Bundle Builder provides a way for third-party systems (such as fulfilment, warehouse, and inventory services/applications) to access details about the bundle contents - you can benefit from this easily by using Multiple SKU bundles.

Favoring Multiple SKU Bundles
The vast majority of merchants using third-party services will use Multiple SKU Bundles, as this bundle type is not reliant on Shopify's unique system of line item properties.
Therefore, this bundle type is far more transferrable across multiple systems outside of Shopify.
We strongly advise that any merchants who utilise third-party systems in their store use Multiple SKU bundles instead of Single SKU Bundles.

Proceeding With Caution
As Single SKU bundles are reliant on Shopify’s uniqueline item propertiessystem, this bundle type is not designed to work alongside third-party services.
Advanced knowledge is essential
Configuring third-party services with a Single SKU Bundle can only be done through the API, and therefore requires a significant level of expertise.
Due to the complexity and personalised nature of this process, we are currently unable to offer support for this.
The details of what each bundle contains are stored in a variant metafield.
