Double Your Sales by Integrating BigCommerce with Amazon

Why Every Small Business Owner Should Care About BigCommerce Amazon Integration

BigCommerce Amazon integration connects your BigCommerce store directly to Amazon's marketplace, letting you manage listings, inventory, and orders from one place.

Here's how it works at a glance:

1. Connect your Amazon Professional Seller account to BigCommerce via Channel Manager or a third-party app

2. Sync your product catalog, pricing, and inventory across both platforms automatically

3. Receive orders from Amazon directly inside your BigCommerce dashboard

4. Fulfill orders through your own warehouse or Amazon's fulfillment network (MCF)

5. Track inventory in real time to prevent overselling on either channel

Amazon controls roughly 50% of the U.S. ecommerce market and pulls in over 2 billion monthly visitors every month. If your products aren't listed there, a competitor's are. For small business owners already running a BigCommerce store, adding Amazon as a sales channel isn't just a growth tactic — it's one of the fastest ways to reach more buyers without rebuilding your entire operation. Research shows that merchants who add even one new sales channel grow 38% faster. Add two channels, and that number can jump to 120% or more.

The challenge? Getting the two platforms talking to each other correctly — without overselling, listing errors, or hours of manual work.

I'm Carlos Cortez, senior consultant at S9 Consulting, and I've personally scaled an e-commerce distribution business to over $18 million in revenue by building tightly integrated sales and fulfillment systems — including BigCommerce Amazon integration workflows — from the ground up. In this guide, I'll walk you through exactly how to set it up, avoid the common pitfalls, and make the most of Amazon's reach.

Why Multi-Channel Selling is Essential in 2026

As we navigate through 2026, the retail landscape is more competitive than ever. Relying on a single storefront is like opening a beautiful boutique on a deserted island. You might have the best products and the sleekest web design, but if nobody passes by, your sales will remain flat.

Diversification is the name of the game. When you establish a multi-channel presence, you meet your customers where they already are. Consumers don’t always start their shopping journey on search engines; in fact, more than half of all product searches now begin directly on marketplace platforms.

By executing a strategic Ecommerce Marketplace Integration, you can capture this high-intent traffic. Our team at S9 Consulting operates as a dedicated Ecommerce Digital Transformation Agency to help businesses bridge these platform gaps, ensuring you don't miss out on the massive growth that comes with multi-channel expansion.

The Power of Amazon's Global Reach

With over 2 billion monthly visitors, Amazon is an absolute juggernaut. It functions not just as a store, but as a massive search engine specifically built for buying. Listing your products on Amazon exposes your brand to millions of customers who might never have found your standalone website.

Furthermore, Amazon's Global Selling Program allows you to expand your footprint internationally with ease. This massive influx of visibility acts as a powerful top-of-funnel driver. By utilizing smart E-commerce Funnel Optimization strategies, you can leverage Amazon for initial customer acquisition and then nurture those relationships to build long-term brand loyalty on your native BigCommerce site.

What are the main benefits of a bigcommerce amazon integration?

When you link these two powerhouses, you get the best of both worlds: the brand control and higher margins of your own site, combined with the sheer volume of Amazon.

Here are the primary advantages of setting up a robust connection:

• Centralized Management: You no longer need to log into two separate dashboards to manage your business. You can view, edit, and manage your product details directly from your BigCommerce control panel.

• Automated Operations: Manual data entry is a recipe for errors. The integration automates order imports, shipping updates, and stock adjustments.

• Eliminate Overselling: There is nothing worse than having to cancel a customer's order because you ran out of stock. Real-time synchronization keeps your inventory levels aligned across both channels.

• Streamlined Fulfillment: Whether you ship orders yourself or use Amazon’s extensive logistics network, the integration keeps tracking numbers and fulfillment statuses perfectly in sync.

Step-by-Step Guide to Setting Up Your BigCommerce Amazon Integration

In the past, BigCommerce offered a native Amazon integration. However, that feature was sunsetted to make way for more robust, specialized third-party integration applications accessible directly within the BigCommerce Channel Manager. Today, setting up your bigcommerce amazon integration is straightforward, provided you follow the correct sequence.

For a complete overview of the process, you can read our comprehensive BigCommerce Amazon Marketplace Integration Guide. Additionally, the technical breakdown provided in How to Integrate BigCommerce With Amazon is an excellent resource for understanding the underlying mechanics.

Let's walk through the exact steps to get connected.

Step 1: Meet the Prerequisites and Account Requirements

Before you click a single button in BigCommerce, you must ensure your accounts are fully prepared. Amazon has strict entry requirements, and failing to meet them will halt your integration before it even starts.

1. Amazon Professional Seller Account: You must have an active Professional Selling Plan, which costs $39.99/month. Individual seller accounts do not have API access, meaning they cannot connect to external platforms like BigCommerce.

2. Valid Product Identifiers (GTINs): Amazon requires standard product identifiers such as UPCs, EANs, or ISBNs. Ensure your BigCommerce product catalog has these fields filled out accurately. If you manufacture your own white-label products, you must apply for a GTIN exemption through Amazon Seller Central first.

3. Category Approval: Certain categories—such as Fine Art, Jewelry, or Watches—require specific approval from Amazon before you can list products. Make sure your account is approved for your specific categories.

4. Currency and Location Settings: Your BigCommerce store’s default currency must match the target Amazon marketplace (e.g., USD for Amazon.com), and your shipping settings must support shipping to that region.

Managing these moving parts can be daunting. If you need help getting your products retail-ready for the marketplace, our specialized services in E-commerce Management for Amazon Sellers can ensure your catalog meets all of Amazon's strict requirements.

Step 2: Connect via BigCommerce Channel Manager

Once your prerequisites are checked off, it is time to establish the connection:

1. Log into your BigCommerce control panel.

2. Navigate to Channel Manager on the left-hand menu.

3. Click on + Create Channel.

4. Under the Marketplaces section, select Amazon.

5. Choose your preferred integration tool (such as LitCommerce, Codisto, or MapMyChannel) to act as the bridge.

6. Click Connect and follow the prompts to log into your Amazon Seller Central account, granting the necessary API permissions to authorize the app.

Step 3: Map Categories and Sync Products

With the bridge established, you must teach the two platforms how to talk to each other regarding your product catalog.

• Category Mapping: Amazon’s category structure (taxonomy) is incredibly detailed. You must map your BigCommerce categories to the corresponding Amazon categories. Always map to the deepest possible subcategory to maximize your visibility in Amazon's search filters.

• Bulk Mapping: Most integration apps offer bulk mapping features. Use these to map entire collections of products at once rather than doing it item-by-item.

• SKU Matching: If you already have active listings on Amazon, the integration software will attempt to automatically match them to your BigCommerce products using the SKU or UPC. Ensure your SKUs match exactly on both platforms to avoid duplicate listings.

Step 4: Resolve Listing Rejections and Sync Delays

It is completely normal to encounter a few errors when first pushing products from BigCommerce to Amazon. Here is how to handle the most common ones:

• Missing Product Type: This occurs when the category mapping is incomplete. Go back to your integration settings and ensure the specific Product Type attribute is assigned.

• Invalid UPC/GTIN: Double-check that your UPC codes are valid GS1 identifiers. If you have a GTIN exemption, make sure the brand name on your BigCommerce product matches the approved exemption brand name exactly—down to the capitalization.

• Image Processing Delays: New listings typically appear on Amazon within an hour, but product images can take up to 24 hours to fully render. Don't panic if your listings look bare at first.

• Pending Listings: If a listing remains in "pending" status for too long, check your Amazon Seller Central performance notifications to ensure your account is not facing any temporary policy holds or verification requests.

Advanced Fulfillment and Inventory Management

Once your store is connected, you need a clear strategy for how you will fulfill orders and keep your stock counts accurate. You have a few options, and choosing the right mix is vital to maintaining your seller rating.

Feature	Merchant Fulfillment (FBM)	Fulfillment by Amazon (FBA)	Multi-Channel Fulfillment (MCF)
Who Ships It?	You (or your local 3PL)	Amazon	Amazon
For Which Channel?	BigCommerce & Amazon	Amazon Only	Non-Amazon Channels (BigCommerce)
Packaging	Your own branded boxes	Amazon branded boxes	Unbranded packaging available
Prime Badge?	No (unless Seller-Fulfilled Prime)	Yes	Yes (on BigCommerce via Buy with Prime)

Keeping these systems running smoothly requires hands-on oversight. Our team provides comprehensive E-commerce Management to handle these operational complexities for you, letting you focus on scaling your brand.

How does the bigcommerce amazon integration handle inventory sync?

The integration software works by setting BigCommerce as your "source of truth." When an item sells on your BigCommerce site, the integration automatically decrements the stock levels and pushes the updated quantity to Amazon in real time. The same happens in reverse when an item sells on Amazon.

To protect your business during peak shopping seasons, we highly recommend setting up an inventory buffer. For example, if you set a buffer of "2," the integration will tell Amazon you are out of stock when your actual inventory level drops to 2. This prevents double-selling if a product is purchased on both channels simultaneously before the API can sync.

Leveraging Amazon Multi-Channel Fulfillment (MCF)

You don't have to pack every box yourself. With Amazon Multi-Channel Fulfillment (MCF), you can store your inventory in Amazon’s fulfillment centers and use them to ship orders placed on your BigCommerce website.

By installing the official MCF app on BigCommerce, you can automate this process entirely. When a customer buys a product on your site, the order is routed to Amazon, which picks, packs, and ships the item in unbranded packaging. Tracking details are automatically fed back into BigCommerce to keep your customer informed. Best of all, eligible merchants can save up to 15% on fulfillment fees through Amazon's Preferred Pricing program.

For setup instructions, refer to the MCF App for BigCommerce User Guide.

Boosting Conversions with Buy with Prime

One of the most exciting developments for BigCommerce merchants is the native integration of Buy with Prime. This feature allows you to place the trusted Prime badge directly on your BigCommerce product pages.

When Prime members shop on your site, they can checkout using their saved Amazon shipping and payment details, enjoying the fast, free delivery they expect. Data shows that adding Buy with Prime can increase shopper conversions by an average of 25% by removing checkout friction and building instant trust.

Frequently Asked Questions

Can I use Amazon Pay on my BigCommerce store?

Yes! Amazon Pay is an excellent way to reduce cart abandonment. It allows your customers to use the payment methods and shipping addresses already stored in their Amazon accounts to complete checkouts on your BigCommerce site.

Setting it up is simple: navigate to your BigCommerce Payment settings, locate Amazon Pay under digital wallets, and connect your merchant credentials. For a full walkthrough, check out the official guide on Connecting with Amazon Pay.

Does the integration support international marketplaces?

Yes. Most modern integration apps support multi-channel, multi-region setups. You can connect your BigCommerce store to Amazon marketplaces in Europe, Canada, Japan, and beyond. However, you must ensure your product listings, pricing, and shipping rates are localized for each specific region's currency and regulations.

What happens to my existing Amazon listings during integration?

Your existing Amazon listings will not be deleted or overwritten. When you connect your integration app, it will perform a discovery scan of your Amazon Seller account. By matching the SKUs or UPCs, the app will link your existing Amazon listings to your BigCommerce products, preserving your sales history, search rankings, and reviews.
