Our Verdict
Essential Upsell & Cross Sell is the stronger choice for most merchants due to its established user base (indicated by the large number of reviews), comprehensive feature set, and focus on automating and diversifying upsell opportunities. Its features cover the entire customer journey, and the automated discount promotions can further increase AOV. Checkout Catalyst's lack of detailed feature descriptions and minimal reviews make it difficult to assess its true value, and it is better suited for merchants who prefer a very basic tool and are comfortable being early adopters, potentially benefiting from a closer, more personalized app development and support cycle if such exists.
