FillSell for eBay: the eBay crosslisting tool you run from your phone

One photo. One stock. An eBay listing that goes out while your laptop stays shut. That's what a linked eBay account changes, and it's where FillSell starts on eBay: you give the orders from your phone, eBay's official API does the posting, and once the item sells, its proven copies come down from your other marketplaces.

Why put your items on eBay as well?

Because eBay is another shop window, with another crowd. eBay reports 136 million active buyers worldwide at 30 June 2026, across more than 190 markets, and in those second-quarter 2026 results the group puts four areas forward worldwide: collectibles (trading cards included), car and motorbike parts, luxury (watches) and pre-loved fashion. An item gathering dust on one marketplace can find its buyer on another, with the same photos.

And since 1 September 2026, the maths on ebay.fr has changed: a private seller whose address is in the European Economic Area no longer pays transaction fees, in any category. Mind the catch: eBay requires a business account from anyone who sells items bought to resell. So a reseller who buys stock is often, in eBay's eyes, a business seller, with business fees. The details are in the table below.

The real brake was never posting one listing. It's the repetition: typing every item into one more form, hunting for the right eBay category, keeping an eye on one more shop, and making sure the same item never sells twice. That's exactly the work FillSell takes off your hands.

eBay France rules to know before you list

This table sums up eBay France's help pages, read on 9 October 2026. eBay updates its rules: check them before you set your prices.

Sources, read on 9 October 2026 (pages in French): private seller fees, business seller fees, Buyer Protection, business seller policy, duplicate listings. The fee-free rule depends on the address on your eBay account being in the EEA: an account based in the UK or Switzerland, for instance, isn't covered. FillSell doesn't decide your seller status and gives no tax advice: if in doubt, eBay's own page is the reference.

What FillSell changes on eBay

One photo, and your eBay listing is written

Take a photo of the item: Lens recognises it, reads the brand when it's printed on the item, suggests a condition and a price based on comparable listings found online, then writes the title and description. From the app, the same scan writes the eBay version of your listing: eBay category, size, colour. If no category fits, the app asks you to pick one; it never greys eBay out. You read every version before anything goes out.

The app speaks English; your ebay.fr listing speaks French. Lens drafts the eBay version in French, for eBay France's buyers, even when you use FillSell in English.

eBay's own app can also build a listing from photos. The difference with Lens (in French): your listing is written once for all your marketplaces, and the item lands in a single stock that keeps track of its copies wherever it's live.

Linked account: your listing goes out, computer off

On your other marketplaces, the Chrome extension does the legwork, in your own session, from your computer while it's on. On eBay France, once your account is linked, your listings go out through eBay's official API, from our servers. Laptop shut, Chrome closed: they go out anyway. Tick eBay from your phone, on the bus or at a flea market, and your listing is on its way. In the app, the eBay box says it plainly: it leaves from our servers, without the extension.

Your eBay stock, filed with everything else

One tap on Sync and the eBay listings you already have live land in your stock: through the official API if your account is linked, through the extension otherwise. The same item live on eBay and on Vinted becomes a single card: FillSell compares the photos and the title, never one without the other, and asks you whenever it's unsure. Syncing (in French) only reads your listings: nothing is published or edited. It's free, with no limit.

A whole batch, eBay included

Publish a whole batch of items in one go: you pick the marketplaces, FillSell prepares, you check, off it goes. Each item only goes where it isn't live yet. For eBay, there's no weight or parcel size to enter: postage comes from the shipping policy you set once on eBay.

Linking your eBay account: the right move for your account

You link your account once. You give your consent on eBay's official page; FillSell receives an authorisation, never your password. That API is the access eBay itself opens to apps, through its developers program, whose licence agreement forbids apps from collecting their users' eBay IDs or passwords.

Without a link, the extension can fill in the eBay form in your own session, with your computer on. But eBay often asks you to sign in again for security: the listing then waits, and the app asks you to connect your eBay account. On eBay, the safest route is to link your account. The details, marketplace by marketplace, are on the account safety page (in French).

FillSell isn't affiliated with eBay in any way, nor endorsed or sponsored by it: it goes through the access eBay provides for apps.

Sold on eBay: what happens next?

This is where FillSell earns its keep. One sale, and everything else follows:

1. FillSell spots the sale. It checks your eBay listings and, with a linked account, receives your account's orders.
2. The sale records itself. Nothing to confirm. When FillSell records an eBay sale, you get an email.
3. Sold here, removed there. The item's copies FillSell has proof of (posted through FillSell, attached to the item's card, or linked by you) are removed from your other marketplaces. Those removals go through the extension: computer on, Chrome open. Computer off? They wait and go out the next time Chrome opens.
4. Any doubt, FillSell asks. A copy without proof is never removed behind your back: you get the question “Already sold?”, with “Yes, remove it” or “No, it's another copy”. A “No” is never asked again.
5. Your margin stays up to date. Purchase price, sale price, the fees you note down: margin and profit work themselves out, sale by sale.

And the other way round? If the item sells on Vinted first, that sale is recorded on its own too. On Leboncoin and Beebs, you confirm it with one tap. Your proven eBay listing then comes down, through the official API when it was posted through FillSell. A matching title is never enough: two listings that only share a title trigger the question, not a removal.

Choosing an eBay crosslisting tool from Europe: four questions

Several well-known eBay crosslisting tools are built for American marketplaces. Crosslist works with eBay .com, .co.uk, .ca and .com.au and says it does “not support users residing in the European Union”; List Perfectly says it “supports U.S. marketplaces only”; Vendoo's help centre lists ebay.com next to US marketplaces such as Poshmark and Mercari. That's who they're built for. If you sell from France, ask any tool these four questions. Here are FillSell's answers:

1. Which eBay site does it list on? eBay France (ebay.fr) today, through eBay's official API once your account is linked.
2. Does posting need your computer on? Not on eBay with a linked account. On your other marketplaces, the extension works in your own Chrome session, computer on, while your phone gives the orders.
3. What happens after a sale? eBay and Vinted sales are recorded on their own; sales elsewhere take one tap; proven copies come down; anything uncertain becomes “Already sold?”.
4. Which marketplaces share the stock? Vinted, Leboncoin, eBay, Beebs, and Depop, one card per item.

Frequently asked questions

Is FillSell an official eBay tool?

No. FillSell isn't affiliated with eBay, nor endorsed or sponsored by it. When you link your account, it goes through eBay's official API, the access eBay opens to apps: you give your consent on eBay's page, and FillSell never sees your password.

Do I need to keep my computer on to sell on eBay?

Not to post, if your eBay account is linked: your listing goes out through eBay's official API even with your computer off, and your eBay sale is recorded without it. Without a link, the Chrome extension does the posting: computer on, Chrome open. To remove a sold item's copies from your other marketplaces, the extension needs your computer on; if it's off, those removals wait for the next time Chrome opens.

Can I use FillSell with eBay.com, eBay UK or eBay Germany?

Not today: FillSell lists on eBay France (ebay.fr). An eBay account registered in another country isn't published, and the app tells you why.

Will my eBay listings be in English or French?

In French. Your listings go to ebay.fr, so Lens drafts the eBay version in French for eBay France's buyers, even when you use the FillSell app in English. You read and edit everything before it goes out.

Is selling on eBay France really free since September 2026?

For a private seller whose address is in the European Economic Area, there have been no transaction fees on ebay.fr since 1 September 2026, in any category. Still paid: listings beyond 150 a month (€0.35 each), optional upgrades, and shipping outside the euro area and Sweden. The buyer pays a Buyer Protection fee, included in the price shown. And if you buy to resell, eBay asks you for a business account, with its own fees.

What happens to my eBay listing if the item sells on Vinted?

The Vinted sale is recorded on its own, then your eBay listing is removed if FillSell can prove it's the same item, through the official API when it was posted through FillSell. Any doubt, for example two listings that only share a title, and FillSell asks you “Already sold?” before touching anything.

Why is my eBay listing still waiting?

Two possible reasons. Your eBay account doesn't have its selling policies yet (payment, returns, postage) or isn't ready to sell: set that up on eBay, and the listing waits until it's done. Or your account isn't linked and eBay asked you to sign in again for security: the app then asks you to connect your eBay account. Link it: that's the recommended route.

eBay owns Depop now: does my linked eBay account cover Depop?

No. eBay completed its acquisition of Depop on 30 July 2026, but Depop is still its own marketplace, with its own accounts. For FillSell, they're two marketplaces: Depop goes through the Chrome extension, in your Depop session, computer on, once you've allowed Depop access with one click in the extension. Both end up in the same stock.
