Official Shopify boundary for the fixed-bundle worksheet
Shopify documents bundle types, bundle-app and upgraded-checkout eligibility, component inventory behavior, SKU considerations, channels, returns, fixed-bundle creation, discounts, purchase options, subscription apps, and checkout behavior. Capture current pages and protected store evidence because plan, channel, app, eligibility, and workflow can change.
The controlling boundary is explicit: Shopify bundles are incompatible with purchase options, including subscriptions, preorders, and try-before-you-buy. A recurring box must be modeled as a separate subscription product and selling-plan packet, not as a native bundle with a purchase option.
Privacy, release, and restoration for the fixed-bundle worksheet
Use invented fixtures and aggregate evidence summaries only. Keep names, emails, addresses, order identifiers, payment details, subscription contracts, cancellation records, component inventory, SKUs, checkout captures, app bills, credentials, provider terms, and raw exports out of public pages and analytics.
Before indexing, pass type, unit, integration, build, content, similarity, metadata, image, link, privacy, accessibility, mobile, backup, deployment, and live checks. Search signals are later measurements; failed compatibility, inventory, checkout, ownership, or restoration evidence still stops release.
