Managing bundles
Bundle as Product
A bundle as product gives your bundle its own Shopify product page: its own URL, its own images, and a single Add to Cart button. Shoppers add it to their cart and check out like any other product. The items ship together; no separate listing needed.
This is separate from the bundle widget, which still appears on your component products' pages. The bundle product page is an additional entry point.
#When to use it
- You want the bundle to appear in search results, collections, and sales channels.
- The bundle is a gift set, starter kit or seasonal pack you want to promote as its own product.
- You want a shareable URL for a specific bundle.
#Which bundle types support it
Fixed Bundle, Buy X Get Y, and BOGO. Volume Discount and Mix & Match do not support bundle as product.
#Turning it on
The Bundle as product section is on the Discount step (step 2 of 4) of the bundle editor.
- Open the bundle editor. On a new bundle, the Discount step is the second step. On an existing bundle, navigate to that step.
- Turn on
Create product for bundle, the switch at the top right of the Bundle as product section. - Fill in a title for the Shopify product. It auto-fills from the bundle name on create; edit it independently at any time.
- Add a description and media images if you want. Upload your own, or use
Add media from included productsto pick images from the bundle's products. Up to 15 images. - Continue through the wizard and save. Radius creates the Shopify product when you first save with the toggle on.
On an existing bundle with a product already created, an Edit Shopify product button opens the Shopify admin product page in a new tab. Fields you can only edit there (product category, tags, GIF/video media) are listed in a tooltip on that button. Title, description, and media images sync back to Shopify automatically every time you save the bundle.
#Parent variants
When all of a bundle's items are pinned to a single variant (no shopper choice), one Shopify variant is created and represents the whole bundle.
When one or more items offer a variant choice (for example, a shirt where the shopper picks size), Radius creates one Shopify variant per combination. The shopper picks from the theme's standard variant picker on the product page and the contents list updates to show which items they will receive.
The editor shows a warning if you add more than three choice items (Shopify allows at most three product options) or if the combination count exceeds the platform's variant limit.
#Stock and price
Stock follows the component items. When you choose Keep the bundle together (see below), Radius attaches the components to the bundle product using Shopify's native bundle API. The parent product goes out of stock automatically when any component does, and Shopify enforces this at checkout.
If a component has inventory tracking turned off in Shopify, or is set to keep selling when out of stock, it can never trigger a stock-out. The editor names any such components in a warning banner. Turn on inventory tracking for those products in Shopify to close the gap.
Price is calculated from the component prices and your bundle discount when you save. If a component's price changes later, the app recalculates the bundle price automatically once Shopify reports the change. You don't need to re-save the bundle.
#In the cart: grouping choices
In the cart (in the same card as Bundle as product, on the Discount step) controls what happens after a shopper adds the bundle, whether from this page, the widget, a collection, or search.
| Option | What the shopper sees | Stock | Shopify admin components |
|---|---|---|---|
Keep the bundle together | One cart line, items listed underneath | Follows components via Shopify's native bundle API | Shown in the Bundled products card |
Add items separately | One cart line per item, each adjustable | Checked per item independently | Not shown (no native attachment) |
Keep the bundle together is the default once the bundle is a product. With Bundle as product off, Add items separately is selected, since nothing can be kept together; picking Keep the bundle together turns Bundle as product on. Under the choice, a short line sums up the result, for example the number of variants it adds and "stock follows the components". Choose Add items separately when shoppers should be able to change quantities or remove individual items from the cart, or when your products already have complex variant configurations that cannot map to the three-option limit.
Re-save the bundle after switching so the storefront picks up the change.
#What shoppers see on the product page
The product page shows your theme's standard layout: title, images, price, a variant picker if the bundle has choices, and the Add to Cart button. The bundle widget doesn't appear here.
Radius adds a What's included contents list directly above the Add to Cart button. It shows each item in the bundle, with product images and prices if those display settings are on. On Buy X Get Y and BOGO bundles, any item the shopper receives free is marked FREE (only when the reward discount is 100%).
If the bundle has variant choices, the contents list updates as the shopper changes the picker to show exactly which products and variants they will receive.
#What you see in Shopify admin
When Keep the bundle together is on, the bundle's product page in Shopify admin shows a Bundled products card from Radius Bundles. It lists the components (per variant, on a bundle with choices) and says stock follows them. The list is read-only, because the app rewrites it whenever the bundle is saved; its edit icon opens the bundle in Radius. The card doesn't appear for Add items separately bundles, which have no components attached.
#Turning it off or deleting the bundle
Turning off the toggle on an existing bundle shows a confirmation. Saving with the toggle off permanently deletes the Shopify product from your store. This can't be undone from within Radius; you'd need to recreate it. The bundle itself is unchanged.
Deleting the bundle also deletes the Shopify product. Orders placed before the deletion are not affected.
#Common mistakes
Expecting the bundle widget to show on the product page. It does not. The widget is hidden on the bundle's own product page. The What's included list appears in its place. If you want the interactive widget, add the Radius app block to any of the component products' pages instead.
Untracked inventory not triggering stock-out. If the editor shows a warning about untracked components, the bundle will not go out of stock when those items run out. Enable inventory tracking in Shopify (Products → edit the product → Inventory) so those products can trigger a stock-out.
Switching to Add items separately and forgetting to save. The storefront reads the setting from the saved bundle. Changing the toggle without saving has no effect on the storefront.
Editing the Shopify product directly. Title, description, and media images are synced from the bundle editor when you save. Changes you make to those three fields directly in Shopify admin will be overwritten the next time you save the bundle.
