How to connect Shopify to Amazon (and keep everything in sync)

In 2021, Shopify removed its native Amazon sales channel, and the two platforms do not sync inventory out of the box. That means you need a third-party integration to connect them.

Connecting the platforms gives Shopify merchants access to one of the world's largest online marketplaces while keeping their existing store at the center of their ecommerce operations. Amazon's net sales topped $716.9 billion in 2025, with independent third-party sellers accounting for more than 60% of paid units sold. Shopify merchants, meanwhile, generated $378.4 billion in gross merchandise volume during the same year.

In this article, we'll walk through exactly how to connect Shopify to Amazon and choose the right integration tool to set up listings, inventory, and order management.

Key Takeaways

• Connecting Shopify to Amazon requires a third-party integration because the two platforms do not sync listings, inventory, and orders automatically.
• You need a Professional Amazon Seller account, a paid Shopify plan, verified seller credentials, clean product data, and a fulfillment strategy.
• Shopify Marketplace Connect suits smaller sellers, while dedicated Amazon apps offer more marketplace-specific features and multichannel eCommerce platforms support larger catalogs.
• Channable lets you import your Shopify catalog, adapt product data to Amazon's requirements, publish listings, and keep prices, stock, and orders synchronized.

Why Shopify sellers add Amazon as a sales channel

Your Shopify store is where you build brand loyalty and control the customer experience. But you have to drive every visitor yourself through paid ads, SEO, social media, and email marketing.

That's why Shopify sellers add Amazon as a sales channel because it puts their products in front of millions of ready-to-buy shoppers they can't reach through their Shopify store alone.

According to Shopify's own data, customer acquisition costs range from $21 in low-competition categories to $127+ in competitive verticals like health and beauty. Amazon, by contrast, brings the traffic to you.

• Built-in traffic you don't pay to acquire: Amazon attracts roughly 2.7 billion visits every month. Nobody visits Amazon searching for your brand. But they're already there, wallet open, searching for products just like yours.
• Trust and discoverability: Amazon's search engine surfaces relevant products fast, and shoppers already trust the platform. That means your existing products can get discovered by customers who would never have found your Shopify store.
• Prime eligibility drives conversions: According to Amazon, adding Prime as a purchase option increases shopper conversion by an average of 25%. The Prime badge signals legitimacy and delivery reliability, which reduces purchase hesitation and boosts sales.
• Fulfillment without logistics planning: Fulfillment by Amazon (FBA) handles storage, packing, and shipping for you. That means faster delivery, fewer fulfillment errors, and more time to focus on growing your business instead of managing logistics.
• New customer acquisition: Many brands use Amazon to attract first-time buyers, then encourage them to purchase directly from their Shopify store for better margins on repeat sales.

What Amazon sellers need before setting up a Shopify integration

Amazon sellers who set up the Shopify integration without checking their accounts, product data, and fulfillment settings often run into connection errors, listing rejections, and sync failures.

Here's what you need before connecting Shopify to the Amazon marketplace.

• An Amazon Professional Seller account: Individual accounts don't support Amazon Marketplace Web Service (MWS), now termed Selling Partner API (SP-API), which is the API that the Marketplace Connect app uses to manage your Amazon listings and inventory. The Professional plan costs $39.99 per month, plus referral fees and any applicable fulfillment fees.
• An active Shopify store subscription: Your Shopify store must be active. Smaller sellers with simple catalogs may use Shopify Marketplace Connect, which requires a paid Shopify plan. Sellers with larger or more complex catalogs may use a third-party integrator, which may require a specific Shopify plan and charge its own subscription fee.
• A verified Amazon seller account: Your Amazon seller account must be approved and eligible to sell before you can connect it to Shopify.
• Permission to access your Amazon account: When you connect Amazon through Shopify Marketplace Connect, you'll be asked to sign in and authorize the app to manage your listings, orders, and inventory.
• Payment method and bank account: Amazon pays you directly for orders placed on its marketplace. You need a payment method and bank account connected to your Amazon seller account to receive payouts.
• Shipping rates configured: Amazon has specific shipping requirements depending on your fulfillment method, whether you self-fulfill orders or use Fulfillment by Amazon (FBA).
• Clean product data with valid identifiers: Your Shopify product listings need to be ready for Amazon. That means accurate inventory counts, clean and canonical SKUs that map to existing Amazon listings, and valid product identifiers like GTINs or UPCs. Amazon uses these identifiers to match your products to existing listings in its catalog. If your data is incomplete or inconsistent, Amazon may reject your listings.
• A fulfillment strategy: Decide upfront whether you'll self-fulfill orders from your own warehouse or use Amazon FBA. You can compare Amazon FBA and FBM to determine which model better suits your products, margins, and operational capacity. FBA can make your products Prime eligible, but it requires sending inventory to Amazon's fulfillment centers. Your choice affects how the integration manages orders and inventory.
• Store policies visible: Your return, refund, and shipping policies need to be visible on Amazon, according to Amazon's seller requirements. Amazon enforces its own customer service guidelines, so make sure your policies align.

3 Options for Shopify Amazon marketplace integration

Since Shopify removed its native Amazon sales channel, you need to choose a third-party solution. There are three main paths, each designed for different catalog sizes and business complexity.

1. Shopify Marketplace Connect

Shopify Marketplace Connect is Shopify's official app for connecting your store to online marketplaces like Amazon, eBay, Walmart, and Etsy. It can be installed from the Shopify App Store and managed within your Shopify admin. The first 50 marketplace-synced orders each month are free. After that, Shopify charges 1% per additional synced order, capped at $99 per month.

What it does:

• Syncs product listings, inventory, and orders across multiple marketplaces from one dashboard
• Supports real-time inventory sync to prevent overselling
• Handles order fulfillment data back into Shopify
• Works with Amazon FBA and FBM orders

While Marketplace Connect handles basic sync well, it has limitations at scale. It doesn't offer marketplace-specific pricing rules or the ability to customize listings per channel. If your catalog is complex or you sell across many online marketplaces, you'll hit a ceiling quickly.

2. Dedicated Amazon channel apps

These are third-party apps built specifically for the Shopify-Amazon connection. Examples include CedCommerce Amazon Channel, CS Amazon Integration & Sync, and Amazon Connectr & FBA Sync.

What they do:

• Focus exclusively on Amazon, not a multi-marketplace tool
• Real-time inventory, order, and price sync
• Bulk listing creation and editing tools
• Some include FBA/MCF integration for order fulfillment

However, these apps typically support only one marketplace at a time. If you later want to expand to eBay, Walmart, or TikTok Shop, you'd need a separate app for each, which means managing multiple dashboards, multiple syncs, and potentially conflicting inventory data.

3. Multichannel eCommerce platforms

Multichannel eCommerce platforms take a different approach. Instead of syncing Shopify directly to Amazon, they sit between your Shopify store and all your sales channels.

For example, Channable connects your Shopify store to Amazon, eBay, Google Shopping, Meta, and 3,000+ other channels from a single dashboard. You import your full Shopify catalog into Channable, then use IF-THEN rules to filter, modify, and enrich product data to meet each channel's requirements.

You can optimize titles, prices, and attributes for each marketplace. Inventory and orders sync back to Shopify in real-time. And it supports smart repricing to win the Amazon Buy Box.

How to link Shopify to Amazon with Channable in 5 steps

Managing Amazon through Shopify becomes harder as your catalog grows. Product data, listings, prices, stock, and orders all need to stay accurate across both platforms.

Channable automates these workflows, helping you reduce manual updates, prevent listing errors, and scale your Amazon sales more efficiently.

Here are five ways Channable simplifies Shopify-to-Amazon selling.

Step 1. Build Amazon listings from the product data you already manage in Shopify

Before Channable can automate your Amazon listings, it needs access to the product information you already manage in Shopify. When you connect Channable to your Shopify store, Channable imports your Shopify product data, including titles, descriptions, images, variants, SKUs, prices, stock levels, and product identifiers. This creates one central feed that you can prepare for Amazon without rebuilding every listing from scratch.

Channable then lets you clean, enrich, and map that Shopify data to Amazon's requirements. You can apply rules across the complete catalog instead of editing products one at a time.

For example, you could automatically add brand names to titles, map Shopify colors to Amazon-approved values, exclude products that are out of stock, or use different descriptions for Amazon.

Step 2: Turn Shopify data into Amazon-ready listings at scale

Not every Shopify product needs a new Amazon listing. Some products already have an Amazon Standard Identification Number (ASIN), while others need a complete product page. Sending the wrong type of data can create duplicate listings, trigger product-matching errors, or stop products from going live.

Channable helps you separate these products and choose what Amazon needs from each one:

• Offer and product: Use this for products that are new to Amazon or when you need to update listings in bulk. Channable sends the product content alongside your price, stock, condition, and fulfilment details.
• Offer only: Use this when the product already exists in Amazon's catalog. With Amazon product matching, Channable checks identifiers such as the EAN, GTIN, or UPC against Amazon's catalog and connects the Shopify product to the correct ASIN. You then send only your price and stock instead of submitting product information that may conflict with the existing listing.
• Product only: Use this when you want to update listing content, such as the title, description, images, or attributes, without changing the offer details.
  
  Once you choose the right listing type, you can turn your Shopify data into the format Amazon expects. Channable lets you standardize titles and brand names, assign products to Amazon categories, map identifiers, and add category-specific details such as material, size, quantity, country of origin, and relevant compliance information.

You can also use Amazon Bulk Mapping to apply shared attributes across several categories instead of mapping the same fields repeatedly. For example, a fashion retailer can map brand, color, size, and material across T-shirts, jeans, and jackets, while still adding the unique fields required for each category.

Step 3: Connect Channable to Amazon Seller Central

Once your product data is ready, Channable connects to your Professional Amazon Seller account through the Selling Partner API. This lets you send new product listings, add offers to existing products, and update product content without uploading files or editing listings individually in Seller Central.

For larger catalogs, it also helps to separate product content from commercial updates:

• Product channel: Sends titles, descriptions, images, categories, and other product attributes
• Offer channel: Sends price, stock, condition, shipping, and fulfilment information

This keeps important price and inventory updates moving quickly, even when Amazon takes longer to process heavier product-content changes.

Step 4: Publish your Amazon listings

Once Channable is connected to Seller Central, you can publish new product pages, add offers to existing Amazon listings, or update product content based on the listing type you selected earlier.

You can use Channable Rules to control which products are ready to go live and hold back products that are missing important information. This can also help you make more profits on Amazon.

For example, you can automatically:

• Exclude products without a valid EAN, GTIN, or UPC
• Hold back products that still need Amazon category approval
• Publish only products that are in stock
• Send complete product data for new listings and only price and stock for existing ASINs
  
  A seller with 5,000 Shopify products, for example, may have 4,200 products ready for Amazon and 800 with missing identifiers or category data. Instead of letting those 800 products fail during publishing, Channable can exclude them until the missing information is fixed.

You can also publish a smaller product group first and review Amazon's feedback before sending the full catalog. Once the setup works as expected, you can apply the same rules across the remaining products. This reduces the risk of duplicate listings, rejected products, and the same error affecting thousands of items.

Step 5: Keep Amazon orders and Shopify inventory in sync

Once your Amazon listings are live, the next challenge is keeping inventory and order information accurate across Shopify and Amazon. Channable automatically syncs Amazon orders, stock changes, shipment updates, and tracking details.

Amazon orders then flow back into your existing eCommerce workflow. You can manage them alongside Shopify orders, even if you're using different fulfillment methods like merchant-fulfilled, FBA, or Multi-Channel Fulfillment.

The key benefit is a single, consistent view of inventory and order status, so Amazon becomes an extra sales channel on top of Shopify.

Selling on Amazon is just the start. Expand across channels

Selling on Amazon is one way to tap into a huge marketplace audience, but it's still just one channel in a broader ecommerce landscape. Many Shopify merchants sell on multiple online marketplaces, like eBay, Walmart, TikTok Shop, and regional platforms, to reach different customer segments and reduce their dependence on any single platform.

Channable helps you with this multichannel growth. You import your Shopify catalog once and use the Marketplace Integrator to keep your listings, inventory, and orders in sync across channels.

As your eCommerce business expands, Channable makes it easier to add and scale new channels without rebuilding your workflow every time.
