Facebook Marketplace is excellent for fast, local sales but limited in reach. eBay puts your items in front of 27M+ UK buyers with buyer protection and shipping infrastructure. SyncSellr connects both so you never have to choose.
Start Cross-Listing FreeFacebook Marketplace serves local buyers. eBay serves the entire UK and beyond. Cross-listing means your item sells wherever the demand is, local or nationwide.
Your eBay listings are created via the official Inventory API. Proper categories, item specifics, and business policies are applied automatically by SyncSellr.
SyncSellr can import your existing Facebook Marketplace listings via browser automation. Photos, descriptions, and prices are pulled into your dashboard for cross-listing.
eBay provides buyer protection and structured payments. Cross-listing from Facebook to eBay gives buyers more confidence, which can mean faster sales at higher prices.
Install the SyncSellr Chrome extension and log into Facebook. Authorise eBay via one-click OAuth. No API keys needed for either.
Import your existing Facebook Marketplace inventory, or create new listings in the dashboard with AI-powered descriptions.
Select eBay and hit publish. SyncSellr creates your eBay listing via the official API with proper categorisation and item specifics.
Selling on just one marketplace limits your buyer pool. UK sellers who cross-list between Facebook Marketplace and eBay tap into two distinct audiences. Each platform has different buyer demographics, search behaviours, and pricing expectations. What doesn't sell on one platform often moves quickly on the other.
For Facebook Marketplace, SyncSellr automates Facebook Marketplace using browser automation via the Chrome extension, handling photos, descriptions, categories, and pricing. For eBay, SyncSellr connects via the official eBay Inventory API, giving you reliable, fast publishing with full inventory synchronisation. Together, these two platforms cover a significant portion of the UK's online buying activity, and SyncSellr is the only tool that connects them both from a single dashboard.
The time savings are substantial. Cross-listing manually between two marketplaces means duplicating photos, rewriting descriptions for each platform, managing separate conversations, and remembering to delist when an item sells. SyncSellr handles all of this automatically. You create one listing, publish to both platforms, and when the item sells, it's delisted from the other marketplace with one click. Your sales analytics track performance across both channels so you can see which marketplace works best for each category.
