12 Best Bundle Apps for Shopify (2026): Pricing, Native vs App & AOV Math
The best bundle app for Shopify depends on the bundle you're selling. For quantity breaks on a hero product, use Kaching Bundles. For mix-and-match and frequently bought together, use Fast Bundle. For cheap, flat-priced classic bundles, use Bundler. For build-your-own boxes, use Easy Bundles. If you only need simple fixed bundles or multipacks, Shopify's free native Bundles app is enough. We're a Shopify CRO agency and don't sell a bundle app, so nothing here is ranked by affiliation.
TL;DR: quick picks
Fixed bundles and multipacks: Shopify Bundles (free). Quantity breaks / single hero product: Kaching. Mix-and-match + FBT: Fast Bundle. Lowest flat price: Bundler. Build-a-box gifting: Easy Bundles. 3PL kitting and inventory: Simple Bundles. Subscriptions: BYOB (Recharge). Headless/Hydrogen: Kitenzo. All ratings and prices as shown on the Shopify App Store on 7 October 2026.

Book a free bundle strategy callWhat is a Shopify bundle app?
A Shopify bundle app lets you sell several products, or several units of one product, as a single offer, usually at a discount. It adds the bundle widget to your product page, cart or checkout, applies the bundle price, and tells Shopify which component SKUs to deduct from inventory and send to fulfillment.
Shopify supports bundles natively through its free Bundles app and, for developers, the Cart Transform Function API. Third-party apps exist because the native option only covers fixed bundles; anything dynamic (mix-and-match, tiers, build-a-box, gifts) needs an app or custom code.
Types of Shopify bundles (and which app type fits)
| Bundle type | What it is | Best for | Native Shopify Bundles? |
|---|---|---|---|
| Fixed bundle / kit | Set products sold together at one price | Starter kits, routines, gift sets | Yes |
| Multipack | Several units of one product | Consumables, socks, supplements | Yes |
| Mix-and-match | Shopper picks N items from a collection | Snacks, beauty, apparel basics | No (app or Cart Transform) |
| Build-your-own box (BYOB) | Multi-step box builder, often with a gift box | Gifting, subscription boxes | No |
| Volume discount / quantity breaks | Tiered price per unit as quantity rises | Single-hero-product stores | No |
| BOGO / Buy X get Y / free gift | Free or discounted item when a condition is met | Promotions, BFCM | No (discounts only) |
| Frequently bought together (FBT) | Recommended add-ons on the product page | Accessories, cross-sell | No |
Can you create bundles on Shopify without an app?
Yes, three ways. 1) Install Shopify's own free Bundles app: it's first-party and available on all plans. 2) Create a separate 'bundle' product manually and adjust stock yourself: cheap, but inventory drifts and fulfillment sees the wrong SKU. 3) Have a developer build a custom bundle with the Cart Transform Function, which is how mix-and-match works natively. If you need option 3, our Shopify app development team builds these.
Shopify Bundles (native) vs a third-party bundle app
Shopify's native Bundles app is rated 2.9★ from 568 reviews while the leading third-party apps sit at 4.9–5.0★. The gap is mostly about expectations: the native app is a reliable fixed-bundle tool, not a merchandising or upsell tool. These are its documented limits, from Shopify's Help Center:
| Capability | Shopify Bundles (free) | Typical third-party app |
|---|---|---|
| Fixed bundles and multipacks | Yes (up to 30 components) | Yes |
| Mix-and-match / dynamic bundles | Only via custom Cart Transform (up to 150 components) | Yes, no code |
| Variants per bundle | Max 3 options, 100 variants | Varies; BundleSuite up to 2,048 |
| Quantity breaks, tiers, BOGO, gifts | No | Yes |
| Inventory | Combined pool, not per location | Some apps sync per location / 3PL |
| Price updates when a component changes | No, set manually | Usually automatic |
| Subscriptions (selling plans) | Not supported | Some (e.g. BYOB + Recharge) |
| A/B testing of offers | No | Some (e.g. Kaching) |
| Cost | Free | Free to ~$199/mo, or % of bundle revenue |
Rule of thumb
If every bundle you sell is a fixed set and your stock lives in one place, start with the free native app. As soon as you want shoppers to choose, quantity tiers, gifts or subscription bundles, you need a third-party app.
The 12 best bundle apps for Shopify in 2026
Every rating and price below was taken from each app's Shopify App Store listing on 7 October 2026. Apps change prices often, so re-check the listing before you install. Ranking is by fit for the most common use case, not affiliation; we have none.
1. Kaching Bundles & Upsells: best for quantity breaks and single-hero-product stores
5.0★ (6,194 reviews). $14.99, $29.99 or $59.99/mo, 7-day free trial. Built for Shopify.
Kaching's strength is quantity breaks ('Buy 1 / Buy 2, save 10% / Buy 3, save 20%'), BOGO and mix-and-match offers rendered as a clean radio-button block on the product page. It ships a native A/B test of offers, which most apps don't. Pick it if most of your revenue comes from one or two hero SKUs (supplements, skincare, pet, gadgets). It's weaker for build-a-box gifting. View on the Shopify App Store →
2. Fast Bundle (FBP): best all-rounder for mix-and-match and FBT
5.0★ (3,518 reviews). Free on development stores; $19/mo (up to $1K bundle sales), $49 ($3K), $139 ($10K).
Fast Bundle covers almost every format: fixed, mix-and-match, BOGO, frequently bought together, build-your-own box, subscription boxes and AI recommendations, with POS support. The catch is revenue-capped billing: your plan climbs as bundle sales grow, so model the fee at your expected bundle revenue before installing. View on the Shopify App Store →
3. Bundler: best low-cost classic bundle app
4.9★ (2,709 reviews). Free plan; Premium $9.99/mo; Executive $19.99/mo. Built for Shopify.
Bundler ranks #2 on Google for 'bundle app shopify' for a reason: it's cheap, flat-priced and simple. Fixed bundles, mix-and-match, tiered discounts and quantity breaks, plus POS. Flat pricing means no surprise as you scale. The widgets are less design-flexible than Kaching's. View on the Shopify App Store →
4. Easy Bundles by Skai Lama: best build-your-own-box builder
4.9★ (1,387 reviews). Free up to $500 bundle sales; $29, $49 or $99/mo. Built for Shopify.
Easy Bundles is the strongest dedicated BYOB / build-a-box experience: multi-step pages, gift boxes, subscription bundles and POS. It suits gifting, snacks, beauty and apparel brands where the box itself is the product. Billing is tied to bundle revenue tiers. View on the Shopify App Store →

Book a free bundle strategy call5. Simple Bundles & Kits: best for inventory, 3PL and kitting
4.9★ (803 reviews). Free (3 bundles, 50 orders); $14, $39 or $149/mo.
If your headache is the warehouse rather than the storefront, start here. Simple Bundles splits bundles into component SKUs for 3PLs and WMSs, syncs stock, and supports Hydrogen and POS. It's the safe pick for kits and pre-packed multipacks shipped by a 3PL. View on the Shopify App Store →
6. BundleSuite: best value for complex multi-step bundles
5.0★ (546 reviews). Free on dev stores; $12, $29 or $49/mo (bundle-sales caps of $1K / $5K / $10K).
BundleSuite handles BYOB, multi-step builders, mystery boxes and very large variant counts (up to 2,048), with POS. It's cheaper than Fast Bundle at similar revenue levels, with a smaller review base. View on the Shopify App Store →
7. BOGOS: best for free gifts and buy X get Y
5.0★ (4,453 reviews). Free plan available. Built for Shopify.
BOGOS is a gift-with-purchase and BXGY specialist that also does bundles. Choose it when your offer is 'free gift over $75' or 'buy 2 get 1' rather than a curated set. View on the Shopify App Store →
8. Pumper Bundles: best free volume-discount app
4.9★ (3,530 reviews). Free plan available. Built for Shopify.
Pumper focuses on volume discounts and quantity breaks with a usable free plan: a good starting point for a new store testing whether tiered pricing lifts AOV at all. View on the Shopify App Store →
9. Bundles.app (Inventory Sync): best for multi-location stock
4.9★ (325 reviews). $19 to $199/mo; 15-day trial.
Shopify's native bundles track stock as one combined pool, not per location. Bundles.app syncs bundle inventory across locations and 3PLs, so it's the fix for retailers with stores plus a warehouse. View on the Shopify App Store →
10. Kitenzo Bundle Builder: best for headless and Hydrogen
4.3★ (264 reviews). Free install, then 1.5% of each bundle transaction.
Kitenzo offers a React SDK for headless storefronts and Hydrogen. The 1.5% transaction fee is cheap when you're small and expensive at scale, so compare it with a flat plan once bundle revenue passes a few thousand dollars a month. View on the Shopify App Store →
11. BYOB ‑ Build Your Own Bundles: best with Recharge subscriptions
4.5★ (72 reviews). $25, $49, $99 or $199/mo, capped by bundle orders. Built for Shopify.
BYOB pairs build-a-box with a Recharge integration, which matters because Shopify's native bundles don't work with selling plans (subscriptions). Subscription-box brands should shortlist it. View on the Shopify App Store →
12. Mix and Match Bundle Builder: simple BYOB on a budget
4.9★ (127 reviews).
A lightweight mix-and-match builder. Reviews praise support but flag two things to test before committing: translating widget text and setup on older (vintage) themes. View on the Shopify App Store →

| Easy Bundles | 4.9 (1,387) | Free to $500 sales; $29/mo | Capped by bundle revenue | Build-a-box |
| Simple Bundles | 4.9 (803) | Free (3 bundles); $14/mo | Flat tiers | 3PL kitting, inventory |
| BundleSuite | 5.0 (546) | $12/mo | Capped by bundle revenue | Multi-step, big variant sets |
| BOGOS | 5.0 (4,453) | Free plan | Flat tiers | Gifts, BXGY |
| Pumper | 4.9 (3,530) | Free plan | Flat tiers | Free volume discounts |
| Bundles.app | 4.9 (325) | $19/mo | Flat tiers | Multi-location inventory |
| Kitenzo | 4.3 (264) | 1.5% per transaction | % of bundle revenue | Headless / Hydrogen |
| BYOB | 4.5 (72) | $25/mo | Capped by bundle orders | Subscription boxes |
The billing model matters more than the sticker price. At $10,000 a month in bundle sales, Kitenzo's 1.5% is $150/mo, Fast Bundle's top listed tier is $139/mo, and Bundler's Executive plan stays at $19.99/mo. Work out your expected bundle revenue first, then compare.
How much can bundles increase AOV? Do the margin math first
Bundles work by raising average order value (AOV), but a discount that's too deep can grow revenue and shrink profit. A worked example:
- Without a bundle: a $40 serum at 70% gross margin earns $28 gross profit per order.
- With a 3-item bundle at 15% off: $40 serum + $30 cleanser + $30 moisturizer = $100, discounted to $85. At the same 70% product margin, cost of goods is $30, so gross profit is $55.
- Break-even test: the bundle earns more per order as long as enough shoppers take it. If 1 in 4 buyers choose the bundle, average gross profit rises from $28 to about $34.75 per order before shipping.
- Watch shipping and fees: heavier boxes cost more to ship, and revenue-capped app fees rise with bundle sales.
Ignore the large AOV-lift percentages in vendor marketing until you've tested them on your own traffic. Our break-even ROAS guide shows how to bake margin into every offer.
How to choose the right Shopify bundle app
- 1. Pick the bundle format first. Quantity breaks, mix-and-match, BYOB or fixed kits each have a clear specialist app.
- 2. Check inventory and fulfillment. Does your 3PL or WMS need component SKUs? Do you stock from multiple locations? If so, shortlist Simple Bundles or Bundles.app.
- 3. Check compatibility. Confirm the app works with your theme (Online Store 2.0), Shopify POS, Markets and multi-currency, subscriptions (Recharge), headless/Hydrogen, and how its discount stacks with discount codes.
- 4. Model the fee at your expected bundle revenue. Flat vs revenue-capped vs % per transaction changes the answer at scale.
- 5. Check page speed. Install on a duplicate theme and compare Core Web Vitals. The Built for Shopify badge is a useful quality signal.
- 6. Test it. Run the bundle as an A/B test against your current product page before rolling it out sitewide.
Where to place bundle offers for the biggest conversion lift
The same bundle can win or lose depending on where shoppers meet it:
- Product page (above add-to-cart): best for quantity breaks and fixed kits, because it changes the first purchase decision.
- Dedicated bundle / build-a-box page: best for BYOB and gifting; link it from navigation and collection pages.
- Cart drawer: best for FBT add-ons and free-gift thresholds, shown at the moment shoppers review their order.
- Checkout and post-purchase: one-click add-ons after payment raise AOV without adding friction before it.
We build high-converting cart drawers as a productized service, Cartdrawer, and optimize the last step with Shopify checkout optimization. To test placements properly, read our guide to A/B testing vs multivariate testing.

Running Hydrogen? Our Shopify Hydrogen agency builds bundle experiences directly with Cart Transform, no app script required.
Common problems with Shopify bundle apps
- Inventory drift: manual bundle products don't deduct component stock. Use the native app or a sync app.
- Oversells across locations: native bundles pool stock; multi-location retailers need Bundles.app or similar.
- Discount conflicts: bundle discounts can stack, or block, discount codes. Test with your BFCM codes before launch.
- Subscription gaps: native bundles don't support selling plans; choose an app that integrates with your subscription tool.
- Theme and speed issues: some widgets break on older themes or add heavy script. Test on a duplicate theme.
- Stale prices: native bundle prices don't update when a component's price changes.

What is the best bundle app for Shopify?
It depends on the bundle. Kaching is best for quantity breaks on a hero product, Fast Bundle for mix-and-match and frequently bought together, Bundler for cheap flat-priced bundles, Easy Bundles for build-your-own boxes and Simple Bundles for 3PL kitting. For simple fixed bundles, Shopify's free native Bundles app is enough.
Does Shopify allow bundles?
Yes. Shopify has a free first-party Bundles app available on all plans for fixed bundles (up to 30 components) and multipacks, and a Cart Transform Function API that developers use for dynamic mix-and-match bundles (up to 150 components).
Can I bundle products in Shopify without an app?
Yes, either with Shopify's own free Bundles app, by creating a manual bundle product and managing stock yourself, or with a custom Cart Transform Function built by a developer. Mix-and-match, tiers and gifts generally need a third-party app or custom code.
What is the best free bundle app for Shopify?
Shopify Bundles is free and fine for fixed bundles. Bundler, Pumper and BOGOS have free plans for dynamic offers, Simple Bundles is free for 3 bundles and 50 orders, and Easy Bundles is free up to $500 in bundle sales.
Why is the Shopify Bundles app rated so low?
It's rated 2.9★ (568 reviews) mostly because merchants expect more than fixed bundles. It has no mix-and-match builder, quantity breaks, gifts or A/B testing, tracks inventory as one pool rather than per location, doesn't reprice automatically and doesn't support subscriptions.
How much do Shopify bundle apps cost?
Most cost $0 to $60 per month for small stores. Some bill by bundle revenue (Fast Bundle $19–$139/mo, Easy Bundles $29–$99/mo, BundleSuite $12–$49/mo), some by orders (BYOB $25–$199/mo) and Kitenzo takes 1.5% per bundle transaction. Prices as listed on 7 October 2026.
What is the difference between a fixed and a dynamic bundle on Shopify?
A fixed bundle is a set group of products sold together. A dynamic (customized) bundle lets the shopper choose which items go in, such as pick any 3. Shopify supports fixed bundles natively; dynamic bundles need an app or Cart Transform.
Do Shopify bundles work with subscriptions?
Not natively: Shopify's bundles don't support selling plans. Apps such as BYOB integrate with Recharge for subscription boxes, and Easy Bundles and Fast Bundle support subscription bundles.
Do bundle apps work with Shopify POS?
Several do, including Fast Bundle, Bundler, Easy Bundles, Simple Bundles and BundleSuite, according to their listings. Check the listing for your plan before installing.
How do Shopify bundles affect inventory?
With the native app or a good bundle app, selling a bundle deducts stock from each component SKU and sends component SKUs to fulfillment. Shopify's native bundles use combined inventory rather than per-location stock, so multi-location stores often add an inventory sync app.
Will a bundle app slow down my Shopify store?
It can. Install on a duplicate theme, compare Core Web Vitals, and prefer apps with the Built for Shopify badge, which have to meet Shopify's performance standards.
Should I use bundles or quantity breaks?
If you sell one hero product, quantity breaks usually win because they don't need a second product. If shoppers buy complementary items, a fixed or mix-and-match bundle raises AOV more. Test both.
How do I A/B test bundle offers on Shopify?
Use an app with built-in offer testing, such as Kaching, or a theme A/B testing tool, split traffic 50/50, and judge on profit per visitor rather than conversion rate alone, because bundles trade discount for order size.
