Shopify has two different machines under this one word, and which one an app uses decides how it behaves. The first is the native bundles object, where you define the components when you create the bundle. It is bounded on purpose: a limited number of components, the same three-option ceiling as any product, no nesting, and a product cannot both be a bundle and a component of another one. That is fine for a fixed kit and useless for a box the customer fills.

The second is a cart transform function that merges the lines a shopper picked into one, which is how a build-your-own box actually works. Worth knowing what that means downstream: each chosen item stays its own line underneath, so stock comes off each component exactly as if it were sold on its own. There is no separate bundle inventory to run out, whatever the marketing suggests.

The place this gets sharp is subscriptions. Shopify rejects those merge and expand operations outright when a selling plan is present, so a subscription box built this way is doing something else, connected to a separate subscription app. If a monthly box is your business, that is the first question rather than the last.

What to look for in a Btob app

Fixed kit or customer-assembled: Decide which you are selling, because the two are different products built on different mechanisms. A set you assembled and price as one thing, or a box where the shopper picks six of twenty. Apps that claim both usually do one properly.
What the box does to stock: Ask directly whether components decrement individually and what the customer sees when one of the twenty choices runs out mid-selection. On a component-merged box that is normal inventory behavior, which is good, but the interface still has to handle it gracefully.
How the discount is expressed: Pick six for the price of five, tiered pricing, a percentage off the box: these interact with your other discounts and with anything else running at checkout. Test the combination you actually run, especially if a code can be added on top.
What happens after the order: A merged box has to be pickable and packable. Look at how it appears on the order, the packing slip and any warehouse integration, and what a partial refund does to it.
Whether you already run another one: Only one cart transform function installs per app per store, and if several apps have one, all of them run. If you also use an app for fees, upsells or customization, that overlap is worth raising with both vendors before you commit.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
