Amazon Seller Sync
Amazon Seller Sync is an embedded Shopify app that connects your Shopify store to Amazon and keeps the two in step. You install it from the Shopify App Store, connect your Amazon Seller Central account, and run everything from inside Shopify Admin — there is nothing to install on your computer.

What it does
The app brings the whole Amazon workflow into Shopify:
- Product Mapping — link Shopify variants to Amazon ASINs and pull live Amazon prices, the Buy Box status, and price history into Shopify.
- Product Sync — publish and manage Amazon listings from Shopify, with attributes, category types, fee estimates, and AI-assisted copy, per marketplace.
- Buy Box Repricer — automatically win the Buy Box within safe, Fair-Pricing-compliant floor and ceiling bounds.
- Inventory Sync — see FBA availability and push FBM stock from Shopify to Amazon per marketplace.
- Fulfilment by Amazon (MCF) — let Amazon fulfil your Shopify orders, with multi-market routing, tracking write-back, and an auto-reassign fallback.
- Amazon Buy Button — add an "Available on Amazon" button to your storefront so shoppers can buy on Amazon.
- Analytics — Buy Box win-rate over time, suggested FBA restock, and a margin report (price minus fees minus cost), exportable to CSV.
Who it is for
Amazon Seller Sync is for Shopify merchants who also sell on Amazon and want a single place to keep prices, stock, listings, and fulfilment aligned across both channels. It suits everyone from a single-market seller who just wants live Amazon prices on their product pages, up to a multi-account, multi-marketplace operation that publishes and reprices thousands of listings.

The app has a left-hand navigation inside Shopify Admin. The most-used tools sit at the top, followed by insights and account settings:
