How to Cross-List Between eBay, Facebook & Gumtree
Key Takeaway
List on eBay, Facebook & Gumtree simultaneously — create once, publish to all three with auto-delist when sold. SyncSellr is the only UK tool that supports all three platforms.
eBay, Facebook Marketplace, and Gumtree are the three biggest platforms for selling physical goods in the UK. Together, they account for over 60 million monthly visits. If you're only listing on one of them, you're leaving money on the table.
This guide shows you how to list on all three simultaneously using SyncSellr — the only UK cross-listing tool that supports all three platforms, including Gumtree.
Why These Three Marketplaces?
Each platform attracts a different type of buyer:
- eBay buyers search by product. They know what they want and use filters to find it. They're comfortable with shipping and expect buyer protection.
- Facebook Marketplace buyers browse locally. They're looking for deals near them and prefer collection. The social element (seeing the seller's profile) builds trust.
- Gumtree buyers are high-intent classified shoppers. They're specifically on Gumtree to buy something, and they expect local collection with cash payment.
An item that sits unsold on eBay for weeks might sell within hours on Gumtree to a local buyer. The pair of trainers that gets lost in Facebook's algorithm might get immediate offers on eBay from a nationwide audience.
The Manual Way (Don't Do This)
The old approach to cross-listing looks like this:
- Open eBay. Create listing. Upload photos. Write description. Set price. Choose category and item specifics. Publish.
- Open Facebook. Create listing. Upload the same photos. Retype the same details. Publish.
- Open Gumtree. Create listing. Upload photos again. Retype everything. Choose Gumtree categories. Publish.
- When it sells on Facebook, go to eBay and end the listing. Go to Gumtree and delete it.
For each item, this takes 15-25 minutes of repetitive data entry. For 10 items, that's over 3 hours of work that could be done in 15 minutes with cross-listing software.
The SyncSellr Way
Step 1: Connect Your Accounts
eBay: One-click OAuth. SyncSellr guides you through setting up eBay business policies if you haven't already.
Facebook & Gumtree: Install the SyncSellr Chrome extension and log into both sites in Chrome. The extension syncs your sessions securely (AES-256 encrypted).
Step 2: Create Your Listing Once
In the SyncSellr dashboard, create a single listing:
- Upload photos (drag and drop, reorder, AI background removal available)
- Add title and description (or use AI to generate them)
- Set your price (AI pricing suggestions available)
- Choose a category (SyncSellr maps it to the right category on each marketplace)
Step 3: Select All Three and Publish
On the cross-list screen, tick eBay, Facebook Marketplace, and Gumtree. Hit publish. SyncSellr handles each one differently:
- eBay: Created via the official Inventory API. Reliable, fast, with full inventory sync.
- Facebook: Browser automation fills in the listing form automatically.
- Gumtree: Browser automation fills in Gumtree's forms automatically (SyncSellr exclusive).
Step 4: Sell and Auto-Delist
When your item sells on any platform, mark it as sold in SyncSellr. Enter the sale price, and SyncSellr automatically:
- Removes the listing from eBay (via API)
- Removes the listing from Facebook (via automation)
- Removes the listing from Gumtree (via automation)
- Logs the sale in your profit dashboard
Category Mapping
One of the trickiest parts of manual cross-listing is choosing the right category on each platform. eBay has thousands of specific categories. Facebook has broad categories. Gumtree has its own classification system.
SyncSellr handles this automatically. You choose a category once (from 65+ options covering furniture, fashion, electronics, and more), and SyncSellr maps it to the correct category on eBay, Facebook, and Gumtree. For eBay, it also fills in item specifics like brand, colour, and material.
What About Etsy?
SyncSellr also supports Etsy via the official OAuth API. If your items are suitable for Etsy (vintage, handmade, or unique items), you can tick all four UK marketplaces and publish everywhere at once.
Pricing
The SyncSellr Reseller plan is £29.99/month with a free 4-day trial. That gives you unlimited listings across all 4 marketplaces, AI-powered descriptions and pricing, auto-delist on sale, and a full sales analytics dashboard.
Consider what 3+ hours per week of your time is worth. For most resellers, the tool pays for itself after the first cross-listed sale.
