7 bundle apps compared
The posts in this archive are written to help Shopify teams identify what is weakening buying momentum, what is suppressing AOV, and what deserves action first.
Disclosure: TB Bundles, one of the apps below, is made by Thought Bulb, the studio behind HiveSense. We've marked it. Ratings, review counts, and prices for every app come from its Shopify App Store listing as checked on October 21, 2026.
Bundles are one of the more direct ways to raise order value, because they change what a shopper puts in the cart at the moment of decision. A bundle can turn one item into three, make a second unit cheaper than leaving, or add a free gift above a spend level. That makes the bundle offer a CRO decision as much as a pricing one: where it appears, how it's explained, and whether it's easier to accept than to ignore.

How bundles raise order value
The common bundle types each work on a different buying moment:
| Bundle type | What it does | Works best for |
|---|---|---|
| Fixed set | Sells several products together at one price | Gift sets, starter kits, routines |
| Quantity breaks | Discounts the second or third unit | Consumables, basics, multipacks |
| BOGO | Gives a free or discounted item with a purchase | Clearing stock, simple promotions |
| Mix and match | Lets shoppers choose items from a group at a set price | Apparel, snacks, beauty with many variants |
| Build a box | Lets shoppers fill a box on a dedicated page | Gifting, subscription boxes |
| Spend tiers and free gifts | Rewards a larger cart total | Lifting the whole cart, not one product |
Shopify's own blog gives two examples of how much bundles can matter. HiSmile reports bundles make up more than 80% of its orders and grew cart size about four times, and Lvly reports a 6% year-over-year rise in AOV with more than 150 bundles. Those are brand-reported figures, so expect different results in your own catalog.
What Shopify's native Bundles app can do
Shopify Bundles is free on all plans. Its help center lists the limits:
- Up to 30 components for fixed bundles and 150 for dynamic bundles, 3 options, and 100 variants.
- Inventory is tracked by overall stock, not by location, and availability depends on each component's inventory.
- Bundle prices don't update when component prices change.
- Mix-and-match bundles need a third-party app, or the Bundles APIs on Plus.
- It isn't compatible with subscriptions, pre-orders, try-before-you-buy, exchanges, or nested bundles.
If you only need fixed sets with simple inventory, the native app may be enough. Its 2.8 rating from 570 reviews suggests many merchants want more.
How bundle apps work under the hood
Most current bundle apps use Shopify's Cart Transform function, which lets an app expand, merge, or update cart lines so a bundle appears and is priced correctly. Shopify's docs note that the update operation only works on development stores or Plus, each app can run one cart transform per store, and cart transforms are rejected when a selling plan is present. That last point matters if you sell subscriptions. Check how a bundle app handles subscription products before you rely on it. Our subscription apps guide covers subscription-side bundles.
The apps
TB Bundles (ours)
TB Bundles: Volume & Free Gift supports five bundle types: sets, BOGO, quantity breaks, mix and match, and custom boxes built on their own page. It also adds spend rewards across the whole cart, such as a percentage off above one total and a free gift, added automatically, above another. Bundles show in a product page widget that matches your theme, a progress bar appears in the cart, and discounts apply automatically at checkout. It's built on Shopify Functions (cart transform and discount functions) and uses only the merge operation, so it doesn't depend on Plus. A setting chooses whether a bundle shows as one cart line or as separate lines.
Pricing is free up to $200 of lifetime bundle and reward sales with five bundles, then Starter at $12.99 a month up to $1,000 of monthly sales, Growth at $24.99 up to $5,000, and Pro at $49.99 with no limit. Paid plans have a 14-day trial. It launched in September 2026 and has no reviews yet.

Simple Bundles & Kits
Simple Bundles & Kits by Freshly Commerce is the strongest here on inventory. It splits bundles into their component SKUs and syncs inventory in real time with 3PL, WMS, and ERP systems. It's free for 3 bundles and 50 orders a month, with paid plans of $24 and $39 a month, and $149 for Plus.
Wide Bundles
Wide Bundles focuses on quantity breaks and multipacks, with fixed and mix-and-match bundles too, and includes A/B testing. It prices by extra revenue, from $14.99 up to $500 to $24.99 up to $2,000, with a 14-day trial.
Where bundles fit in a CRO plan
Bundles work best when they answer a question the shopper already has. A few placement principles:
- Show the bundle on the product page near the price, where the decision happens. Our product page gaps guide covers what else belongs there.
- Use the cart for spend tiers and free gifts, not for a second wall of offers. See cart drawer vs. cart page.
- Make the saving obvious: show the bundle price next to the price of buying separately.
- Keep the number of offers small. Several competing bundle widgets on one page make the choice harder.
- Check that bundle discounts and free shipping thresholds work together. A bundle discount can push a cart below your free shipping threshold.
- Check speed after installing. Bundle widgets add scripts to product pages (see Shopify site speed and conversion).

FAQ: Shopify bundle apps
Does Shopify have a built-in bundles feature?
Yes. Shopify Bundles is a free app on all plans for fixed bundles and multipacks. It doesn't support mix-and-match bundles without a third-party app or the Bundles APIs on Plus, and it isn't compatible with subscriptions.
What is the best free bundle app for Shopify?
Shopify Bundles is free on all plans but limited to fixed bundles and multipacks. Bundler has a free plan with no revenue limit for buy X get Y and volume breaks, TB Bundles is free up to $200 of lifetime bundle sales with five bundles, and Simple Bundles & Kits is free for 3 bundles and 50 orders a month.
What is the best bundle builder app for Shopify?
For build-a-box bundles on their own page, Fast Bundle lists build a box, and TB Bundles lists custom boxes built on their own page. Kaching Bundles lists 13 bundle types, including mix and match. Shopify's native Bundles app doesn't offer build-a-box or mix and match without Plus and the Bundles APIs.
What is the best bundle app for Shopify?
It depends on the bundle type and your inventory setup. Kaching Bundles has the most reviews and the most bundle types, Bundler has a free plan with no revenue limit, Simple Bundles & Kits is strongest on inventory sync, and TB Bundles covers sets, BOGO, quantity breaks, mix and match, custom boxes, and spend tiers.
Do bundles increase AOV?
They often do, because they add items at the moment of decision. Shopify's blog cites HiSmile, where bundles make up more than 80% of orders and grew cart size about four times, and Lvly, which reports a 6% year-over-year AOV rise. Results depend on your catalog and how the offer is presented.
Can I do mix-and-match bundles on Shopify?
Not with Shopify's native Bundles app unless you're on Plus and use the Bundles APIs. Third-party apps such as TB Bundles, Kaching, Fast Bundle, Bundler (paid plans), and Wide Bundles support mix and match.
How do bundle apps handle inventory?
Shopify's native app tracks bundle inventory by overall stock rather than by location, and availability depends on each component's inventory. Simple Bundles & Kits splits bundles into component SKUs and syncs with 3PL, WMS, and ERP systems. Check each app's inventory approach if you use a warehouse system.
Do bundle apps work with subscriptions?
Often not directly. Shopify's Cart Transform function is rejected when a selling plan is present, and Shopify's native Bundles app isn't compatible with subscriptions. Many subscription apps offer their own build-a-box features instead.
Pick the bundle type before the app
Decide which bundle fits how your customers buy, whether that's a gift set, a second unit, a mix-and-match pack, or a reward for a bigger cart. Then pick the app that does that type well and handles your inventory. To see where your product pages and cart lose buyers before they see a bundle, run a HiveSense audit.
