Do not use it if you have multiple languages in your shop. The app has no translation possibilities included. You can only use translate and adapt which is highly limited in metafield data and will therefore not solve your problem. Very sorry, but unfortunately I cannot recommend this app. Support was also not bringing up any solutions that are applicable.

I had some questions due to my ATC, but they helped me very quick and even did some overdelivery, very happy! Happy customer!

The team was super helpful! Laura helped me fix my cart issue so quickly really appreciate her support, everything’s working perfectly now!

I’ve had the opportunity to see John’s work on advanced JavaScript projects through Upcart, and what stands out the most is his speed in approaching and solving problems. He doesn’t waste time overcomplicating things—he’s able to look at an issue, quickly understand what’s going on under the hood, and then move straight into building a solution. This makes him a great fit for situations where time is limited and results are needed fast. John’s strength lies in his ability to break down complex JavaScript logic into smaller, more manageable parts. Instead of trying to brute force fixes, he works step by step, testing along the way, which gives his solutions a solid foundation. For example, when tackling asynchronous programming challenges, he quickly identifies whether callbacks, promises, or async/await is the right approach and then implements it cleanly. This efficiency doesn’t just save time—it also reduces the risk of introducing bugs down the line. That being said, his speed doesn’t come at the cost of readability. His code is usually straightforward and easy to follow, which is especially useful when collaborating with others or passing projects along. He also has a good habit of leaving things in a state that makes future updates easier, which is something many developers overlook when they’re working quickly. In terms of debugging, John is equally fast. He has a strong sense for where problems are likely to be, and he doesn’t spend long hours chasing errors blindly. Instead, he uses a combination of testing tools, console logging, and systematic isolation of functions to zero in on the problem area. This methodical approach makes him not only quick but also reliable—fixes are thorough rather than temporary. One area where John could grow is perhaps in slowing down at times to add more documentation or explanations alongside his work. While his code is readable, a little extra context would make it even more accessible for people new to the project. But overall, this is a minor trade-off for the speed and effectiveness he brings to the table. Using Upcart with John’s contributions has been a solid experience. The app feels smoother, and it’s clear that his ability to quickly solve advanced JavaScript issues plays a role in that. He’s someone you can count on when complex tasks arise and deadlines are tight. If you’re looking for a developer who can strike a balance between speed, reliability, and clean JavaScript implementation, John is a strong choice. He’s not just fast—he’s consistent, practical, and focused on getting things working the right way.

I'm newish to Shopify and was confused about how the app worked. I ended up getting such quick and great customer service from the UpCart team. Totally a complete 180. Brandon and the team were truly so helpful!

Great app. Brandon chat support guy I got couldn't have provided me with a better service. Super polite, helpful, and most important fast and professional. Definitely recommend

Very helpful in assisting me with the configuration of the upsells. Even sent me a loom video to help explain one bit. Thanks Brandon

Michelle helped with with an issue I had and solved my problem immediately! It was late at night but she was there in the chat to help. Thank you!!

Very bad support, i have an issue with their cart since 6 days, still waiting for their technical support to even look at my issue. Only chat support asking me to wait until technical support is available, 6 days already i don't recommend this app at all.

This is a good app and the team provide good customer service. I wish it was a bit easier to set up (for us non-techies) but other than that happy with it.

The app has some great functionalities and the customer service was very kind in helping me fix some issues with translations

I installed UpCart mainly to offer rewards directly in the cart, and it's been super straightforward to set up. The interface is really easy to use, and I’ve been testing out the upsell and reward features. So far, I’ve already seen a few upsells come through, which is a great early sign. Shoutout to Hailey from the support team—she noticed I wasn’t getting anywhere with the AI bot and jumped in to help without me even asking. Really appreciated that kind of initiative!

The app has some good functionalities but also some pretty bad issues. We have had issues with not being able to control the rewards properly for different markets using different languages and currencies. And support seems to not really know much and just asks you to try out different things and hope for them to work.. Keeping an eye out for something better

Michelle from UpCart Drawer was brilliant! She was patient, extremely helpful, and we fixed the problem quickly. I wish I had spoken to her sooner, very happy with the experience.

Upcart is great if you want to increase your AOV. Team is very helpful and responsive. Def recommend.

It's worked really great for us so far - with some minor issues with compatibility. Recently we had an issue with the cart drawer showing up, and initially I was directly to an ai support who only re-parroted what I'd already read in the help guide and searched on chat gpt myself. However, once I asked for an escalation, I reached Patti who was able to identify a solution very quickly. Hopefully the app continues to be compatible with our store because it offers an easy way to boost sales and show offers before checkout.

Michelle did make a really good job, supporting and guiding me what i did wrong when setting up my upcart. She did a really fantastic job overall. 5 stars

The best cart app on Shopify App Store, period. Yes, it’s a little more expensive than others, but absolutely worth it. Front-end performance is noticeably faster than any other cart app I’ve tried, and it works right out of the box without needing a ton of tweaks. (Most other cart apps require you to manually disable Shopify’s native cart, otherwise they just stack on top as an overlay, this one handles it perfectly.) Customisation options are excellent, and the support team is genuinely outstanding- fast, patient, and willing to go the extra mile. In my very first week, they made custom adjustments for me, and since then I’ve had zero issues. Even when I caused a problem myself by changing something in my theme, Aina from their support team took the time to go through everything and help me fix it without hesitation. I’d recommend this app over any others, hands down. It simply works out of the box, and in my experience, it’s even faster than Shopify’s native cart.

Michelle was much faster to solve my problem. Thank you again! Apart from that, this application is perfect for a better conversion rate.

Amazing service. Helped with every question I had. Even helped me add some code in. Great app and people to work with!
