Scored on 42 merchant reviews we hold for Cart X ‑ Post Purchase Upsell, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 42 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 42. Open one to read it in full, with the developer's reply where there is one.

Really good app to prompt customers to add optional parts to their cart. It saves them receiving a product and then being disappointed they didn't realise they needed to order the other bit (which is sold separately by the manufacturer) Tech support by Arthur is very good as well

Had a problem which was fixed by Patrick. Really helpful and he gave me additional tips to help improve the performance.

I love the ease of set-up and the detailed customization! Arthur was a rockstar in assisting me with vids to show me exactly what I needed. Great App!! You'll love it too.

Cart X is a good post purchase upsell app. It helped increased my AOV and easy to use. Their client support Marc is very responsive and whenever I have a problem, Marc will help me solve it. I suggest you try it out and you will love this app.

I use this app to offer my clients new products after their inial purchase. I am happy with it. The client support of Cart X is really good and Marc helped me to set up my funnel to increase my sales! Very appreciated

Très bonne application qui permet d'ajouter plusieurs upsells en meme temps, ils ont un très bon service client Marc était la pour m'aider à configurer le funnel . Merci :)

Amazing app, It helped me scale really quickly with their upsells. Customer service is amazing too. Really recommend this app to anyone trying to scale

Bon service apres vente, reactif app facile a mettre en place jai 2 ans dexp dans le drop et je recommande merci bonne journee Dan
