marketplace-strategy

What problem does it solve?

This Skill prevents an ecomm operator from making marketplace decisions that quietly destroy DTC margin (or from skipping marketplaces when buyer behavior demands presence) by forcing an economics-first, SKU-level evaluation.

Core Features & Use Cases

• Marketplace-fit gating: Scores Amazon (1P/3P), Walmart Marketplace, Target Plus, and niche alternatives against margin, AOV, and catalog fit to avoid reflexive listing.
• All-in unit economics: Calculates the fee load (referral, fulfillment, storage, ads, returns, promos) against gross margin at the SKU level, then classifies profitability.
• Buy Box and presence mechanics: Guides actions around price, fulfillment choice, performance metrics (e.g., ODR), inventory coverage, and account standing to protect conversion outcomes.
• SKU portfolio channel plan: Assigns hero, discovery, bundle, and loss-leader SKUs to DTC or marketplaces so listings subsidize DTC instead of replacing it.
• Cannibalization measurement plan: Defines how to estimate DTC impact via geo holdouts, before/after time-series, and customer attribution overlap.

Quick Start

Ask for the decision on whether to list on Amazon based on your current DTC revenue, gross margin, AOV, and SKU-level economics, and include a measurement plan to estimate cannibalization after launch.
