Best Marketplaces Apps for Shopify (2026)

List and sync products on Amazon, Walmart, eBay, Etsy and Shop.

5 apps ranked by the EcomGuide Score

Marketplace apps list your Shopify products on Amazon, Walmart, eBay and Etsy, then sync orders back into Shopify so you fulfill everything from one place. Done right, a marketplace becomes a second storefront with none of the traffic costs; done badly, you get oversells, suspended listings and double-shipped orders.

These apps differ most in how they map your catalog to each marketplace’s category and attribute requirements — Walmart and Amazon both reject listings with missing attributes. Inventory sync speed matters too: a marketplace order has to decrement Shopify stock within minutes, or a flash sale will oversell you on both channels.

How to choose a marketplaces app

  • Confirm the app supports the exact marketplaces and regions you sell in — "Amazon integration" often means amazon.com only.
  • Check whether existing marketplace listings can be linked to Shopify products, not just newly created ones.
  • Look for near-real-time inventory sync (minutes, not hourly) if you carry limited stock.
  • Factor marketplace fees into pricing rules — good apps let you set channel-specific markups automatically.
