WooCommerce offered several bundle approaches: Grouped Products (WooCommerce core), WooCommerce Product Bundles (premium plugin), and third-party plugins like YITH Product Bundles. Shopify now has native bundle support via the Shopify Bundles app (launched 2023) plus a mature app ecosystem. The right approach depends on bundle complexity, pricing strategy, and whether you need inventory management at the component level.

WooCommerce bundle types and Shopify equivalents

WooCommerce approach	Shopify equivalent	Best for
Grouped Product	Collection page + manual cart	Displaying related products together (not true bundling)
WooCommerce Product Bundles	Shopify Bundles (native) or Bold Bundles	Fixed component bundles with pricing
Build-your-own bundle	Product Options app + custom logic	Customer-configured bundles (choose your flavours)
Virtual bundle (kit)	Shopify Bundles or manual product with description	Gift sets, starter kits
Subscription bundle	ReCharge subscription + bundle product	Monthly subscription with multiple components

Shopify Bundles (native app)

Shopify's own Bundles app (free, in Shopify App Store) supports two types:

Fixed bundles

Set components: e.g., Product A × 1 + Product B × 1 + Product C × 2
Bundle price: set below the sum of component prices (the discount)
Inventory: Shopify Bundles tracks inventory at the component level — when a bundle sells, each component's stock reduces accordingly
Variants: bundles can have variants (e.g., bundle in Small or Medium size)
Best for: gift sets, starter kits, complementary product bundles with a fixed configuration

Mix-and-match bundles

Customer selects specific products from a defined list to fill the bundle
Example: "Create your own 6-bar soap bundle — choose any 6 scents at £20"
Defines total quantity (6 items) and the product pool they select from
Bundle price: fixed total price regardless of which items customer selects
Best for: customizable gift sets, "choose your flavour" bundles, sample packs

Bold Bundles

For more complex bundling than Shopify Bundles offers:

Percentage discount on bundles (not just fixed price): "Buy any 3 products from this collection, get 20% off"
Multi-tier bundle pricing: buy 2 get 10% off, buy 4 get 20% off, buy 6 get 30% off
Display on product page: "Frequently bought together" style bundle suggestion
Best for: quantity-break pricing, tiered discounts, cross-category bundles

Bundle pricing strategies

Strategy	Example	When to use
Fixed bundle price	3 products for £45 (individual total: £55)	Gift sets, starter kits
% discount on bundle	Buy 3, save 15%	Quantity incentive, stock clearance
Bundle vs individual comparison	Show "Save £12" badge on bundle	Highlighting bundle value
Free product in bundle	"Buy X, get Y free" — Y priced at £0 in bundle	New product trial, clearance item
Tiered bundle pricing	2 for £20, 3 for £28, 6 for £50	Supplements, candles, repeat-purchase products

Build-your-own bundle implementation

For fully customizable bundles (customer picks individual items from a catalogue):

Shopify Bundles mix-and-match: handles up to ~50 products in the selection pool. Customer-facing selector UI included.
Product Options + cart logic: For very large catalogues (200+ selectable items), use Product Options (Infinite Options, Bold) to show a dropdown per "slot", then custom cart logic validates quantity.
Build-a-Box apps: Specialized apps like "Build a Bundle" or "Bundler" offer richer UX for complex build-your-own scenarios.
The best build-your-own experience: customer sees all available products as clickable cards, selects their quantity, sees running total, and checks out as one bundle line item.

Kit/bundle inventory management

When components are sold individually AND as part of a bundle, inventory management requires care:

Shopify Bundles (native): deducts component inventory automatically when bundle sells. If any component is out of stock, the bundle becomes unavailable. This is the correct behaviour for shared inventory.
No component inventory deduction: if you create a bundle as a simple product with description listing components, Shopify doesn't track component stock. You need to manage component inventory manually (risky for popular bundles).
Bundle-specific stock: if bundle components are sourced/packaged specifically for the bundle and not sold separately, you can track inventory at the bundle level only (not at component level).

WooCommerce Product Bundles migration

Exporting WooCommerce bundle data

WooCommerce Product Bundles stores components in wp_postmeta as a serialized array under _wc_pb_bundled_items
Export component list per bundle: SQL query or WooCommerce export + manual mapping
For each WooCommerce bundle: note the parent product, component products, and any component quantity multipliers

Rebuilding in Shopify

Fixed bundles with up to 20 components: rebuild directly in Shopify Bundles app — fastest approach
Large number of bundles: use Shopify Bundles API to create bundles programmatically from the exported WooCommerce bundle data
WooCommerce Grouped Products: replace with a Shopify Collection page that groups the related products. No true equivalent — Grouped Products in WooCommerce were navigation tools more than purchase tools.

Bundle display on product pages

Shopify Bundles creates its own bundle product with a dedicated product page and URL
Cross-reference: add a link from each component product page to the bundle page ("Also available in our Starter Kit")
Metafield for bundle reference: product.metafields.ns.available_in_bundle (product_reference) — links to the bundle product that contains this item
Bundle badge on collection pages: tag bundle products with bundle tag and show "Bundle" badge via CSS on collection pages

Bundle migration checklist

Audit current WooCommerce bundles: list all bundles, their components, and pricing
Choose Shopify bundle approach: Shopify Bundles app (most cases) or Bold Bundles for % discount bundles
Install Shopify Bundles app
Recreate fixed bundles in Shopify Bundles: define components and bundle price
Create mix-and-match bundles for "choose your own" scenarios
Verify component inventory deduction: test bundle purchase → confirm component stock reduces
Replace WooCommerce Grouped Products with Shopify Collections
Add bundle reference metafields to component products
Set up bundle badge on collection page for bundle products
Review bundle pricing: compare bundle total vs sum of components to ensure savings are visible

The most overlooked aspect of bundle migration is inventory management. WooCommerce Product Bundles tracked component inventory correctly — when the bundle sold, WooCommerce deducted stock from each component. If you recreate bundles in Shopify as simple products (just a product with a description listing what's included, no Shopify Bundles app), Shopify doesn't know the components and doesn't deduct their stock. This means a bundle can sell when a component is actually out of stock. Always use the Shopify Bundles app (or an equivalent with component inventory tracking) if the bundle's components are also sold individually and share the same inventory pool.
