A bundle creates value when it raises willingness to pay, simplifies choice or better allocates heterogeneous valuations. It can also destroy contribution by discounting components already bought, adding unused-service cost or moving the best customers to a less profitable offer. The decision must compare choice paths, not bundle adoption alone.
Decision and method.
Launch a bundle only when incremental contribution after transfers, specific costs and effects on separate sales exceeds the current architecture. Estimate purchases of A, B, both and no purchase without a bundle from behaviour, experiment or a choice model, not a single stated intention. Compare pure bundle, separate sale and mixed bundle on the same population; test price, component availability, eligibility, usage limits and visibility. For each bundle buyer calculate bundle contribution minus contribution of the forgone alternative minus specific cost, separating new customers, A buyers, B buyers and both buyers. Vary new adoption, double-buyer cannibalisation, service cost and usage rate; publish the threshold that erases the gain.
Worked example.
Without a bundle, 300 prospects buy A at €50 contribution and 160 buy B at €40. With a mixed bundle, 240 choose the bundle at €70, 120 keep A and 40 keep B. Launch cost is €2,000. Baseline: 300 × 50 + 160 × 40 = €21,400. Mixed bundle: 240 × 70 + 120 × 50 + 40 × 40 = €24,400. After its €2,000 cost, net gain is only €1,000. A decrease of 15 new purchases almost removes the gain, so launch must stay testable and reversible.
Checks and limits.
Compare separate sale, pure bundle and mixed bundle; connect every adoption to a counterfactual alternative; include discount, usage, support and complexity costs; publish the new-buyer threshold for profitability. Declarative models can overstate interest in lightly used components; valuations can change with learning; low-marginal-cost digital bundles do not generalise to physical goods.
