How to Connect Shopify with eBay in Australia (Step-by-Step Guide)
Jeff A.
If you're already running a Shopify store in Australia, selling on eBay at the same time is one of the quickest ways to reach more buyers without building a second business from scratch. eBay has a large and active customer base in Australia, and many of them shop exclusively on the marketplace. They won't find your Shopify store on their own.
The challenge is managing both channels at once. Listing products on eBay manually, updating stock levels in two places, and reconciling orders from two different systems is the kind of admin that turns a promising sales channel into a daily headache.
The good news is that connecting Shopify with eBay can be automated. In this step-by-step guide, we'll walk you through how the integration works, what you need to get started, and how to keep your inventory and orders in sync across both platforms.
Why Australian Businesses Are Selling on eBay and Shopify Together
eBay in Australia continues to attract significant traffic. For Australian ecommerce businesses, it offers exposure to buyers that a standalone Shopify store may not easily reach, particularly in categories like electronics, auto parts, sporting goods, collectibles, and general merchandise.
More importantly, searches for eBay-related ecommerce terms in Australia have surged. "Ebay businesses" as a search term is up over 900% year on year, indicating a growing number of sellers actively looking to start or scale their eBay operations. For Shopify merchants, this is an opportunity to capture that demand using inventory they already have.
Key reasons Australian businesses run Shopify and eBay together:
- Broader reach. eBay brings buyers who don't shop on brand websites
- Second income stream. Clearance stock, excess inventory, or additional SKUs can move on eBay faster
- Lower acquisition costs. eBay buyers are already in purchase mode; you're not paying for ad clicks
- Marketplace trust. Some buyers feel more confident purchasing through eBay's buyer protection system
The catch is that running two channels separately doubles your workload. Integration removes that friction.
What You Need Before You Start
Before connecting Shopify and eBay, make sure you have:
- A Shopify store with your products already set up (titles, descriptions, images, pricing, and inventory quantities)
- An eBay seller account registered in Australia. If you don't have one yet, go to ebay.com.au and create a business seller account
- An eBay store subscription (recommended for businesses listing more than a small number of items, as it reduces final value fees and provides a professional storefront)
- Product information ready to map to eBay's category and item specifics requirements — eBay requires more structured product data than Shopify
- An integration tool or connector to manage the sync between the two platforms
How to Connect Shopify with eBay: Step by Step
Step 1: Choose Your Integration Method
There are a few ways to connect Shopify and eBay. The right option depends on your catalogue size, order volume, and budget.
Option A: Shopify's native eBay sales channel Shopify previously had a native eBay channel, but its availability has changed over time. Check the Shopify App Store for the current status of first-party eBay integration.
Option B: Third-party apps via the Shopify App Store Apps like Codisto (now part of Linnworks), CedCommerce eBay Integration, or similar tools connect Shopify to eBay and handle product sync, inventory, and order management.
Option C: A dedicated integration platform like Web Ninja Web Ninja provides a purpose-built connector for Australian ecommerce businesses that links Shopify to eBay and also connects to accounting software like MYOB, Xero, or QuickBooks. This is the most complete option if you also want orders and financials to flow automatically into your accounting system.
For most Australian businesses that are serious about multi-channel selling, Option C gives you the cleanest setup because it handles not just the Shopify-eBay connection but also the back-office accounting sync that you'll eventually need anyway.
Step 2: Connect Your eBay Account to the Integration Tool
Once you've selected your integration method, you'll need to authorise the connection between your eBay account and the tool.
This typically involves:
- Logging into your integration tool or connecting platform
- Navigating to the eBay connection settings
- Clicking "Connect eBay account" and being redirected to eBay to grant permissions
- Confirming the authorisation so the tool can read and write to your eBay listings and orders
This is an OAuth-based authorisation process, so you're granting the integration tool secure access without sharing your eBay password with a third party.
Step 3: Map Your Shopify Products to eBay
Not every product in your Shopify store needs to be listed on eBay. You can choose which products to sync.
When setting up the integration, you'll map your Shopify products to eBay listings. This involves:
- Selecting which products to push to eBay. You can do this individually or by collection.
- Setting eBay-specific pricing. You may want to price items differently on eBay to account for eBay's fees (typically 10–15% depending on category). Most integration tools let you set a markup percentage or flat fee on top of your Shopify price.
- Adding eBay item specifics. eBay requires structured data fields (brand, model, condition, size, etc.) that Shopify doesn't enforce. You'll need to fill these in to comply with eBay's listing requirements.
- Setting eBay categories. Each product must be mapped to the correct eBay category for your listings to go live.
- Configuring dispatch time and postage options. Set your handling time and the shipping services you offer on eBay (Australia Post, Sendle, etc.).
Step 4: Sync Your Inventory
Once your products are mapped, the integration will sync your inventory levels between Shopify and eBay. When a product sells on Shopify, the available quantity on eBay updates automatically. When a product sells on eBay, your Shopify inventory decrements.
This prevents overselling, which is a common and costly problem when managing two channels manually. Without inventory sync, it's easy to sell the last unit on Shopify while an eBay sale is pending, leaving you unable to fulfil one of the orders.
Make sure your integration tool syncs inventory in near real-time, not just once a day, especially for products with lower stock quantities.
Step 5: Manage Orders in One Place
A well-configured integration will pull your eBay orders into Shopify (or into your integration platform) so you can manage fulfilment from a single location. You won't need to log into eBay separately to check for new orders.
From your centralised view, you can:
- Review and process eBay orders alongside your Shopify orders
- Print shipping labels for eBay orders using your preferred carrier
- Mark orders as dispatched, which automatically updates the tracking on eBay and notifies the buyer
- Handle returns or refunds from a single dashboard
Step 6: Connect to Your Accounting Software
Orders from both Shopify and eBay need to flow into your accounting software for invoicing, GST reporting, and reconciliation. If you're on MYOB, Xero, or QuickBooks, setting up this connection is the step that saves the most time over the long run.
An integration platform like Web Ninja handles this automatically. Every order, from both channels, creates the appropriate record in your accounting software, including correct tax treatment and customer details. You don't need to manually enter anything.
Common Issues and How to Solve Them
-
Listings not going live on eBay Usually caused by missing item specifics or incorrect category mapping. Check eBay's listing requirements for your category and ensure all required fields are filled in.
-
Inventory not syncing correctly Check that the SKU codes in Shopify match the identifiers used in your integration tool. Mismatched SKUs are the most common cause of sync failures.
-
eBay orders not appearing in Shopify This can be a permission issue. Re-authorise the eBay connection in your integration tool and check that order syncing is enabled.
-
Price discrepancies between channels Review your pricing rules in the integration tool. If you've set a markup for eBay, confirm it's being applied correctly and that GST is handled consistently.
Frequently Asked Questions
Do I need a separate eBay store to sell alongside Shopify?
An eBay Store subscription is not mandatory to list on eBay, but it's strongly recommended for businesses planning to list more than a few items. A Store subscription reduces your final value fees and gives buyers a dedicated page to browse your listings.
How do eBay fees work for Australian sellers?
eBay Australia charges a final value fee on each sale, typically 10–13.9% depending on the category. Some categories have different rates. There are also optional promoted listing fees if you want more visibility. Make sure your eBay pricing accounts for these fees so you're not selling at a loss.
Can I use the same product images from Shopify on eBay?
Yes. Most integration tools pull your Shopify product images and use them in your eBay listings. eBay has image quality requirements (minimum 500px on the longest side, no watermarks), so make sure your Shopify images meet those standards.
Will my Shopify inventory automatically update when I sell something on eBay?
Yes, if you have inventory sync configured correctly in your integration tool. This is one of the most important features to verify before going live on both channels.
What happens if I run out of stock in the middle of an eBay listing?
A connected integration will automatically end or relist your eBay listing based on stock availability. When your quantity drops to zero in Shopify, the eBay listing will be taken down. When stock is replenished, the listing can be relisted automatically depending on your settings.
