I highly recommend Upsell plus. Not just for the smoothly integrated Upsell buttons at checkout, but the customer service is unmatched. They got all of my products completely set up, and helped me make any changes. I have dealt with other third party apps that were impossible to get a hold of. Not these guys. Best service ever and a good product. And it has already lead to more sales.

Excellent App! Does what we need it to do without being obtrusive. We have seen massive ROI on the investment that we have made. Has a few features that we have not been able to find in other checkout upsell apps (Requires sizing info, customizable thumbnail, true upsell with cart widget etc.) However what sets it apart is the speed of reply from customer support. I bother them a lot with custom requests but I have yet to wait more than 2 minutes to receive a human reply. Amazing!

Amazing! What a great customer services and dev team. I had some initial issues setting up the app but Santiago and team went above and beyond to understand my use case and help make it work. Oh, and the functionality is amazing, I needed something that could work with variants to trigger upsells, and this was really the only app hat I found that delivered, and more. Thanks Team UpsellPlus, 6-stars.

Super helpful App! Works very well and has helped us implement our upsell strategy with free gifts for purchases over a certain amount and upsell options. Support is great as well.

amazing support. really. no work for me almost

Couldn’t have been easier to set up! Their managed service and hands-on guidance make a world of difference – far beyond anything else we’ve tried.

We are having a great experience with UpsellPlus. It’s easy to use, and the upsells look clean and professional at the point of checkout. What really stands out is their customer service (shout out to Santiago and his team)—they respond quickly and always take care of any issues right away. The analytics clearly show it’s working, with a noticeable lift in our average order value. It’s made a real difference, and I’d definitely recommend it to anyone looking to boost sales. You'd be surprised at what a small nudge can do.

Nice tool & very good/fast support!

amazing! Santiago was so helpful. setting it up for e and even gave some cool suggestions for my site.

Excellent customer service

Genuinely fantastic and near-instant support, and the app absolutely works.

We’ve had a great experience using UpsellPlus to increase conversion and AOV strategy. We currently use their checkout and PDP upsell features, which integrate seamlessly with our store. The team especially Santiago has been responsive and proactive in providing performance insights and recommendations for new upsell opportunities. Their development support has been especially valuable, helping us customize features to fit our specific needs and brand experience. Overall, a reliable and collaborative partner for driving upsell performance.

The app has helped us to improve AOV and the team at Upsell are very supportive when trouble shooting any issues

Great experience so far. The Upsell team (Santiago) took care of the entire installation for me, and sent me updates while doing it. The best part of it: It was incredibly fast.

super buena atencion, de verdad te ayudan en todo y muy amables

Fantastic app and support!

Customer service is great, help me setup for my cart

This app served my needs perfectly. I was looking for a simple app to provide an add on item to my store and this is a great solution. The customer service was EXCEPTIONAL. Look no further. Santiago, you are a rock star!
