Managing multiple sales channels is exciting—but it can also feel overwhelming. Whether you’re selling on Shopify, Amazon, eBay, or all three, you probably already know how tricky it can be to keep stock levels accurate, track orders in one place, and avoid overselling.

This is where Linnworks steps in as a powerful solution. It allows sellers to bring everything under one roof—inventory, orders, shipping, and more. But the real value kicks in only when it’s integrated properly with your sales channels.

In this guide, we’ll walk you through how to connect Shopify, Amazon, and eBay with Linnworks and get your systems talking to each other smoothly—so you can focus on growing, not fixing.

Why Integration with Linnworks Matters

Before jumping into the how-to, let’s address the why. Here’s what you gain when Linnworks is fully connected to your sales channels:

• Centralized order processing
• Real-time inventory updates across platforms
• Automated product listings and updates
• Streamlined shipping workflows
• Reduced risk of overselling or underselling

In short, you manage your entire commerce operation from a single platform—without bouncing between tabs or spreadsheets.

1. Connecting Shopify to Linnworks

If you’re running your own storefront through Shopify, integrating it with Linnworks is a smart move. It enables automatic syncing of orders, inventory, and listings between your Shopify store and your backend system.

Here’s how to do it:

Step 1: Log in to Linnworks
Head to your Linnworks dashboard and go to Settings > Channel Integration.

Step 2: Add the Shopify Integration
Click Add New, search for Shopify, and select the option to install the integration.

Step 3: Authorize Access
You’ll be redirected to your Shopify admin to approve the connection. This step grants Linnworks access via API.

Step 4: Configure Settings
Once authorized, set your preferences—such as order sync frequency, stock updates, and listing controls.

Step 5: Run a Test Sync
Before going live, test the sync with a few SKUs to make sure inventory and orders are transferring properly.

2. Integrating Amazon with Linnworks

Selling on Amazon comes with high buyer expectations—and little room for inventory errors. That makes a real-time sync with Linnworks essential.

Steps to integrate:

Step 1: Go to Channel Integration in Linnworks
Navigate to Settings > Channel Integration, then click Add New and choose Amazon.

Step 2: Authorize the Connection
Log into your Amazon Seller Central account and grant Linnworks access. You’ll need credentials based on the region (e.g., Amazon.com or Amazon.co.uk).

Step 3: Set Fulfillment Preferences
Choose whether orders are fulfilled by Amazon (FBA) or by you (FBM). You can manage both within Linnworks.

Step 4: Adjust Sync Settings
Configure how often stock should update, what orders to import, and which SKUs should be tracked.

Step 5: Verify Mapping
Make sure your Amazon SKUs match those in Linnworks. You can use the Product Mapping tool to align them if needed.

3. Syncing eBay with Linnworks

eBay sellers often list products in a variety of formats—auctions, fixed-price, bundles—and across multiple geographies. Linnworks simplifies the complexity by bringing it all under one dashboard.

Integration process:

Step 1: Start with Channel Integration
Under Settings, click Add New Integration and choose eBay.

Step 2: Authorize the eBay Account
Sign in to your eBay seller account and approve the integration request.

Step 3: Choose Marketplace Region
eBay operates regionally, so select the marketplace (e.g., eBay.com or eBay.co.uk) that aligns with your selling focus.

Step 4: Configure Sync Options
Customize your settings for:

• Inventory sync frequency
• Listing imports or new listings
• Order status filters

Step 5: Map Listings to Products
Ensure your eBay listings are properly linked to products in Linnworks using the mapping tool.

Pro Tip: Avoid duplicating SKUs. Let Linnworks manage your listings directly if possible.

Best Practices for Multichannel Integration

Once all your platforms are connected, keep your operations running smoothly with these tips:

1. Use Consistent SKUs

It’s essential that the same SKUs are used across Shopify, Amazon, eBay, and Linnworks. This keeps inventory synced correctly and avoids duplicate records.

2. Automate Where Possible

Use automation rules in Linnworks to handle repetitive tasks—like tagging orders, assigning couriers, or setting priority levels.

3. Monitor Sync Logs

Linnworks provides logs that show integration status and errors. Check these regularly to catch any issues early.

4. Keep Listings Updated

If you edit a product in Shopify or Amazon, sync those changes back into Linnworks so your data stays current.

Bringing Shopify, Amazon, and eBay into one centralized system like Linnworks isn’t just about saving time. It’s about gaining control over your operations, reducing costly errors, and positioning your business to scale without the usual growing pains.

With the right setup, you’ll spend less time chasing stock issues or missed orders—and more time focusing on strategy, growth, and customer satisfaction.

Whether you’re running 500 orders a month or 5,000, seamless multichannel integration is the key to running lean and growing fast. And Linnworks makes that possible—if it’s implemented right.
