Shopify Bundles: Where the Free App Stops

You have decided to sell in bundles. Now you are looking at a free app made by Shopify and a page of paid apps asking for a monthly subscription, and nothing on either side tells you what the money buys. The free app is not a trial version of the paid ones — it does a specific set of things completely, and stops at a small number of walls.

This page is about those walls. Not which app is best — we deliberately do not rank them — but which limit of the free app is the one in your way, which class of paid app exists to remove that limit, and what that class costs. Everything here comes from Shopify's own documentation and from the app listings themselves, read in August 2026.

The Quick Verdict

Find your situation in the first column. The rest of the page is the evidence underneath it.

What the free Shopify Bundles app actually gives you

The starting point matters, because a lot of writing about bundles quietly assumes you need an app store to begin. You do not. Shopify ships a first-party bundles app, it is free, and it is not restricted to the larger plans — which means the honest question is never “can I afford bundles?” but “does the free one do the specific thing my bundle needs?”

Two things in that sentence are load-bearing. First-party means the app is Shopify's own, so it is not a subscription that can be repriced out from under you. Fixed product bundles and multipacks is the exact scope — and the word that is missing from it is the subject of the third row in the table below.

Fixed, multipack, mix-and-match: which two it builds

Shopify documents three bundle shapes. The free app builds the first two. The third exists as a concept in the same documentation, which is exactly why merchants assume it is available and then hit a wall halfway through building it.

Can your store run bundles — and where will they show?

These two questions get collapsed into one “requirements” list constantly, and the collapse is expensive. One of them decides whether you can build a bundle at all; the other decides where the bundle you built is allowed to appear. A merchant who confuses them spends a week improving a product page that was never going to be published in the first place.

The admission gate: what your store must already have

The fourth row is the one that stops projects. If your store still carries checkout customisations written in checkout.liquid, product bundles are off the table until that is resolved — and because this is an admission requirement rather than a missing feature, no app that builds product bundles removes it. What replaced checkout.liquid, and what the migration involves, is the subject of our checkout extensibility guide.

Where a bundle can actually be sold

Once the bundle exists, the second gate decides who sees it. Shopify's bundles page names the channels directly: the Online Store, Shop and Shopify POS, plus the Google and YouTube channel with fixed product bundles only. Selling bundles at the till is a relatively recent addition — POS support for bundles launched on September 16, 2024, so guides written before that date describe a narrower world than the one you are working in.

Where the free app stops

This is the section the comparison articles skip, because naming a limit is harder than listing features. Each of the three below is the reason a specific class of paid app exists. The first and the third are stated by Shopify; the second is an absence — what we did not find on the pages named in the box at the end of this section.

The one shape it will not build

A build-your-own box — pick any six sodas, choose four candles from twelve — is the bundle shoppers ask for most visibly, and it is the one the free app does not do. The documentation says so in a single sentence, with no conditions attached to it.

The same page names a third route beyond the free app and the App Store: “If your store is on the Shopify Plus plan, then you can build a custom bundle offering with Bundles APIs.” That is a development project rather than a setting, and it is tied to Plus — worth knowing it exists, and worth knowing it will not appear in your admin on its own. And if what you actually need is the customer changing the product itself rather than choosing a set, that is a different tool entirely: our product configurator guide covers where options, metafields, bundles and configurator apps each stop.

One discount per bundle, not a ladder

A bundle can carry a discount, and the mechanics are published: the discount is calculated on the parent bundle product first, and the amount is then allocated to component products by weighted price, with taxes calculated on the individual components. That is a clean model, and for one price on one bundle it is all you need.

What it is not is a ladder. No page we have found describes several discount steps inside a single bundle — buy three save ten percent, buy five save twenty — across the bundles documentation and the discount-combinations page we read; what those pages describe is one discount, allocated. The boundary of that search is in the box below. How deep a bundle discount should be in the first place, and when bundling is the right merchandising move at all, is a different question with its own answer in our cross-sell guide.

What a bundle cannot sit next to

Shopify publishes a list of features that are incompatible with product bundles, introduced with the line “Certain features are incompatible with product bundles.” It runs to nine items, and it is worth reading in full rather than in summary, because it splits into two halves that cost you very different things:

Three entries on this list send you to a paid class:

• Bundles are not compatible with purchase options — subscriptions, pre-orders and try-before-you-buy.
• Bundles are not compatible with the Shopify Subscriptions app.
• The Shopify Bundles app does not support mix-and-match bundles.

Six entries you design around:

• Bundles are assigned a SKU separate from the individual product SKUs, and a component SKU change means deleting and recreating the bundle.
• Bundles do not have their own shipping profiles; rates are calculated from the profiles of the products inside them.
• Bundles are not compatible with custom products.
• Bundles cannot contain other bundles.
• Bundles do not support import, export or bulk editing capabilities.
• Bundles cannot be used in exchanges, even when exchanging for an identical bundle.

The first two are the same wall seen twice, and they are the reason the subscription-box merchant is the most common person to outgrow the free app on day one. A bundle that renews is not a configuration of this app; it is a different product model, and how subscriptions work on Shopify is where that decision belongs.

Paid apps are not the only way past those walls, and the ten-minute guide below is the clearest map of the alternatives we found: it walks four ways to build a bundle — as a single stocked product, with the native fixed bundles this page is about, as a loosely grouped set, and through the Cart Transform Function API a developer writes. The last one is the route that explains why some stores never buy a bundle app at all. It is a developer's working view rather than documentation, so the limits and prices stay with this page — but on the shape of the choice it agrees with everything above.

What the free app costs you in time

A capability limit stops you once. An operational limit charges you every month, quietly, and it never appears in a feature comparison because there is no feature to compare. These four are the free app's running costs.

The SKU rule deserves its own beat, because it is the one that turns a routine catalogue change into an afternoon. Bundles are not linked to their components by reference in the way merchants assume — the bundle is its own product, with its own identifier.

How many bundles can you actually sell?

Bundle stock is not a number you set. It is derived, every time, from the component with the least room — divided by how many of that component the bundle contains. Shopify documents the rule in one line and then works an example, which is worth reproducing because the rounding is where people get caught.

The rule itself: the scarcest component decides the bundle, and a bundle that takes two of something can only ever be half as available as that component's stock suggests.

Source: Bundle eligibility and considerations — Shopify Help Center. The chair is stocked at 15 and used twice; the desk is stocked at 8 and used once.

Seven, not eight — and the fifteen chairs, which looked like the healthy line in your inventory report, are what capped it. This is the arithmetic to run before you promise a quantity to anyone, because the admin will show you the answer but not the reasoning.

Overall stock, not stock per location

One more property of that number: bundles do not track inventory by location, but by overall stock. For a single warehouse that changes nothing. For a store selling from three locations, or from a shop floor and a stockroom, the bundle is quoting a total that no single location can actually fulfil — which is a routing problem before it is a bundling problem, and our multi-location inventory guide is where that one gets solved.

Which limit is actually blocking you?

The verdict at the top answers by your single dominant blocker. This answers when you have more than one — it crosses the shape of your bundle, the shape of your discount, whether it has to renew or go to trade buyers, how much your catalogue moves, and what your checkout runs on, and it tells you which of those to solve first. The result names a class of app, not a product; the section directly after the quiz is the table of what each class costs.

What each class of paid app removes — and what it costs

There is no ranking here, and that is deliberate. Every “best bundle apps” list ranks tools that do not compete with each other — a subscription-bundle app and a quantity-break app are not alternatives, they answer different questions. What follows is the map by which limit each class removes. Pick the row that matches the wall you actually hit, then compare the listings inside that row on your own terms.

Prices are each listing's own published tiers, as displayed on its App Store page. The first three rows were read on August 11, 2026; the two B2B listings on August 14, 2026. App pricing moves — confirm on the listing before you subscribe.

The second row is the one worth a caution. Quantity breaks and volume discounts are a catalogue-wide pricing lever, not only a bundle feature, and the same app usually powers both — so before you buy it for bundles, look at what you want it to do everywhere else. Our dynamic pricing guide covers that lever on its own. The fourth row is narrower than it looks: those two listings position themselves on wholesale bundling, while the full picture of trading with company accounts sits in our B2B and wholesale guide.

The free tiers, and where they stop

Most of these listings have a free plan, and for a store testing the idea that is the honest first step — provided you know which ceiling ends it. Four of the five listings below cap the free plan, and not in the same units: bundles, monthly orders and revenue earned through bundles all appear as ceilings here. The first row, Bundler, is free without a volume ceiling and stops on a feature instead. The two B2B listings also offer a free tier, and we did not record where either one stops, so they are not in this table.

When the app bill follows your Shopify bill

One pricing model deserves naming, because it changes the arithmetic as you grow: Bundle Bear prices itself against your own Shopify plan — on the tiers displayed in August 2026, $29.99 a month on Basic, rising to $74.99 on Plus. Nothing about the app changes between those tiers; what changes is your platform bill. It is not the only listing that does this: Simple Bundles & Kits labels its own tiers by Shopify plan as well. If you are planning a plan upgrade this year, price the app at the plan you are moving to, not the one you are on.

When should you stop using the free bundles app?

The unhelpful version of this advice is “upgrade when you outgrow it”. The useful version is a trigger you can recognise in advance, so the decision is not made the week before a campaign. Three of these are walls; the fourth is arithmetic.

Notice what is not on that list: bundle count, revenue, catalogue size, or how professional the store looks. None of those appears as a limit on the bundles pages we read — they are the reasons apps get bought, and then the merchant discovers the free app was doing the job all along.

Prove it in your own store before you pay

Steps one to three apply to every route, whichever class the quiz sent you to — an app you buy before the admission gate is checked is an app you cannot use. Step five is the one that separates buying a capability from buying back your own hours, and it is the step people skip, because it is the only one that takes a real catalogue change rather than a click.

The Bottom Line

So the next half hour is worth more than another comparison page: open the free app and build the bundle you actually mean to sell. You will finish it either with the bundle live, or with your wall named in one sentence — and that sentence is what tells you which row of the table above you would be buying.
