We've been using Rebuy for over a year, and it has been a reliable tool for driving personalized recommendations and improving the customer experience. The platform is feature-rich, easy to manage, and the support team has always been responsive and helpful. Overall, we've had a positive experience using Rebuy and appreciate the value it brought to our store.

Developer repliedThanks so much for the shoutout, we really appreciate it. Glad our support team has been hitting the mark for you 😊 Show more

Since implementing Rebuy, we've seen a meaningful lift in subscription adoption. The in-cart conversion tools have made it easy to turn one-time buyers into subscribers right at the moment they're most engaged, without adding friction to checkout. We've also seen stronger upsell and cross-sell performance across the site, helping customers discover more of what we offer in a way that feels relevant rather than pushy. Beyond the product itself, the Rebuy team has been an excellent partner. They're consistently responsive, hands-on when we're setting up new functionality, and quick to answer questions. It genuinely feels like they're invested in our success, not just running a support queue. If you're a Shopify brand looking to grow subscriptions, AOV, or overall revenue, I'd recommend Rebuy without hesitation.

Developer repliedReally glad the subscription and upsell tools are moving the needle for you, that's the whole point of building them into the cart experience. And honestly, hearing that the team feels invested rather than just ticket takers is the best kind of feedback we can get. Thanks for the shoutout 🙌 Show more

We’ve been longtime users of Rebuy, and our overall experience has been phenomenal. The team has consistently been communicative and proactive in sharing recommendations, introducing new features, and helping implement custom functionality. A special shoutout to our account manager, Maria Garcia, who has always gone the extra mile to support us with implementation and optimization. Since using Rebuy, our UPT increased by 10%, helping drive strong performance in H1 and contributing to a 12% lift in sales overall.

Developer repliedWow, a 10% UPT increase and 12% lift in sales speaks for itself, and Maria clearly deserves a ton of credit for that. Thank you for being a longtime partner, this is exactly the kind of impact we love seeing 🚀 Show more

So far, so good with this app. I will say the actual build process with Aiman was amazing. He makes everything very easy to follow. Has great knowledge of what he is doing. Very excited to see our conversion and AOV increase. It's a very robust tool, this actually eliminated 2 other expensive apps!

Developer repliedAiman is going to love hearing this, and honestly so are we. Replacing two expensive apps with one tool while boosting your conversion and AOV is exactly the win we build for 🚀 Show more

Our experience with Rebuy, and Aiman specifically, has been incredibly positive. From our initial enquiry, through development, and implementation, Aiman ensured that he had a thorough understanding of our business needs, and that we were fully conversant with the options available. The whole process ran smoothly, from start to finish, and now we look forward to seeing the positive impact of what will become an invaluable tool.

Developer repliedThis is exactly the kind of partnership we aim for from day one. So happy it came together smoothly and we're excited to see it pay off for you 🚀 Show more

Rebuy is a great app with lots of functionality. Our CSM Maria is an especially bright spot that helps us ship so many features. We have been using Rebuy at my company for 4 years and Maria is the best CSM we have had. She is top notch.

Developer repliedFour years and counting means a lot to us, and we love hearing that Maria has been such a big part of that 🌟 She's the real deal and we'll make sure she sees this. Give us a shout if you ever need anything! Show more

Rebuy has been a great tool for helping us create bundles and improve our customer experience. The app is easy to use, flexible, and works really well for our needs. Aiman was also a huge help and incredibly fast with our customization requests. Highly recommend!

Developer repliedAiman is a rockstar so this tracks completely 😄 Really glad the bundles are working well for you, and we'll be here whenever you need us next. Show more

I rarely leave negative reviews, but after our experience I feel other merchants should be aware of the risks. A deployment made by Rebuy caused a critical issue on our Shopify store which prevented customers from accessing and using the cart. The issue effectively stopped customers from completing purchases and had a significant impact on our trading until it was identified and rolled back. To Rebuy's credit, their support team eventually acknowledged that the issue was related to an update released from their side and subsequently reverted the change. However, the incident should never have happened in the first place, particularly given that Rebuy was not even responsible for our cart functionality. What has been equally disappointing is the handling of the matter afterwards. The outage escalated internally to Board level due to the commercial impact on our business, yet resolving the issue required repeated chasing, long delays between responses, and multiple escalations to senior management. After weeks of discussions regarding compensation, Rebuy ultimately agreed to release us from our 36-month contract but offered no financial compensation for the disruption caused by an outage that they themselves acknowledged originated from a Rebuy deployment. The platform itself may work well for some merchants, but our experience exposed a concerning level of operational risk. Any third-party app capable of interfering with core checkout journeys should be subject to extremely rigorous testing before updates are pushed live. Based on our experience, I would urge merchants to carefully consider both the technical risks and the level of accountability they can expect if something goes wrong.

Developer repliedThank you for sharing your experience. We take feedback like this seriously and are sorry to hear this fell short of the standard we aim to provide. We appreciate you taking the time to leave this review and hope to have the opportunity to restore your confidence in us. Show more
