Compare the 10 best Shopify bundle apps for 2026 by bundle type, pricing, inventory sync, and Shopify Plus fit, from free plans to personalized bundles.
Bundles are the oldest trick in the book.
The value meal. The gift set. The 24 pack of socks when you only meant to buy one pair (we've all been there).
They work because shoppers love a deal and merchants love a bigger cart. On Shopify, the right bundle app turns that old trick into a higher average order value without a spreadsheet, a pile of discount codes, or a weekend lost to manual inventory updates.
The hard part is picking one. Search "bundles" in the Shopify App Store and you'll get more than 4,000 results.
So we compared the 10 best Shopify bundle apps on the things that matter once a bundle goes live: bundle types, pricing, inventory sync, checkout compatibility, and fit for stores from first sale to Shopify Plus.
Quick disclosure: Rebuy Dynamic Bundles (our one-click add to cart bundles) and the Rebuy Bundle Builder (our build-your-own bundles) compete with most of these apps. You'll find Rebuy at number one (shocking, we know). So read our list with that in mind. We've tried to give every app a fair shake, cons included. Ours too.
Prices and features come from each app's Shopify App Store listing in October 2026. They change, so check the listing before you install.
A product bundle groups two or more products into one offer, usually at a discount (our bundles glossary entry has the longer definition.)
Here's why Shopify brands use them:
Before you compare apps, know which bundle type you want. Most apps are great at two or three of these and fine at the rest.
Star ratings only tell part of the story, so here are the eight criteria we used to rank these apps, and the ones we'd use to judge any bundle app:
Most bundle apps live on the product page. Rebuy bundles are part of the Rebuy Cart & Merchandising package, next to the Rebuy Smart Cart and merchandising widgets. That means the same AI-powered product recommendations can power bundles on product pages, the homepage, the cart, checkout, and post-purchase.
You get two bundle tools.
Rebuy Dynamic Bundles use AI and a rules engine to build frequently bought together bundles from browsing and purchase history. No manual updates required. Shoppers can pick variants like size or flavor, remove items they don't want, and add the whole bundle to cart in one click. Merchants can also choose which products they want bundled together if they'd like to curate their bundles.
The Rebuy Bundle Builder is a guided, multi-step build-your-own bundle experience with a progress bar and a built-in gift with purchase. Run it as a full bundle-builder page, on a product page, or as a pop-up (our launch team can help set that up for you).

Pricing: Cart & Merchandising starts as low as $25/month for one package. Pricing is based on monthly orders, not revenue. Every package comes with a 14-day free trial, a positive ROI guarantee, and 10% off with annual billing. See Rebuy pricing.
Pros:
Cons:
Simple Bundles & Kits is the pick when your warehouse matters as much as your storefront. It offers single and multi-SKU inventory sync across 3PL, WMS, ERP, and fulfillment tools, and it breaks bundle orders down into components so the right items get packed.
Key features:
Pricing: Free for up to three bundles and 50 monthly orders. Basic is $24/month ($14/month for stores under 100 monthly orders). Grow & Advanced is $39/month. Plus is $149/month and adds a dedicated order processing queue and headless support. Annual billing saves 17%.
Pros: Excellent component-level inventory tracking, strong 3PL and ERP support, and a real Plus plan.

Key features:
Pricing: Free on development stores. Live stores pay $19/month for up to $1,000 in monthly bundle sales, $49/month for up to $3,000, or $139/month for up to $10,000. Auto Bundle Detection is a $49/month add-on. Paid plans include a seven-day free trial.
Pros: Huge feature set and built-in testing.
Cons: Revenue caps mean your bill climbs as bundles succeed.
Kaching is built around one thing: getting a shopper to pick "buy two" instead of "buy one." Quantity breaks, BOGO, volume discounts, and free shipping offers sit right under the add-to-cart button.
Key features:
Pricing: Free on development stores. Starter is $14.99/month for up to $1,000 in additional revenue, Scale is $29.99/month for up to $5,000, and Pro is $59.99/month for up to $10,000. Yearly plans save up to 27%. Seven-day free trial.

Cons: Revenue-capped tiers, and it's focused on offers more than component inventory.
Easy Bundles by Skai Lama makes polished build-your-own bundle pages. If your brand sells gift boxes, sample packs, or a "pick any six" deal, this one's worth a look.
Key features:
Pricing: Free for up to $500 in monthly bundle sales. Essential is $29/month for up to $3,000, Growth is $49/month for up to $5,000, and Scale is $99/month for up to $10,000. The Free and Essential plans aren't available to Shopify Plus or Advanced stores. 15-day free trial.

Cons: Revenue caps, and Plus stores start at $49/month.
Bundler's free plan is quite generous. It includes unlimited revenue and orders, buy X get Y, volume discounts, quantity breaks, product page upsells, and Shopify POS support.
Key features:
Pricing: Free forever. Premium is $9.99/month and Executive is $19.99/month, each with a seven-day free trial and no cap on bundle revenue.
Pros: The best free plan here, low flat pricing, and POS support.

Free gifts move people. BOGOS specializes in gift with purchase, BOGO, and buy X get Y offers, with bundles and a bundle builder on paid plans.
Key features:
Pricing: Free for 30 orders (lifetime). Basic is $29.99/month for 300 orders, Grow is $49.99/month for 600 orders, and Plus is $109.99/month for 2,000 orders, each with $0.05 per extra order. Which paid plan you can pick depends on your Shopify plan. Seven-day free trial.
Pros: The deepest gift and BOGO toolkit, plus a dedicated Shopify Plus plan.
Cons: Order limits add overage fees, and the free plan works more like a trial.
AOV.ai Bundles Quantity Breaks is listed as free on the Shopify App Store. It covers quantity breaks, volume discounts, and the core bundle types, and it pairs with the AOV.ai cart drawer.
Key features:
Pricing: The listing shows one free tier.
Pros: Free and easy to pair with its cart drawer.
Cons: The listing doesn't detail inventory sync, and the integration list is short.
Unlimited Bundles & Discounts by Revy Apps charges a flat fee based on your Shopify plan, so you won't get a surprise bill after a big month.
Key features:
Pricing: Free up to $100 in bundle sales. Paid plans are $9.99, $19.99, or $29.99 per month, depending on your Shopify plan.
Pros: Predictable flat monthly fee with no revenue caps on paid plans.
Cons: The free plan runs out fast, and analytics are basic.
Shopify Bundles is Shopify's own free app. It handles fixed bundles and multipacks at a fixed price, and inventory updates in real time so you don't oversell.
That's about it. No mix-and-match, no build-your-own bundles, and no quantity breaks. Shopify's developer docs also note that bundles built on its bundle APIs can't be sold with selling plans like subscriptions. Reviewers mention option limits on apparel bundles with several sizes and colors.
Pricing: Free.
Pros: Free, native, and accurate real-time inventory tracking.
Cons: Limited bundle types and limited design.
Under the hood, Shopify bundle apps build bundles in one of three ways. It sounds technical. It's also the difference between a smooth BFCM and a warehouse full of confused pickers.
1. Discount-based bundles. The shopper adds the real products to cart, and a discount applies once the bundle conditions are met. Most quantity breaks, BOGO deals, and frequently bought together widgets work this way, including Kaching, Bundler, and Rebuy Dynamic Bundles. Inventory stays simple because you're selling the products you already stock.
2. Variant-based bundles. The app creates a new bundle product or variant with its own bundle SKU, then syncs inventory back to the component SKUs and breaks the order down for fulfillment. Simple Bundles & Kits and Bundles.app are strong here. The upside is a dedicated bundle product page. The downside is more products and custom product variants and options to manage, plus Shopify's variant limits.
3. Cart transform bundles. Shopify's Cart Transform Function groups individual items into one bundle line in the cart. According to Shopify's developer docs, checkout shows the bundle as a group, order lines keep each component with a reference to the bundle, and fulfillment apps can read the bundle details. That keeps component inventory accurate without extra SKUs. The Rebuy Bundle Builder and several build-your-own apps use the Cart Transform API.
The right approach depends on your bundle type. Quantity breaks and dynamic pricing work well as discount-based bundles. Kits with conditional rules and custom bundle deals often fit cart transform. If your 3PL needs a single bundle SKU, go variant-based. Whatever you pick, run an A/B test of bundle widget variants before you roll it out store-wide. The winner isn't always the one you expect.
Ask every bundle app one thing: what the warehouse sees when someone buys a bundle.
Good bundle apps handle inventory tracking at the component level. Sell one "morning routine" kit and the cleanser, serum, and moisturizer each drop by one. Great apps also push a bundle order breakdown to your 3PL so pickers see component SKUs, not a mystery item.
What to look for:
For heavy inventory needs, Simple Bundles & Kits leads with 3PL, WMS, ERP, and multi-location POS support. Easy Bundles syncs bundle inventory with 3PLs. Bundles.app is another solid option, with plans from $19/month and Shopify Plus tiers based on order volume, up to more than 100,000 orders a month. Rebuy bundles add the real products to the order without new SKUs, so your 3PL fulfills the same SKUs it already knows.
Shopify Plus brands bundle at a different scale. Think BFCM gift sets, wholesale packs, and retail stores that need POS compatibility. Here's what matters at that level:
Our picks for Plus: Rebuy for personalized bundles connected to the cart, checkout, and post-purchase. Simple Bundles & Kits (Plus plan, $149/month) for inventory-heavy kits and headless stores. BOGOS (Plus plan, $109.99/month) for gift-led promotions. Bundles.app for high-volume inventory sync.
For complex bundling scenarios like multi-step gift builders, market-specific bundles, or headless storefronts, ask each vendor to demo the setup on your own catalog before you sign. And if you want bundles to follow the shopper past the cart, the Rebuy Checkout & Post-Purchase package adds checkout offers, checkout content blocks like reviews and ratings, and one-click post-purchase offers. (Offers inside checkout need Shopify Plus, since Shopify sets that limit.)
Free is a great price. Just read the fine print, because "free" means different things on different listings.
Before you commit, check whether the free plan includes a bundle-builder page and theme app blocks, or just a basic product page widget.
Bundle app pricing comes in four flavors. Knowing which one you're on saves you from a nasty surprise in your best month.
Also check for add-on fees (FBP charges $49/month for Auto Bundle Detection), the annual billing discount (17% on Simple Bundles, up to 27% on Kaching, 10% on Rebuy), and free trial length (seven days for FBP, Kaching, Bundler, and BOGOS, 14 days for Rebuy, 15 days for Easy Bundles and Bundles.app).
Here's the math in practice. Say your store does about $8,000 a month in bundle sales. Based on October 2026 listings, that's roughly $139/month on FBP, $59.99/month on Kaching Pro, $99/month on Easy Bundles Scale, and $9.99 to $19.99/month on Bundler. Pricing transparency matters, so run your own numbers at your expected bundle revenue, not today's.
Bundles are one part of an AOV strategy. The brands that get the most out of them show the right offer at every step.
AI-powered cross-sell tools use behavioral targeting (what a shopper browsed, bought, and added) to choose the bundle. Automatic discounts keep the offer frictionless, and real-time inventory sync keeps you from recommending something that's sold out. Track it all with conversion analytics so you know which placement earns its spot.
Most bundle apps also plug into a cart drawer. Kaching pairs with its own cart app, AOV.ai Bundles with the AOV.ai Cart Drawer, FBP with UpCart, and BOGOS with slide cart drawers. Rebuy bundles run inside the Rebuy Smart Cart, so bundle offers can appear in the cart itself.
AI-powered product pairing helps too. Rebuy Dynamic Bundles choose pairings from browsing and purchase history, and the rules engine lets you step in when the AI needs a nudge (say, never pairing a winter parka with sunscreen).
This is where single-purpose bundle apps and Rebuy differ most. Rebuy connects Dynamic Bundles, the Rebuy Bundle Builder, mix and match bundles, the Rebuy Smart Cart, and post-purchase offers, so a shopper sees one consistent set of recommendations from product page to thank you page.
You can create bundles on Shopify with the native Shopify Bundles app or with a third-party app from the Shopify App Store. Here's the process.
The best Shopify bundle app is the one that fits your bundle type, your store size, and your budget. Start with the bundle type, then match the app to your stage of growth.
New stores: Start with a free plan, like Bundler or Shopify Bundles, and one fixed bundle or quantity break on your bestseller. Keep it simple until you have data.
Growing brands: Look for mix-and-match bundles, a bundle builder page, A/B testing, and scalable pricing plans. This is the stage where revenue caps start to bite, so compare flat and capped pricing at next year's volume.
Shopify Plus and enterprise brands: Prioritize SKU handling, fulfillment accuracy, personalized product selections, and real support. Your bundles should connect to your cart, checkout, and post-purchase offers instead of living on one product page.
Check three details: customization options (layouts, colors, and variant selection), scalable pricing plans that won't punish your growth, and support for an A/B test so you can prove the bundle works.
It depends on your bundle type. Rebuy is best for personalized bundles across the store, Simple Bundles & Kits for inventory and 3PL sync, Kaching for quantity breaks, Easy Bundles for build-your-own boxes, and Bundler for the best free plan.
Yes. Shopify Bundles is a free app from Shopify that creates fixed bundles and multipacks with real-time inventory tracking. It doesn't support mix-and-match bundles, build-your-own bundles, or quantity breaks.
Yes. Bundler's free plan includes unlimited revenue and orders, with quantity breaks, volume discounts, and buy X get Y. AOV.ai Bundles is also listed as free on the Shopify App Store.
They can. Test your product page speed before and after you install, and choose apps that install with theme app blocks instead of injected code. A good bundle widget loads without slowing the add-to-cart button.
Not with Shopify's native bundles, which can't be sold with selling plans like subscriptions. Some apps support subscription bundles, including the Rebuy Bundle Builder (with Recharge, Skio, and Stay.ai), Easy Bundles on the Growth plan and up, and Simple Bundles & Kits subscription boxes.
Most cost between free and $150/month. Revenue-capped apps charge more as bundle sales grow, order-based apps charge by monthly orders, and flat-fee apps charge the same every month.
The best bundle app fits the way your brand sells. Pick the bundle type first, check how the app handles inventory, and run the pricing math before your best month blows past a revenue cap.
