DTC vs. Marketplaces: How to evaluate the economics of each channel?

Topic summary

Brands face a challenging economic trade-off between two primary sales channels:

Marketplace challenges:

  • Commissions ranging from 30-50% significantly compress profit margins
  • High fees make sustainable growth difficult

DTC (Direct-to-Customer) challenges:

  • Customer acquisition costs (CAC) on advertising platforms are increasingly expensive
  • Return on ad spend (ROAS) sometimes falls below 0.5, meaning brands lose money on initial purchases
  • Profitability depends heavily on high repeat purchase rates and strong customer retention

Core dilemma:
With both rising CAC and declining customer retention rates, brands struggle to determine which channel offers better long-term economics. The question remains open: how should brands evaluate these competing channels when both present significant financial obstacles?

Brands need to constantly evaluate the economics between direct-to-customer channels (DTC) costs and marketplace commissions. While marketplaces drive margins to the ground with (>30-50% commissions), customer acquisition costs (CAC) on ad platforms are delivering ROAS < 0.5 at times. This implies that DTC survival is reliant on VERY HIGH repeat purchase rates (i.e. customer retention). How would you consider evaluating DTC and marketplaces, in context of higher CACs and dwindling customer retention rates?
