If you want to know how to sell on Amazon through Shopify in 2026, the key change to understand first is that Shopify retired its native Amazon channel in 2023. You now connect both Amazon and eBay through an integration app, with Shopify Marketplace Connect being Shopify's own option, and you keep Shopify as your single source of truth for products, inventory, and orders. The marketplaces become extra storefronts that pull from that one catalog. Here is how the connection works, how to run Shopify and Amazon side by side, and how to add eBay to the same setup.
Key takeaways
- To sell on Amazon through Shopify, install a marketplace integration app, link your Amazon Seller Central account, and map your Shopify products to Amazon listings.
- Selling on Shopify and Amazon at the same time works best when Shopify is your source of truth and Amazon is your demand channel, each doing the job it is good at.
- To sell on eBay through Shopify, use the same integration approach: connect eBay with a marketplace app, sync your catalog, and manage eBay orders inside Shopify.
How to Sell on Amazon Through Shopify
To sell on Amazon through Shopify, install a marketplace integration app, link your Amazon Seller Central account, and map your Shopify products to Amazon listings. Since the native channel is gone, the setup looks like this:
- - Install a connector. Shopify Marketplace Connect links Amazon (and eBay, Walmart, and Target Plus) to your store from one dashboard. Third-party apps like Salestio or CedCommerce do the same job.
- - Meet the requirements. You need a Professional Amazon Seller account, since the Individual plan will not connect to these apps.
- - Map and match. Link existing listings by SKU or create new ones, and make sure titles, categories, and identifiers meet Amazon's rules.
- - Sync inventory both ways. Set a stock buffer so a sale on either channel updates the other and you never oversell.
The point of connecting through Shopify is control. You manage one catalog, and Amazon becomes a reach channel that never contradicts your store.
How to Sell on Shopify and Amazon Together
Selling on Shopify and Amazon at the same time works best when Shopify is your source of truth and Amazon is your demand channel, each doing the job it is good at. Split the roles like this:
1. Shopify owns the brand and margin. It is your owned storefront, your customer relationship, and your best profit per order because no marketplace takes a cut of the sale. 2. Amazon owns the reach. It puts you in front of millions of ready buyers who would never find your standalone store. 3. The connector keeps them honest. Inventory, pricing, and order data sync so the same unit is never sold twice and your numbers always match.
Run them as one operation, not two competing stores. Use Amazon to capture buyers you cannot reach alone, then use Shopify's owned email and retargeting to bring repeat purchases back to your higher-margin store.
How to Sell on eBay Through Shopify
To sell on eBay through Shopify, use the same integration approach: connect eBay with a marketplace app, sync your catalog, and manage eBay orders inside Shopify. eBay suits certain products especially well:
| eBay strength | Best for | Why it works |
|---|---|---|
| Auction and fixed-price | Collectibles, rare, and used items | Buyers expect and search for them here |
| Global buyer base | Cross-border reach | Built-in international shipping programs |
| Lower barrier to list | Testing new products | Quick to list without brand gating |
| Category demand | Parts, electronics, niche goods | Strong intent in specific categories |
Shopify Marketplace Connect supports eBay alongside Amazon, so both marketplaces run from the same dashboard. List once in Shopify, publish to both, and let the connector keep stock and orders in sync so you are never managing three separate inboxes.
