Hi! Im hoping to switch from Woocommerce to Shopify. Does anyone know if they have the technology yet in their system like “WPC Grouped Product”? That plugin helps make standalone products that are presented as a group, with the option for the customer to change the amount of product in the kit.
The second app WPC Product Bundles is different in that it is a secondary list of items that can be added onto the first kit with extra discounts if so chosen, and can be either checked or unchecked automatically or manually.
Shopify has no native grouped-product type, so this needs one of two routes. For a fixed kit, the free first-party Shopify Bundles app creates a bundle product that tracks each component’s inventory. For the adjustable-quantity layout you showed, a small Custom Liquid section can list each component with its own quantity input and submit them together in one POST to /cart/add.js using the items array, so a single click adds the whole group at the chosen quantities. Bundle apps cover this too if you prefer no code.
Hello @BBBeyond
Yes, this is possible on Shopify, although it isn’t available as a built-in product type.
For the first requirement (a kit where customers can adjust the quantity of each included product), you can achieve this with bundle apps that support mix-and-match or custom bundles, or with a custom solution that adds multiple line items to the cart in a single action.
For the second requirement (optional add-on products that customers can select or deselect, with optional discounts), several Shopify bundle apps support optional products, add-ons, and discounted extras as part of the bundle experience.
If you’re looking for a no-code solution, apps like Easy Bundles, Bundle Builder, or PickyStory are worth exploring, as they support configurable bundles and optional add-ons. If you want the layout to closely match your current WooCommerce setup, a custom theme section can also recreate that experience.
If you can share whether your kits have fixed products, allow customers to change quantities, or let them swap items, the community can recommend the most suitable approach.
@BBBeyond
Yes, you can create Product bundles such as Frequently bought together, Buy x Get Y, products kits, variants kits, and more similar bundle deals.
I recommend the follwing apps.
Bundlr (Great for scaling, alot of customer reviews and strong user base.)
Sleek bundles upsell (Based on latest technology, all types of bundles exists, but new to market).
kaching bundles (old player in market, a bit expensive and suits the established merchants)
Both plugins map to different things here and only one of them has a first party answer.
For the adjustable quantity kit, the free Shopify Bundles app does have it. On each component there is an Add quantity as an option menu item, which turns that component quantity into a product option. The wall is what that implies. A bundle is capped at 3 options and 100 variants total, so three adjustable components is the ceiling, and three components with five quantity choices each is already 125 variants and over the cap. Fixed bundles go up to 30 components, but only three of them can be quantity adjustable. Worth counting your real kits against that before you commit.
Your second plugin, optional add ons the customer ticks with an extra discount, has no first party equivalent. Bundle discounts get calculated on the parent bundle product and then spread across the components by weighted price, so you cannot price just the add on portion differently.
The Custom Liquid route mentioned above sidesteps the option cap, since it is just N line items in one add rather than one product with variants. The trade is that the kit discount becomes yours to build with an automatic discount or a discount function, and the group itself is not an object Shopify knows about, so nothing reports on it later.
Either way the grouping does not survive the migration as a thing, only the individual products do. How many items are in a typical kit for you, and do more than three of them need adjustable quantity?
If you’re looking for the closest native Shopify equivalent, it’s possible, but it isn’t a one-to-one replacement for those WooCommerce plugins.
For the grouped product/kit functionality (where customers can adjust the quantity of each item in a kit), Shopify offers Bundles, but it’s more limited than WPC Grouped products. If you need customers to set quantities for each product before adding the bundle to the cart, you’ll likely need a dedicated bundle app such as Easy Bundles, Bundle Builder, or Simple Bundles, depending on how flexible your kits need to be.
For the optional add-ons (pre-selected or optional items with discounts), several Shopify bundle apps support this as well. Many let you display recommended add-ons with checkboxes, apply bundle discounts automatically, and even preselect items by default.
From your screenshots, it looks like your kits are fairly customizable, so I’d recommend looking for an app that specifically supports mix-and-match bundles or bundle builders, rather than Shopify’s native Bundles app alone.
If you can share an example of one of your current kit pages, the community can probably recommend the app that’s the closest match to your existing WooCommerce setup.
Shopify can definitely handle this type of setup, but you’ll probably need a bundle app rather than relying on the standard product options. Look for a “mix-and-match” or “build-your-own bundle” app that supports adjustable quantities, optional add-ons, and bundle discounts. I’d test the exact customer flow in a Shopify trial before switching from WooCommerce, since the apps vary quite a bit in how flexible the bundle builder is.
WPC Product Bundles (a main item plus optional add-ons at a discount)
You want a “frequently bought together” / add-ons app: it shows the main product with extra items the customer ticks on or off, with a bundle discount.
There are a lot of different apps for bundles. Absolutely. It’s one the top competitive markets for a shopify app.
The basic product structure has variants but no bundles, that’s why you need an app. But even Shopify recognizes this need, and has their own app, Shopify Bundles.
Yeah, Shopify still has no native “grouped product” type the way WooCommerce/WPC does, so you’ll need an app for this.
The key thing to filter on: you want the customer to be able to change the quantity of each item in the kit and see a running total before they add to cart. A lot of bundle apps only do “pick N items from a collection” at one-each, or fixed preset quantities the merchant sets. That won’t cover the adjustable part.
For per-item quantities with a live total, Simple Bundles & Kits is the closest I’ve seen. The free Shopify Bundles app only does fixed kits, so it’s out for what you’re describing. For the optional add-ons piece (check/uncheck extras with a discount), Frequently Bought Together by Code Black Belt is a solid fit and can run alongside a kit builder.
One thing worth checking before you commit to any of them: how they handle inventory. With birth kits made of standalone products, you want the components’ stock to actually decrement when someone buys a kit, not a separate bundle SKU that ignores the real inventory. Ask each app how they do that on a build-your-own kit, because it varies a lot and it’s the part that bites midwife-supply stores later.
Shopify doesn’t have a native way to group standalone products into one kit with adjustable quantities, or add an optional add-on list under it. Both need a 3rd-party app, so I’d recommend one that covers both instead of running two.
For the add-on part (like "WPC Product Bundles for Woocommerce") → use the Frequently Bought Together feature (Product Add-on widget style) by BOGOS app:
Show a secondary list of optional items with checkboxes
Un-check items by default, customers can freely pick what they want.
Apply a separate discount just to the add-ons
PS: For “auto-check items by default”, please contact our support team; we will customize this for you for free.
To answer your question directly: Shopify does not have a 1:1 built-in UI component for “WPC Grouped Products” out of the box in default themes, but there are 3 main ways merchants handle this exact setup on Shopify:
Shopify released an official Shopify Bundles app that uses Shopify’s Cart Transform API.
Pros: Free, keeps individual inventory accurate across all standalone items in the kit, and works natively with Shopify Checkout.
Limitation: It is designed mainly for fixed kits or simple variant choices. It doesn’t natively render the exact multi-item quantity picker table ([ - ] [ 1 ] [ + ] per line item) shown in your WPC screenshot on standard themes without custom code.
2. Shopify App Store (No-Code App Solutions)
If you want an exact match for your WPC setup with zero coding, several popular apps on the Shopify App Store specialize in Configurable Kits and Optional Add-On Bundles:
Simple Bundles & Kits: Excellent for multi-item kits with individual inventory tracking and line-item quantity inputs.
Fast Bundle & Flexi Bundles: Great for creating “Mix & Match” kit builders and secondary optional add-ons with percentage/flat discounts.
Bundle Bear / Wide Bundles: Popular for custom tier discounts and optional cross-sell checkmarks on product pages.
If you have a developer or want to avoid monthly app fees, you can build this natively on your theme:
Use Shopify Metafields (Product Reference List) to link the child products (Mother's Milk Tea, Rescue Remedy, etc.) to the main Kit product.
Create a custom section template that renders quantity selectors for each linked product.
Use Shopify’s Ajax Cart API (/cart/add.js) to submit all selected items to the cart in a single click as separate line items.
If you want to launch quickly without code, search the App Store for “Mix & Match Kit Builder” or “Simple Bundles”. If you prefer a custom theme section without recurring app costs, a developer can build it using Shopify Metafields and cart/add.js.
Hope this helps with your migration from WooCommerce!
one thing nobody has raised in 14 replies: shopify doesnt hold bundle components together for fulfillment. whichever route you pick, a kit reaches the order as its component lines, and if one of those items happens to sit at a different location than the rest, order routing can split it and the buyer gets two boxes. thats platform behaviour rather than an app feature — the free bundles app and the paid kit builders inherit it the same way. woo never put that in front of you because core woo only has one stock pool per product.
with a few hundred kits going out its worth checking before you commit to anything. open settings > locations and see whether every item you put in a kit really sits at the same place — an old retail location, or one a csv import quietly refilled, is the usual culprit. if stock is spread, move it or put the fulfilling location at the top of the order routing priority list under settings > shipping and delivery. on the order side the components do stay real skus with a reference back to the kit parent, so inventory and refunds keep working per item the way they do for you now. the shortcut that breaks that is turning each kit into one invented product with its own sku.
If you need any help in setting these up, I have found these tutorials that might help:
