Marketplace demand is rented; DTC demand is owned—but ownership carries its own CAC and app-stack costs. Contribution margin and strategic option value need to be modeled separately, not blended into one number.

## Rented demand vs owned demand

Marketplaces bring built-in traffic and buyer trust at the cost of referral and fulfillment fees. DTC sites build an owned audience and first-party data at the cost of acquisition spend and an app stack that a marketplace listing never needs.

## Modeling the same SKU twice

Run separate contribution margin calculations for the marketplace listing—referral fee, fulfillment, ads—and the DTC listing—payment processing, shipping, and customer acquisition cost. The two rarely land at the same number for the same product.

## Strategic option value beyond the P&L

DTC often loses on pure contribution margin early on, but builds an email and SMS list plus a repeat-purchase engine a marketplace listing structurally cannot provide.

## FAQ

**Which channel should get inventory priority when supply is tight?**

Whichever channel has the higher contribution margin for that specific SKU right now—revisit the split whenever fee schedules or CAC shift meaningfully.

**Does DTC always win on lifetime value?**

Usually, but only if repeat-purchase and retention programs are actually funded and performing—LTV potential is not automatic just because the channel is owned.
