For years, the central sales question in online retail was: marketplace or own shop — or both? That question now falls short. With the rise of AI agents, a third layer is emerging on which buying decisions are prepared and, increasingly, made: agentic commerce.

The good news: marketplace, own shop, and the agentic layer are not competitors but building blocks of one system. Marketplaces deliver reach, the own shop delivers margin, data, and customer relationships — and the agentic layer becomes the new discovery and transaction layer on top. This whitepaper shows how individual channels become a connected sales system.

## What's inside

- **The limits of pure strategies:** Why marketplace-only means margin erosion, data loss, and platform dependency — and why shop-only becomes a traffic risk in a world where AI takes over discovery.
- **The real break:** How discovery and decision shift to a layer that belongs to neither the marketplace nor the shop — and what that means for visibility.
- **The channel network model:** Marketplace, own shop, customer portal, and agentic commerce with clear roles — and how they reinforce rather than cannibalise each other.
- **The shared foundation:** Why the network only holds on data quality, clean system integration, and end-to-end measurability — including AI referral tracking.
- **The F.O.C.U.S. roadmap:** How channel thinking becomes a system — prioritised by impact, not hype.

## Who this whitepaper is for

Merchants, e-commerce leads, and executives who sell on marketplaces and in their own shop today and want to know how to prepare their channels for the new, AI-driven discovery layer — without blind agentic actionism.

## The key figures

According to McKinsey, 38 percent of European consumers already use AI for product and brand discovery; by 2030, agentic commerce could orchestrate a global volume of three to five trillion US dollars. A ten-question self-check at the end shows where your channel system stands today.
