Multichannel & Marketplace Selling Strategy

Helps you sell one catalog in many places — Amazon, eBay, Etsy, Walmart, TikTok Shop, Google Shopping, Facebook/Instagram — from a single store backend, without the inventory, listing, and order chaos that breaks when you add channels manually. This is a tool-agnostic strategy skill: it frames the decisions (which channels, which tool, how to not oversell) across the whole category, then hands off to a specific platform skill for deep config.

Step 1 — Gather context

If references/learnings.md exists, read it first for accumulated knowledge.

Ask the user (lead with a best-effort answer if they've already told you most of this):

1. What's the decision?
   • A) Which channels to expand onto (Amazon vs eBay vs Etsy vs TikTok Shop vs Google/Meta)
   • B) Which tool — native builder feature vs a dedicated channel manager, and which one
   • C) Fixing sync — inventory/orders not matching across channels, overselling
   • D) Listings rejected/not live on a marketplace (identifiers, categories, policies)
2. What's your store backend (source of truth)? Shopify · WooCommerce · Wix · BigCommerce · Squarespace · Square · a spreadsheet/ERP. This decides which tools even connect.
3. Catalog size & velocity? Number of SKUs/variations, and how fast the fast-movers sell (drives the oversell-risk and tool tier).
4. What do you sell? New retail/DTC · handmade/vintage (Etsy/eBay) · resale/thrift (Poshmark/Mercari/Depop — different tool class) · branded products with GTINs.
5. Stage/team? Solo/maker · small team · scaling. Most makers want the lightest tool that won't oversell.
