B2C - however it was an easy fix with a couple of the apps talking to each other. Monster Apps after sales support is like nothing that we have experienced before & we have had our Shopify store for 7 years
We just need them to come out with more apps :)

Curl Keeper - Curly Hair Solutions

Super easy to use and set up was a breeze! Lots of bells and whistles for a reasonable price! Would definitely recommend it!
