bundle exception log flow from offer and component evidence through costs to contribution, compatibility, decision, and restoration — Original bundle exception log diagram using invented amounts and no customer records.

Audit bounds, dates, and coercion

Add four errors to the exception log: counts above current fixed-bundle limits, symbols or words accepted as numbers, a seller policy newer than its source review, and a missing shared confirmation.

Record the rejected input, official boundary, correction, reviewer, output-quarantine count, and whether a new configuration version was required.

Detect invented bundle-level shipping profiles

Shopify bundles use the shipping profiles of their component products. Treating a bundle as if it owned one profile can hide combined rates, origins, zones, weights, and fulfillment costs.

Map component assignments and test representative checkout carts. Keep shipping-cost economics and customer rate evidence distinct.

Subtracting one discount twice

Common errors include double-counting the discount, omitting one component variant, using retail value as component cost, ignoring inventory constraints, applying payment fees to the wrong base, hiding fulfillment, allocating a full app bill, dropping return loss, combining a native bundle with subscriptions, and treating one recurring order as lifetime value. At checkpoint 1, the bundle exception log records the accepted value or state, unit, source date, source owner, evidence maturity, rejected alternative, and whether the change affects selling price, component cost, payment, fulfillment, app, return reserve, contribution, target, compatibility, inventory, checkout, or decision.

Bind subtracting one discount twice to one offer type, component map, inventory state, channel, checkout, currency, period, owner, reviewer, and restoration packet. Keep draft, active, tested, failed, changed, corrected, and restored states separate. If component, quantity, SKU, offer type, selling plan, currency, period, or cost convention changes, open a new packet rather than averaging unlike offers.

Dropping a component variant

Common errors include double-counting the discount, omitting one component variant, using retail value as component cost, ignoring inventory constraints, applying payment fees to the wrong base, hiding fulfillment, allocating a full app bill, dropping return loss, combining a native bundle with subscriptions, and treating one recurring order as lifetime value. At checkpoint 2, the bundle exception log records the accepted value or state, unit, source date, source owner, evidence maturity, rejected alternative, and whether the change affects selling price, component cost, payment, fulfillment, app, return reserve, contribution, target, compatibility, inventory, checkout, or decision.

Bind dropping a component variant to one offer type, component map, inventory state, channel, checkout, currency, period, owner, reviewer, and restoration packet. Keep draft, active, tested, failed, changed, corrected, and restored states separate. If component, quantity, SKU, offer type, selling plan, currency, period, or cost convention changes, open a new packet rather than averaging unlike offers.

Using retail value as component cost

Common errors include double-counting the discount, omitting one component variant, using retail value as component cost, ignoring inventory constraints, applying payment fees to the wrong base, hiding fulfillment, allocating a full app bill, dropping return loss, combining a native bundle with subscriptions, and treating one recurring order as lifetime value. At checkpoint 3, the bundle exception log records the accepted value or state, unit, source date, source owner, evidence maturity, rejected alternative, and whether the change affects selling price, component cost, payment, fulfillment, app, return reserve, contribution, target, compatibility, inventory, checkout, or decision.

Bind using retail value as component cost to one offer type, component map, inventory state, channel, checkout, currency, period, owner, reviewer, and restoration packet. Keep draft, active, tested, failed, changed, corrected, and restored states separate. If component, quantity, SKU, offer type, selling plan, currency, period, or cost convention changes, open a new packet rather than averaging unlike offers.

Subtracting one discount twice: control test 1

Change only the subtracting one discount twice input in a synthetic fixture. Hold currency, period, payment convention, unrelated costs, target, owner, reviewer, compatibility statement, and evidence state constant. Show whether the change creates Block, Review, Ready, a new contribution difference, or only an explanatory note.

Correct the source, preserve both versions, rerun fixed-bundle and separate subscription-product fixtures, and reconcile after actual inventory, checkout, discount, provider fee, app charge, fulfillment, return, or renewal-order evidence arrives. The tool cannot access Shopify, create an offer, publish, or expose customer data.

Official Shopify boundary for the bundle exception log

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 bundle exception log

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.
