A multi-marketplace seller dashboard for solo sellers and small teams shipping on Amazon, Etsy, eBay, and Mercari simultaneously. Inventory stays in sync; an AI agent optimizes each listing for the platform's algorithm; orders route into one fulfillment queue.
What's Included
- Inventory Table: Master SKU list with per-marketplace stock and last-synced timestamp
- AI Listing Optimizer: Reads your product → drafts Amazon title (keywords + bullets), Etsy tags + photos, eBay item specifics — tuned per platform's algorithm
- Order Routing: Inbound orders from all marketplaces hit one queue with priority sort by ship-by date
- Profit-Per-Order Tracker: Auto-calculates margin after platform fee, shipping, materials
- Refund + Review Agent: Drafts responses to negative reviews; routes refund requests to one folder
- Multi-Marketplace Sync: Stock decrements across all channels when one sells
Why This Template Wins
- Stockout prevention across 4 marketplaces. When one Amazon order sells your last unit, Etsy + eBay listings flip to out-of-stock simultaneously. No more selling phantom inventory.
- AI listing optimization that respects platform algorithms. Amazon rewards keyword-rich titles; Etsy rewards tag breadth; eBay rewards detailed item specifics. The agent tunes per platform.
- One fulfillment queue. Pick-and-pack doesn't care which platform sold the unit — they just need the ship-by date and address.
