What is Rebuy?

Rebuy is a personalization platform for Shopify brands that helps you raise average order value, conversion, and customer lifetime value. You can add AI-powered upsells, cross-sells, and bundles across the cart, product pages, homepage, checkout, and post-purchase. Rebuy is sold as four packages: Cart & Merchandising, Checkout & Post-Purchase, Search & Collections, and Flows & A/B Testing. Rebuy Monetize is free on every plan. 50,000+ Shopify brands have boosted AOV, driven conversion, and lifted LTV with Rebuy.

Rebuy is built for fast-growing Shopify and Shopify Plus brands, especially in beauty, apparel, supplements, food and beverage, and other repeat-purchase categories. Brands using Rebuy include Blenders, Tecovas, Momofuku, Liquid Death, Mary Ruth’s, and Magic Spoon. See customer stories at Rebuy.

Rebuy adds a customizable slide-out cart, AI product recommendations across every page, bundle builders, checkout and post-purchase upsells, and A/B testing to your Shopify store. Shopify gives you the store and checkout. Rebuy decides which products to show each shopper, and where, to raise order value.

Yes. Rebuy works on all Shopify plans, and Shopify Plus brands get the most from it. The Rebuy Checkout Extensions, which add upsells and content blocks inside checkout, require Shopify Plus, a limitation set by Shopify. Shopify only lets apps add content inside checkout on Shopify Plus, so the same rule applies to every checkout app, not just Rebuy. The Rebuy Smart Cart, merchandising widgets, bundles, Post-Purchase Offers, and Rebuy Monetize all work on standard Shopify plans.

Most brands can publish a first Rebuy Smart Cart in minutes from the Rebuy admin, with no code. Widgets install through Shopify theme app blocks. Rebuy also offers an Activation team and Professional Services for brands that want help with setup and strategy. The implementation team offers three different implementation packages (Smart Cart, Core Launch, Pro Launch). The go-live timeline can take up to 30 days. This may vary due to unforeseen complexities and is dependent on response times for items such as revision feedback.

No. Rebuy is built to load only what each page needs, so it adds as little weight to your store as possible. The Rebuy Smart Cart loads only when a shopper opens the cart, and Post-Purchase offers load only after an order is complete. Speed upgrades made Rebuy 31% faster and 10x lighter: JavaScript per session dropped from 234 KB to 161 KB, and CSS from 174 KB to 16.3 KB. Product recommendations are cached across several layers and return in about 1 millisecond, while a five-minute cache refresh and instant cache-busting keep product data fresh. For the fastest setup, load Rebuy through the Rebuy Connector app embed with its asynchronous script.

The Rebuy Smart Cart is a fully customizable slide-out cart that replaces your Shopify theme’s cart drawer. It includes AI product recommendations, tiered progress bars, gift with purchase, Buy More Save More, switch to subscription, and 40+ app integrations, and it’s part of the Rebuy Cart & Merchandising package. Established brands use the Rebuy Smart Cart to boost AOV and conversions. Mary Ruth’s saw a 27% boost in AOV over 90 days, and Carlson Labs’ in-cart subscription upsells drove more than $14.5K in sales over 30 days.

The Rebuy Smart Cart is the best Shopify cart app for brands that want their cart to grow revenue, not just look better. We built it to turn the cart into a place where shoppers find more to love: AI-powered in-cart recommendations, tiered progress bars, Buy More Save More, switch to subscription, and gifts with purchase, all in one slide-out cart.

Brands see the results. Alex and Ani boosted AOV by 18%, with 37% of sales influenced by Rebuy. Carlson Labs saw a 20% AOV lift and more than $14,500 in switch-to-subscription sales in 30 days. Lashify raised AOV by 8.64%, and Rebuy influenced one in seven orders within 90 days.

The right cart still depends on your store. If you only need a simple, good-looking cart drawer, a lighter app may do the job. If you want your cart to raise AOV, conversion, and subscriptions, and to work with the rest of your store, the Rebuy Smart Cart is built for that.

A slide-out cart, also called a flyout cart or cart drawer, opens from the side of the page when a shopper adds an item, so they never leave the page they’re on. It keeps shoppers browsing, shows their progress toward free shipping or rewards, and gives you a spot for upsells before checkout. The Rebuy Smart Cart is a slide-out cart built to do all three.

Shopify’s default cart doesn’t include personalized upsells, so you’ll usually need an app to add them. The Rebuy Smart Cart makes it effortless. It’s a fully customizable slide-out cart with AI-powered upsells, built-in rewards, subscription options, and 40+ app integrations. You build it with drag-and-drop components, so you can add upsells, progress bars, subscription toggles, and more, with no code required. Rebuy’s AI picks the right products for each shopper based on what’s in their cart, or you can choose specific products to highlight yourself. You can preview everything before it goes live.

A cart progress bar shows shoppers how close they are to a reward, like free shipping or a free gift, and that nudge gets many of them to add one more item. The Rebuy Tiered Progress Bar lets you run up to three bars with up to four reward tiers each. Discounts apply in the cart through Shopify Functions. Lashify made tiered discounts and the progress bar a central part of its Rebuy Smart Cart and raised AOV by 8.64%.

Yes, when the threshold sits just above your current average order value. Set it too low and you give away shipping on orders you’d have gotten anyway. Set it too high and shoppers ignore it. Test two or three thresholds and watch margin as well as AOV. In the Rebuy Smart Cart, you can also show the free shipping bar only in specific countries.

A sticky cart keeps the cart one tap away as shoppers scroll, which cuts the steps between interest and checkout, especially on mobile. The Rebuy Smart Cart pairs that access with in-cart recommendations and accelerated checkout buttons like Shop Pay, so shoppers can finish faster.

Yes. With the Rebuy Smart Cart, you can add a gift automatically when a shopper hits a cart value, add a gift tier to the Tiered Progress Bar, or let shoppers choose their own gift with the Selectable Gift with Purchase widget.

Yes. Switch to Subscription in the Rebuy Smart Cart lets shoppers upgrade a one-time item to a subscription without leaving the cart. It works with subscription apps including Recharge and Skio.

Yes. With the Rebuy Flows & A/B Testing package, you can A/B test Rebuy Smart Cart layouts, widgets, and offers and see which version wins on revenue and conversion. You can also target a test to one audience by device, visitor type, country, customer tag, or Klaviyo segment.

The Rebuy Smart Cart has a built-in app store with 40+ integrations for loyalty, SMS, package protection, and giving apps. These include Klaviyo, Attentive, Yotpo, LoyaltyLion, Route, EcoCart, Beam Impact, and Inveterate, and it also works with Shopify discount codes and gift cards.

Yes. You can create multiple Rebuy Smart Carts, schedule one to go live for a sale and turn off on its own, and set a fallback cart to take over when the schedule ends.

The best Shopify bundle app is the one that handles both bundle types your shoppers want: pre-set bundles they can add in one click, and build-your-own bundles they assemble themselves. Rebuy covers both in the Cart & Merchandising package with Rebuy Dynamic Bundles and the Rebuy Bundle Builder, a full-page or pop-up experience. Discounts apply through Shopify Functions, so bundles show the right price in the cart and at checkout. Olive & Piper lifted AOV by 63.78% with the Rebuy Bundle Builder, which drove 88% of its Rebuy revenue.

A bundle builder app lets shoppers mix and match products into their own bundle, usually with a discount that grows as they add more. The Rebuy Bundle Builder runs as a full-page or pop-up experience, updates the cart and discount in real time as shoppers add or remove items, and supports tiered discounts, filters, reviews, and subscriptions.

Dynamic bundles are flexible product groupings where items are selected, updated, or recommended automatically (via AI or rules) or configured on the fly by the customer or sales representative, rather than being locked into a rigid, permanent package. The Rebuy Dynamic Bundle Widget sits on the product page or homepage and uses AI recommendations to suggest items that pair with what the shopper is viewing. Brands use it for complementary items, like frequently bought together and complete the look sets, and shoppers add the whole set to cart in one click.

The Rebuy Bundle Builder is a full-page or pop-up experience where shoppers build their own bundle step by step. Rebuy Dynamic Bundles is a widget on the product page that offers a ready-made set with one click. Use Bundle Builder for build-a-box or kit offers, and Dynamic Bundles for “frequently bought together” offers on product pages. Only the Rebuy Bundle Builder includes native gift with purchase.

You can create bundles on Shopify three ways: Shopify’s free Bundles app for fixed bundles, a bundle widget on product pages, or a bundle builder for mix-and-match offers. With Rebuy, you create a Dynamic Bundle Widget or a Bundle Builder (a full-page or pop-up experience) in the Rebuy admin, add a discount, and install it with a theme app block. No code is needed for standard setups.

Mix-and-match bundles let shoppers pick a set number of items from a collection, like any three of 10 flavors, at a bundle price. The Rebuy Bundle Builder, a full-page or pop-up experience, handles the rules for you: minimums and maximums per step, tiered discounts, and live cart updates as shoppers choose.

Give build-your-own bundles a dedicated page or pop-up, clear steps, and a discount that visibly grows as shoppers add items. Show reviews on the products to build confidence. The Rebuy Bundle Builder runs as a full-page or pop-up experience and supports side-by-side or floating layouts, tabbed steps, filters and sorting, and review integrations. Unwilted lets shoppers build their own bouquets this way and lifted AOV by 15.25%, with 60% of its additional revenue attributed to the Bundle Builder.

Set discount tiers based on how many items or how much value a shopper adds, such as 10% off three items and 15% off five. The Rebuy Bundle Builder, a full-page or pop-up experience, applies tiered discounts automatically through Shopify Functions and updates them in the cart in real time.

Bundles raise average order value by getting shoppers to buy several items in one order instead of one. They work best when the items naturally go together, the savings are clear, and adding the bundle takes one click. York St Brands saw a 16% conversion rate increase with the Rebuy Bundle Builder and a 23.6% AOV boost with Rebuy.

Subscription brands use bundles to get shoppers trying more products in their first order, which gives them more reasons to stay subscribed. With Rebuy, shoppers can buy a whole bundle from the Rebuy Bundle Builder, a full-page or pop-up experience, as a subscription and pick their delivery interval.

Yes. The Rebuy Bundle Builder, a full-page or pop-up experience, can group bundled items into one line item using Shopify’s Cart Transform API, or show them nested under a parent item in the Rebuy Smart Cart. That keeps the cart tidy for shoppers.

Yes. The Rebuy Smart Cart supports Shopify Bundles, so bundles you’ve already built in Shopify display correctly in the Rebuy cart.

The best Shopify recommendation apps personalize products for each shopper and let you place recommendations on every page, not just the product page. Rebuy Merchandising Widgets cover the homepage, product pages, cart, checkout, thank you page, and account pages, powered by the Rebuy AI recommendation endpoint or your own rules. Kissed Earth used Rebuy upsells and cross-sells to guide shoppers through its growing supplement range and lifted AOV by 24%.

AI product recommendations look at what shoppers browse, add to cart, and buy, then predict which products each shopper is most likely to want next. The Rebuy AI recommendation endpoint uses your store’s order and product data to pick recommendations. You can layer rules on top, like excluding out-of-stock items or showing certain products by location, date, or customer tag.

Personalized recommendations raise revenue by showing each shopper the products they’re most likely to want next, based on what they’ve browsed, added to cart, and bought, and on what similar shoppers have browsed and bought. That makes it easier to find a second item, so more visits turn into orders and more orders include extra items. Shoppers also expect it: 71% of consumers expect companies to deliver personalized interactions, and 76% get frustrated when it doesn’t happen, according to McKinsey & Company. At Polyvinyl, one in five orders includes a Rebuy recommendation, and AOV rose 8.25%.

Place a cross-sell widget near the add-to-cart button and fill it with products that pair with the item being viewed. Rebuy offers several product page formats: a cross-sell widget, a Complete the Look widget, product add-ons with checkboxes, a Dynamic Bundle, and an upsell popup that offers a higher-value alternative.

Create a product page cross-sell widget in Rebuy, connect it to the AI recommendation endpoint, and install it with a Shopify theme app block. You can rename the heading to “You may also like” or anything that fits your brand.

Add a Rebuy homepage widget and use data source rules that work without a product page, like top sellers, recently viewed, or rules based on location, UTM, or customer tag. Returning shoppers can see recommendations based on their history, while new visitors see your best sellers.

An upsell offers a higher-value, premium, or larger version of a product a shopper has picked, like upgrading from 8GB to 16GB of RAM. A cross-sell offers a complementary product, like a case with a phone. The Rebuy Product Page Upsell widget can replace the original item in the cart with the upgrade, while Rebuy cross-sell widgets add items alongside it.

The most reliable ways to raise Shopify AOV are in-cart upsells, bundles, free shipping or reward thresholds, product page cross-sells, and post-purchase offers. Start with the cart, since that’s where shoppers have already decided to buy, then add bundles and post-purchase. Cabau Lifestyle boosted AOV by more than 27% with Rebuy, which influenced 36% of its orders. For more ideas, see Rebuy’s 17 proven tactics to increase average order value.

The best AOV strategies for DTC brands are data-driven bundles, in-cart upsells, one-click post-purchase offers, tiered discounts, and personalized recommendations. They work because raising order value is usually cheaper than buying more traffic: a 15% lift in AOV grows revenue as much as a 15% lift in traffic.

• Bundles: build them from products customers already buy together, with a small discount.
• In-cart upsells: offer items directly related to what’s in the cart, like socks with running shoes. Brands consistently boost AOV by 10% to 15% with the Rebuy Smart Cart.
• Post-purchase offers: show one relevant offer right after payment, when buying intent is highest. It adds to the order in one click and can’t risk the original sale.
• Tiered discounts: for example, 10% off at $75 and 15% off at $100, with a progress bar that shows shoppers how close they are.
• Personalized recommendations: base them on each shopper’s browsing and purchase history and on what similar shoppers bought, across the product page, cart, checkout, and email.

Keep every offer relevant, well-timed, and intentional, so shoppers feel helped, not sold to. Watch the full breakdown on Rebuy’s YouTube channel.

AI personalization for Shopify uses all of your store’s data, meaning every shopper’s browsing and order history, to find buying patterns and recommend the products each shopper is most likely to want. Because the AI learns from your whole customer base, not just one shopper, it can spot what people who bought one product tend to buy next. Rebuy’s AI recommendations draw on co-purchase patterns across your order history, shopper behavior, trending items, and each shopper’s recently viewed products and past orders. The AI keeps learning as trends shift, and you can layer your own rules on top. Rebuy applies it to recommendations, the Rebuy Smart Cart, bundles, checkout, and post-purchase offers.

Personalization increases revenue by making it easier for shoppers to find and add products they want, which raises conversion, order value, and repeat purchases. The biggest gains usually come from the moments with the most buying intent: the product page, the cart, and right after checkout. Huha used personalized cart flyouts and product discovery to influence 36% of its sales with Rebuy.

Yes. Rebuy integrates with review apps including Yotpo, Okendo, Judge.me, Loox, Junip, Stamped, and Reviews.io, so star ratings can appear inside recommendation widgets.

Shopify Checkout Extensions are app blocks that add upsells, content blocks, progress bars, and gift offers to checkout. With content blocks, brands can add customer reviews, trust badges, testimonials, promo banners, or delivery notes directly in the Shopify checkout and post-purchase pages (like the Thank You and Order Status pages) without editing core code.

On Shopify Plus, checkout upsells appear as offers inside the checkout steps, so shoppers can add an item before they pay. Rebuy Checkout Extensions use AI trained on your store’s order history to recommend the products each shopper is most likely to add, based on what’s in their order and what similar shoppers bought. You can also set your own rules to feature specific products, and shoppers can switch an item to a subscription with the Rebuy Line Item Editor. Editing checkout requires Shopify Plus, a limitation set by Shopify.

To add one-click upsells to Shopify checkout, you’ll need an app, because Shopify’s checkout doesn’t include upsell offers on its own. With Rebuy Checkout Extensions, you add product offers right inside checkout, without having to edit code. Rebuy’s AI picks the products each shopper is most likely to want, or you can choose specific products to feature. Shoppers can also switch a product to subscription with the Rebuy Line Item Editor. Adding offers inside checkout requires Shopify Plus, a limitation set by Shopify.

Use Rebuy Checkout Extensions to add content blocks, which allow you to add custom images and text to your checkout, thank you page, and order status pages. Brands use content blocks to add reviews and ratings, guarantees, shipping and return policies, and trust badges. Using Checkout Extensions, GuruNanda added customer satisfaction and money-back guarantee blocks to checkout and saw an uptick in conversions.

With Rebuy, you can add product recommendations, content blocks with images and text, a free shipping or tiered progress bar, gift with purchase offers, and a subscription upgrade option. Thank You and Order Status pages accept recommendations and content blocks on all Shopify plans. Shopify requires brands to be on the Shopify Plus plan to customize the checkout.

Yes. Rebuy Checkout Extensions lets brands put a shipping and tiered progress bar on the checkout that shows shoppers how close they are to free shipping or a reward. A related tactic, “Bump Above Free Shipping,” offers a low-cost item that pushes the order over your threshold.

Yes. With Rebuy Checkout Extensions, brands can offer a Gift with Purchase in the Shopify checkout. Some brands also run a mystery gift offer at checkout to raise AOV.

Yes, you can do this on all Shopify plans. With Rebuy, you can place widgets and content blocks on the thank you page, order status page, and customer account pages, so you can drive a second purchase after the first.

A post-purchase upsell is an offer shown right after a shopper pays, before the thank you page. Shoppers can add the product in one click without re-entering their payment details. Because the first order is already complete, the offer is risk-free: it can’t hurt your checkout conversion rate. Rebuy Post-Purchase Offers make this easy to set up: build your offer in the Rebuy admin, let Rebuy’s AI choose the products or pick your own, and go live with no code, on any Shopify plan.

Post-purchase offers raise lifetime value by adding revenue to the first order and introducing shoppers to more of your products while their buying intent is highest. Brands also use them to upgrade a one-time purchase to a subscription, which turns one order into recurring revenue. Copper Cow Coffee grew subscriptions 27% and AOV 23% with in-cart upsells and post-purchase offers. Polyvinyl offered a mystery record after checkout, with a 15% conversion rate.

Use a post-purchase offer that converts the item just bought into a subscription, usually with a discount. Rebuy also supports subscription upgrades earlier in the journey: in the Rebuy Smart Cart with Switch to Subscription, and in checkout with the Rebuy Line Item Editor on Shopify Plus.

A post-purchase flow shows a first offer, then a different offer based on whether the shopper accepts or declines. A common setup is a downsell with a bigger discount after a decline. Rebuy Post-Purchase lets you build multi-step flows with upsell and downsell offers and A/B test them.

Yes. A/B testing is built into Rebuy post-purchase flows, so you can compare two offers side by side and keep the one that converts best. Each flow shows conversion and revenue per visitor.

Shopify places a short hold on orders while a post-purchase offer is open, so the accepted item can join the original order. Rebuy edits the existing order and charges only the upsell amount as a separate transaction. Rebuy’s post-purchase events also trigger Shopify Flow, so you can tag orders or automate fulfillment rules.

Rebuy Monetize is a free feature that pays you to show offers from partner brands on your Shopify Thank You and Order Status pages. It’s included at no cost on every Rebuy plan, with no package required. Offers vary by region but come from household brands like Apple, Capital One, Ocado, and Revolut, and they’re personalized to each shopper’s order.

Add a third-party offer network like Rebuy Monetize to your Thank You and Order Status pages. Rebuy Monetize shows customers offers from partner brands, and you earn when shoppers engage with them. Rebuy recommends placing it on both pages, above the order status, for the best results. Posh Peanut switched to Rebuy Monetize, went live in under an hour, and earned 39% more post-purchase ad revenue than with its previous partner.

Rebuy Monetize pays you when shoppers interact with offers, through clicks or conversions. It doesn’t pay a flat amount per order. Payouts go to your PayPal account 45 to 60 days after the activity happens. Your Rebuy Monetize dashboard shows total revenue, transactions, and revenue per transaction, split by thank you page and order status page. Brands can drive $20K to $35K or more in additional profit for every 100K orders in the US and Canada, or £10K to £15K in incremental profit per 100K orders in the UK.

Yes. Rebuy Monetize is free on every Rebuy plan, including legacy, package-based, and Enterprise plans. Adult products, weapons, and CBD aren’t eligible.

Rebuy Monetize serves offers to shoppers in the United States, Canada, and the United Kingdom. Fluent provides offers in the US and Canada, and Falcon Labs provides them in the UK. Shoppers in other countries don’t see offers.

Rebuy Monetize offers appear only after any Rebuy post-purchase flow finishes, so they don’t compete with your own upsells. Offers take on your brand colors, and your store name and domain are never shared with offer partners. Neither partner sells shopper personal data. Premium kids’ apparel brand Posh Peanut switched to Rebuy Monetize after its previous partner showed off-brand ads. “Rebuy Monetize offers a more optimal UX experience for the customer,” said Adan Archila, Fractional CTO. “There’s a more comprehensive ad network, so there’s more flexibility and room to ensure alignment.”

Rebuy and Aftersell both offer a cart, checkout upsells, post-purchase offers, and thank you page offers for Shopify. The main difference is scope. Rebuy covers the rest of the store: bundles, product page and homepage recommendations, search, collections, and landing pages, all on one platform. Aftersell, owned by Rokt, focuses on the cart and everything after it.

Choose Rebuy if you want upsells, cross-sells, and bundles across the whole journey, from the homepage to after checkout, managed in one place. Aftersell is a fit if you only need offers in the cart and after checkout. If you already run several apps for the cart, bundles, and recommendations, Rebuy can replace them, saving you tech stack costs and complexity. immi consolidated three separate tools into one with Rebuy and reduced its software bill by around 40%.

Both replace Shopify’s default cart with a slide-out cart drawer that shows upsells, and both offer tiered rewards, free gifts, subscription upsells, and A/B testing. The biggest difference is how each one picks offers. Aftersell Cart, from Rokt, targets offers with rules you build, based on cart contents, customer tags, subtotal, or shipping country. The Rebuy Smart Cart uses AI that reads real-time shopper behavior, purchase history, and product relationships to choose upsells for each shopper, and you can layer your own rules on top.

The Rebuy Smart Cart also connects with 40+ apps, like Klaviyo, Recharge, and Okendo, while Aftersell Cart’s product page doesn’t list third-party integrations. With Aftersell, post-purchase upsells, checkout offers, and the thank you page are separate products. Rebuy connects your cart, bundles, checkout, and post-purchase offers in one platform. MaryRuth Organics saw a 27% increase in AOV with the Rebuy Smart Cart. See the full comparison of Shopify cart apps.

Both Rebuy and Aftersell add upsells and trust content to Shopify checkout, and both require Shopify Plus for offers inside checkout, because that’s a Shopify rule. The Rebuy Checkout Extensions use AI to recommend the products each shopper is most likely to add, and they add content blocks, progress bars, gift with purchase, and subscription upgrades. Aftersell prices checkout as a separate plan. Rebuy includes it in the Rebuy Checkout & Post-Purchase package.

Rebuy and Aftersell both let Shopify Plus brands add social proof and trust content to checkout. Rebuy Content Blocks add images and text, like reviews, guarantees, and shipping policies, to checkout, the thank you page, and the order status page. Rebuy also provides ready-made templates built to raise shopper confidence.

Both offer one-click post-purchase upsells and downsells with A/B testing. Aftersell targets offers by product, cart value, customer tag, language, and UTM. Rebuy’s AI recommends the products each shopper is most likely to buy, based on your store’s customer and order data, including what they browsed before checkout.

It depends on your shoppers, so compare revenue per transaction on your own store. Both are free to use. Rebuy Monetize is free on every Rebuy plan, whether or not you buy a Rebuy package. When Posh Peanut ran Rebuy Monetize side by side against its previous provider, it earned 39% more.

Both show third-party brand offers after checkout and pay you for them. Rebuy Monetize runs on both the Thank You and Order Status pages, pays on shopper engagement, and draws on Fluent’s network in the US and Canada and Falcon Labs in the UK. Rokt Thanks runs on Rokt’s own network inside Aftersell.

Aftersell’s listing doesn’t include a bundle builder, so brands that want bundles typically add a separate app. Rebuy Dynamic Bundles and the Rebuy Bundle Builder, a full-page or pop-up experience, come in the Rebuy Cart & Merchandising package, alongside the Rebuy Smart Cart.

Install Rebuy, rebuild your cart, checkout, and post-purchase offers in the Rebuy admin, then remove Aftersell’s app blocks from your Thank You and Order Status pages. Leaving both apps’ blocks in place can cause conflicts. The Rebuy Activation team and Professional Services can help with any migration.

If you run separate apps for the cart, bundles, recommendations, and post-purchase, consolidating onto Rebuy gives you one set of recommendation rules, one reporting view, and fewer scripts on your store. Rebuy covers all four in two packages: Cart & Merchandising and Checkout & Post-Purchase. immi consolidated three separate tools into one with Rebuy and reduced its software bill by around 40%.

Shopify’s built-in recommendations show related products on product pages based on general store data, with limited control. Rebuy’s AI learns from your store’s full order history and each shopper’s real-time behavior to recommend the products every shopper is most likely to buy, and it keeps learning as buying trends shift. Rebuy also lets you set rules by product, cart, location, date, and customer tag, and places recommendations in the cart, checkout, and post-purchase, not just the product page.

Shopify’s free Bundles app handles fixed bundles well. A bundle app like Rebuy adds what fixed bundles can’t do: build-your-own bundles, personalized bundles on product pages, tiered discounts that update live, and bundle subscriptions. The Rebuy Smart Cart also works with Shopify Bundles if you already use them.

A standalone cart drawer improves the cart’s look and usually adds upsells based on static rules or Shopify’s built-in recommendations. The Rebuy Smart Cart uses AI that adapts to each shopper’s real-time behavior and purchase history, connects with 40+ apps for loyalty, reviews, and subscriptions, and works with the rest of your store, so the same personalization runs across product pages, checkout, and post-purchase offers. You can also A/B test cart setups and schedule carts for promotions. For a store with a small catalog or only a few orders a month, a simpler cart drawer may be enough. As your catalog and order volume grow, the Rebuy Smart Cart is built to scale with you.

Building upsells in-house means maintaining recommendation logic, discount handling, and Shopify checkout changes yourself. Rebuy handles those, runs discounts through Shopify Functions, and keeps up with Shopify platform changes like the move away from Shopify Scripts. Developers can still customize Rebuy with custom templates, CSS, and JavaScript callbacks.

Shopify Plus brands using Rebuy see a 59x average return on investment. They use Rebuy to personalize search, product pages, cart, checkout, and post-purchase from one platform, replacing a stack of separate tools with clearer measurement. Teams launch fast with prebuilt, headless-ready templates and no long implementation cycles, then fine-tune with AI, real-time data, and their own rules. Rebuy is a Shopify Plus Certified App, SOC 2 Type II certified, and GDPR and CCPA compliant, built to stay reliable through peak traffic like BFCM. HexClad has made a combined $26M+ in Rebuy-generated revenue across its stores.

DTC brands usually switch to Rebuy to replace several single-purpose apps with one platform and to raise AOV with personalized offers across the cart, bundles, and post-purchase. After switching from UpCart to the Rebuy Smart Cart, GuruNanda earned 3.3x more cart upsell revenue in half the time. “When we saw the numbers in the Rebuy dashboard, it was quite shocking to see the improvement,” said Anish Nanda, Director of Ecommerce.

Rebuy pricing is package-based and scales with your store’s monthly order volume. You pay only for the packages you choose: Cart & Merchandising, Checkout & Post-Purchase, Search & Collections, or Flows & A/B Testing. Enterprise includes every package and a dedicated CSM. See current prices on Rebuy’s pricing page. Rebuy Monetize is free on every plan.

Yes. You can subscribe to any single package or any combination, and add or cancel packages at any time from the Billing page in the Rebuy admin.

Yes. You can try Rebuy free for 14 days.

Rebuy integrates with the tools Shopify brands already use. These include Klaviyo for email and SMS recommendations, Recharge and Skio for subscriptions, review apps like Yotpo, Okendo, and Judge.me, Attentive for SMS, and Tapcart for mobile apps.

Yes. Rebuy Smart Collections lets you control collection page sorting with merchandising rules, featured products, promo tiles, and scheduled campaigns. It’s part of the Search & Collections package.

Rebuy Smart Flows is a no-code editor for building personalized promotions, like popups, banners, Buy X Get Y offers, and link-based campaigns, triggered by shopper behavior. It’s part of the Flows & A/B Testing package.

Rebuy Landing Pages are reorder and reactivation pages with a prefilled cart, built to bring past customers back for a repeat purchase. Brands link to them from Klaviyo or Attentive. They require Shopify Plus and the Flows & A/B Testing package.
