This help doc is to troubleshoot when a bundle displays as sold out when the page initially loads.
To troubleshoot sold out errors that appear after clicking the add to cart button, view this help doc here - Error: Cannot be added to cart, Cannot find variant, Product is already sold out
There are two possible scenarios for a "sold out" state. One is the correct, genuine behaviour of a sold out bundle, and the other is an error in the bundle's configuration - normally caused by app conflicts, or markets and locations based settings.
If your bundle product page displays this specific error message in red: "This bundle is sold out"
This means the bundle is genuinely out of stock because required products for a step aren't available. This is expected behaviour.
To resolve this issue, you can view the reason in detail inside the theme editor.
Open the theme editor.
Navigate to the bundle product that is showing the sold out error.
The error will show additional information explaining why the bundle is sold out.
Check this help doc for more information in resolving these errors - Bundle Form Errors
Your bundle shows as "Sold Out" on collection and search pages, and the "Add to Cart" button also displays as "Sold Out" on the product page without the red error message. This indicates there's an issue with the bundle's configuration.
The most common cause of the add to cart button showing as out of stock is usually one of these issues:
Bundle products should be set to 'track inventory' = false, as all of the inventory is managed directly on the component items, not on the bundle product itself.
This setting can be adjusted accidentally by merchants in the Bulk Editor, or by other apps.
To resolve this, open the Bundle Product inside the Biscuits Bundles app, and you should see a warning that will advise the bundle will be corrected when saving its settings again.
You can also adjust this setting inside the product bulk editor in Shopify.
Navigate to your Admin > Products.
Check the bundle products with the issues and then click 'Bulk Edit'.
Show the column for Track Quantity.
Ensure that track quantity is not checked.
Shopify always shows contextual availability to the user based on whether a product is available in a location that ships to the customer's Market.
Ensure all relevant locations are enabled when editing your bundle product inside the Biscuits Bundles app - see the 'Locations' card when editing the bundle product.
Open Settings > Shipping and delivery in your Shopify admin and check if the Default shipping profile has valid shipping rates.
By default, Shopify assigns all native bundle products to the general shipping profile, and they can't be moved to another profile. Because of this, your general shipping profile must include valid rates for all the markets and locations where you want your bundle to be available.
Sometimes, other apps installed on your store can interfere with how bundles are added to the cart.
Apps that handle extra product options, line item properties, or upsells often use their own add-to-cart code, which can override or interrupt the standard process.
Biscuits Bundles is designed to work with your theme's default add-to-cart method, so if another app changes this process, it can stop bundle products and their selection data from being added to the cart correctly.
If you're using an app that adds extra product options, please review the following help article to make sure you've enabled the correct setting: How to enable line item properties to pass through onto bundle components
Please confirm which of these scenarios your store is currently experiencing. If you are unable to resolve this issue, please reach out and we'll assist you promptly.
