The 5 Best Shopify Bundle Apps in 2026, Compared

Bundling is one of the few ways to lift average order value without buying more traffic. The trouble is that the Shopify App Store lists dozens of bundle apps and the listings all promise the same five words: AOV, BOGO, quantity breaks, mix and match, build-a-box. The differences that decide it show up later, in how the discount is enforced and what the app costs once bundles start selling.

Disclosure before anything else: TB Bundles is our own app. Thought Bulb built it, we rank it first here, and it launched on the Shopify App Store this month, so it has no merchant reviews yet. Every other app below is a competitor we were not paid by and do not earn a commission from. All links are plain App Store links with no affiliate tracking, and all ratings, review counts, and prices were checked on September 10, 2026. They move, so confirm them on the listing before you install.

How we compared them

Star ratings on the App Store are close to useless for choosing between bundle apps. Four of the five apps below sit between 4.9 and 5.0. What separates them is narrower:

  • ✓Bundle types. Fixed sets, BOGO, quantity breaks, mix-and-match, and build-your-own are five different merchandising ideas, and not every app does all five
  • ✓Discount enforcement. Shopify Functions recalculates the price server-side at checkout, while theme-side price manipulation and discount codes do not survive every storefront
  • ✓Cart integrity. Whether each bundled item lands in the cart as a real variant, or as one synthetic SKU your 3PL has to unpack
  • ✓Pricing shape. Almost every app in this category meters on the revenue it generates, so the sticker price tells you very little
  • ✓Storefront fit. Whether the widget inherits your theme or needs custom CSS to stop looking like an app

1. TB Bundles

TB Bundles is the app we built, so read this entry as what we optimised for rather than an independent verdict. It covers all five bundle types (fixed bundles, BOGO, multipacks and quantity breaks, mix-and-match, and build-your-own boxes), and every one of them is on every plan, including the free tier, instead of holding mix-and-match or build-a-box back for an upper tier.

Discounts are enforced by Shopify Functions: a discount function plus a cart transform, provisioned when you initialise the app. Shopify recalculates the price at checkout instead of the theme writing it, and the offer links are signed, so a shopper cannot edit a URL into a cheaper bundle. Each item a shopper picks goes into the cart as a real component variant, which keeps inventory, fulfilment exports, and product-level reporting correct. The storefront widget is a theme app embed that picks up your theme's colours, type scale, and corner radius, so it needs no code to look native.

Pricing is metered on monthly bundle sales, like most of this category: free up to $200 in lifetime bundle sales with 5 active bundles, then Starter at $12.99 per month for $1,000 a month and 25 active bundles, Growth at $24.99 for $5,000 and 100 bundles, and Pro at $49.99 for unlimited sales and bundles. The trial on paid plans is 14 days, where most competitors offer 7.

Best fit: stores that want all five bundle types without tier-gating, and that care about discounts holding up on a custom theme or an accelerated checkout path. Watch for: it is new. There is no body of merchant reviews to read, no long public track record, and no third-party migration guides yet. If review volume is how you de-risk an install, one of the apps below is the more conservative choice.

2. Kaching Bundles App & Upsells

Kaching is the most-reviewed app in this category by a wide margin, holding a 5.0 rating from about 5,840 reviews when checked. That is the strongest social-proof signal available in Shopify bundling, and it is why the app sits second here rather than fifth. It covers bundles, gifts, and volume discounts, carries Shopify's Built for Shopify badge, and includes built-in A/B testing, which is rare in this category and genuinely useful if you plan to iterate on offer layout rather than set it once.

Pricing is free to install, then banded on the additional revenue the app generates: $14.99 per month up to $1,000, $29.99 up to $5,000, and $59.99 at the top tier, with roughly 27% off annual billing and a 7-day trial.

Best fit: merchants who want the most-validated option and plan to test bundle layouts. Watch for: it is the most expensive of the five at every revenue band, and revenue metering means your bill grows with the app's success.

3. FBP | Fast Bundle & Upsell App

Fast Bundle held a 5.0 rating from roughly 3,411 reviews when checked, and it has the widest offer surface of any app here. Alongside the standard bundle types it does product add-ons, cross-sell, AI-driven frequently-bought-together, cart-drawer and pop-up placements, and an AI bundle-image generator. If the plan is to collapse a bundle app and a separate upsell app into one line item, price this one out.

Pricing is free to install, with the Standard tier at $19 per month covering up to $1,000 of monthly bundle sales and higher tiers above that, with a 7-day trial and about 21% off annual billing.

Best fit: stores that want bundles plus a full upsell and recommendation stack from one vendor. Watch for: the entry paid tier is the highest of the five, and the breadth is only worth paying for if you will actually run the recommendation and add-on surfaces. Otherwise you are funding features nobody switches on.

4. Pumper Bundles Quantity Breaks

Pumper held a 4.9 rating from about 3,455 reviews when checked. It is the most focused app in this list: quantity breaks, volume discounts, tiered pricing, free gifts, and BOGO, with integrations for cart drawers and page builders. It does not try to be a recommendation engine, and for a store whose whole bundling strategy is "buy three, save 15%", that focus usually helps.

Pricing starts genuinely free up to $300 in generated revenue, then $9.99 per month to $1,000, $29.99 to $5,000, and $49.99 for unlimited. That is the cheapest paid entry point of the five, and the trial is 7 days.

Best fit: quantity-break and volume-discount merchandising on a tight app budget. Watch for: the listing's own pricing taxonomy covers tiered pricing, quantity breaks, volume and cart discounts, free shipping, BOGO, and bulk pricing. Mix-and-match and build-your-own box are absent from it. If build-a-box is on your roadmap, check that before you commit.

Confirm the revenue bands and supported discount types before installing.

5. Bundler » Product Bundles App

Bundler held a 4.9 rating from roughly 2,668 reviews when checked, and on pricing it is the outlier of the category in the merchant's favour. Its free plan advertises unlimited revenue and orders, including Buy X Get Y, volume discounts, quantity breaks, product-page upsells, POS support, and auto-applied discounts. Paid tiers are flat: $9.99 per month for Premium, which adds mix-and-match, tiered and sectioned mix-and-match, quantity-break combinations, custom landing pages, and funnel upsells, and $19.99 for Executive, which adds bundle analytics.

That matters more than it first sounds. Every other app in this list bills more as your bundle revenue grows. Bundler does not meter revenue at all, so a store doing $50,000 a month in bundle sales pays $19.99 rather than $49.99 to $59.99.

Best fit: high-volume bundle programmes where revenue metering would become the largest line item, and stores that want a real free tier rather than a trial. Watch for: analytics sit behind the top tier, and the feature split between Free, Premium, and Executive is where the decision actually lives. Read it carefully, because the free plan does not cover mix-and-match.

Read the Free, Premium, and Executive feature split before choosing a tier.

Two more worth knowing about

Simple Bundles & Kits, when inventory is the hard part

Simple Bundles held a 4.9 rating from about 791 reviews when checked. What sets it apart is operational: single and multi-SKU inventory sync across 3PL, WMS, ERP, and fulfilment systems, plus automatic bundle SKU breakdown, POS, and headless support. Its free plan allows 3 bundles and 50 monthly orders, with paid plans from $14 per month. If your bundles have to decrement component stock across a warehouse system, look here before you look at anything above.

Shopify Bundles, the free native option

Shopify's own Bundles app is free and creates fixed bundles and multipacks directly in the admin, with real-time inventory so you do not oversell components. It is also the lowest-rated app in this comparison by a distance, at 2.8 from 575 reviews when checked, and it does not do BOGO, quantity breaks, mix-and-match, or build-your-own. Install it only if fixed multipacks are genuinely the whole requirement.

How to choose in about ten minutes

Write down the one bundle type you will actually launch first. Most stores do not need five. They need quantity breaks on a hero product, or one build-a-box. Then work through four checks:

  • ✓Confirm the app supports that specific bundle type on the plan you intend to pay for, not just somewhere in the feature list
  • ✓Ask how the discount is applied. Shopify Functions and automatic discounts survive custom themes, headless storefronts, and Buy It Now, while theme-side price rewriting and discount codes are more fragile
  • ✓Model twelve months of cost at your realistic bundle revenue rather than today's, because revenue-metered pricing is where the surprises live
  • ✓Install on a development store, publish one offer, and place a real test order through an accelerated checkout button before you go live

That last step catches more problems than any comparison table. Discount stacking, market-specific pricing, and accelerated checkout paths are where bundle apps break, and they usually break quietly. The widget still renders, the discount just does not apply.

"A bundle app that shows the right price on the product page and the wrong price at checkout is worse than no bundle app at all."

If you are weighing several of these against a specific catalogue, or you have a bundle offer that renders correctly but loses its discount at checkout, that is a diagnosable problem rather than a reason to switch apps again. We deal with discount stacking across multiple product discounts and Functions-based discount migrations regularly.

Tell us the catalogue and the offer you want to run, and we will tell you which of these fits, including when the answer is not ours.

Frequently asked questions

What is the best Shopify bundle app?

It depends on what you are launching. Kaching has the most merchant reviews, Bundler has the only genuinely uncapped free tier, Fast Bundle covers the widest range of offer types, and Simple Bundles is the one to reach for when a bundle has to decrement component inventory. Choose on bundle type, how the discount is enforced, and what the app costs at your bundle revenue.

Do Shopify bundle apps work with automatic discounts?

It depends on the app. Apps built on Shopify Functions register a discount function and a cart transform, so Shopify recalculates the price at checkout. Apps that apply discount codes or rewrite line prices in the theme are easier to break with a custom theme, a headless storefront, or an accelerated checkout button.

How much do Shopify bundle apps cost?

Most of them meter on the extra revenue the app generates rather than charging a flat fee. Entry paid tiers checked in September 2026 ran from $9.99 to $19 per month for roughly $1,000 in monthly bundle sales, rising to $49.99 to $59.99 per month for uncapped revenue. Bundler is the main exception, charging $9.99 or $19.99 per month with no revenue cap.

Is the free Shopify Bundles app good enough?

Shopify's own Bundles app is free and creates fixed bundles and multipacks from the admin with real-time inventory. It does not do BOGO, quantity breaks, or mix-and-match, and it held a 2.8 rating from 575 reviews when checked. It fits only if fixed multipacks are all you need.

Do bundled items stay as separate products in the cart?

In most modern bundle apps, yes. Each selected item is added as a real variant, so inventory, fulfilment, and reporting stay accurate. Apps that create a single synthetic bundle SKU behave differently and usually need inventory syncing to avoid overselling components.
