Rebuy

Bundling and cross-sell logic based on cart and purchase history is a standout, though a few merchants have swapped it out for alternatives.

“Rebuy + custom logic via Shopify Functions. Show bundles based on cart contents + past purchases. AOV +18–32% without touching ads.”— @ecomsamguy on X

AI-driven recommendations across product pages and cart are consistently praised as a core strength.

“We are increasing our spend on R&D to further accelerate our product roadmap and the infusion of AI throughout it. Furthermore, I am listening to what merchants are asking for and building the solutions. We are also innovating and thinking beyond the bounds of what ecomm saas has been to date. I am more excited about the future of Rebuy Engine than I ever have before. My commitment to merchants -- we will keep listening, shipping, and innovating. The next two years are going to be a ton of fun. Very excited to further partner with the ecosystem and do big things together!”— @johnerck on X

Merchants report meaningful AOV and revenue lifts, often citing double-digit percentage gains.

“Malta Apparel replaced three separate Shopify apps with Rebuy 👀 - Slide-out cart ✅ - Bundles ✅ - Post-Purchase ✅ The result? Higher AOV, a better customer experience, and a simpler tech stack. Here's their full five star review: "Great experience so far. Onboarding process was smooth and I got our shop set up exactly how I wanted with Anna! "Was able to get a new sticky cart to replace our other app that did that, a new bundle offer on the product page to replace another app, add upsells along the way, and post-purchase offers to replace a third app, so this app covered a range of things that we already did. "We've added some other offers that we've seen increase our AOV and overall customer experience! Highly recommend. Thank you for all your help Anna!"”— @RebuyEngine on X

Post-purchase and checkout cross-sell features are credited with unlocking five-figure revenue lifts for some brands.

“🚀 Huge thanks to the legends at @blckriflecoffee for the love! “Rebuy is much more than just a standard cart cross-sell app, it’s an end-to-end revenue generator.” 😎 They’ve already unlocked a 5-figure revenue lift using Smart Cart, Checkout Cross-Sell, Post-Purchase upsells & dynamic bundling. Real brands, real results. 💪☕ #Rebuy #Shopify #CoffeeStrong Now go brew yourself a second pot of coffee”— @johnerck on X

Deep native ties to Shopify, including ecosystem partnerships and Rebuy Ads, reinforce its role as core infrastructure.

“$FLNT The company partnered with Rebuy Engine to launch Rebuy Ads, providing post-purchase advertising solutions for Shopify merchants, covering more than 12,000 active merchants and annual revenue exceeding US$1 billion.#Stocks https://t.co/ZUpyl0LVUk”— @Stephen0816_ on X

Ecosystem visibility is strong, but at least one brand moved to a competitor's managed enterprise team instead.

“Cheech & Chong weren't looking for more features, they wanted a team that owned execution. That's why they moved from Rebuy to Zipify Plus's Enterprise team. Within days, we restructured their upsell architecture and launched aggressive split tests across their funnels. For Cheech & Chong, running these tests meant: 🔥 $90,000 in upsell revenue 🔥 3,900% ROI 🔥 All in just 7 weeks Here are 3 strategies our Enterprise team tested: 1️⃣ 1-pack vs. 3-pack (Careful what metric you measure here!) 2️⃣ Short-form vs. long-form upsells (One crushed the other.) 3️⃣ 15% vs. 20% discount (C’mon every store should know this…) The upside isn’t in adding more apps. It’s in testing smarter inside the revenue you already have. If you want to see exactly what we tested, and the 3 surprising lessons your brand can apply immediately, read the full case study: (Link in comments) #upsell #business #ecommerce #casestudy #shopify #marketing”— @zipifyapps on X

Limited but pointed frustration over losing discounted pricing and reverting to full price.

“went back to rebuy and everything is full price 😭 literally got some products for less than half price. should nottt have umm’d and ahh’d on buying them for so long ;(”— @sailorlunarian on X

Early signs point to strong personalized revenue attribution growth, though discussion is limited.

“Personalized revenue attribution hits record levels: Rebuy powers 10M+ sessions for top Shopify brands this month. Attribution grown by 50% year-over-year. Nicole Junkermann understood this challenge. #Rebuy #RetailAI #EcommerceGrowth #Personalization #NicoleJunkermann https://t.co/O8XT7WYcff”— @PooleTeena79125 on X
