Crosslist from Causee to eBay — Automatically
Move your Causee listings onto the biggest marketplace in Britain. Neither side charges a UK private seller a selling fee — this page covers exactly what transfers, what Causee never captured, and what to fix on the way.
- You are moving from about two thousand listings to the largest marketplace in Britain. Causee’s own search returned 2,011 live listings when we counted on 3 September 2026. That is the entire catalogue. eBay is where the buyers already are, and this route costs a UK private seller nothing on either side.
- Both sides charge UK private sellers no selling fee. Causee takes 0% commission and no listing fee. eBay removed selling fees for UK-based private sellers on 1 October 2024. On this route you are not paying for reach — you are paying for the tool that duplicates the listing.
- The title has to grow, not shrink. Causee caps titles at 60 characters; eBay allows 80. Crosslisting the other way truncates — this direction gives you 20 characters back, and on eBay you should use them.
- Causee has no brand field, and eBay wants one. Brand is a genuine item specific on eBay and a real search filter. Coming from Causee there is nothing structured to map, so brand has to be recovered from your title or set on the eBay side.
- Postage flips from manual to integrated. On Causee you type a postage price and post the parcel yourself. eBay gives you discounted Royal Mail and Evri labels bought inside the platform.
- Sold on eBay removes it from Causee automatically. The reverse does not: a Causee sale is not currently detected, so you take the eBay copy down yourself. Said plainly rather than promised as a closed loop.
- Cost: 7 days for £1, then from £9/month — unlimited crosslisting on every plan. There is no free plan.

A charity marketplace and the biggest shop window in Britain
Causee is a UK resale marketplace that charges its sellers nothing and donates its own corporate profits to charity. It launched in autumn 2026, it is deliberately UK-only, and it is small in a way that is easy to under-appreciate: we counted its complete live catalogue at 2,011 listings on 3 September 2026, of which 1,261 — 63% — were fashion. There is no promoted-listings product, no paid boost and no ranking algorithm to fight, which is genuinely pleasant. There is also, so far, no published buyer count, no traffic figure and no independent review anywhere.
eBay is the other end of that spectrum entirely. It is the general-purpose UK marketplace, it has been for twenty-five years, and it carries the search demand for practically every category Causee lists in. Nothing about crosslisting there is novel. The reason to do it is arithmetic: a listing that costs you nothing to duplicate should not sit only in front of a two-thousand-item catalogue.
What makes this particular pair unusual is that neither platform takes a cut from a UK private seller. Causee’s marketplace configuration sets the seller commission to zero per cent, and its FAQ says sellers “keep 100% of the price they sell their item for”. eBay removed selling fees for UK-based private sellers on 1 October 2024 — no final value fee, no per-order charge, no insertion fee. Both platforms moved the cost onto the buyer instead. So this is not a route where you trade margin for reach; you keep the margin and gain the reach.
Causee, for its part, has no objection. Its FAQ answers the question directly: “Can I still sell on other marketplaces? Absolutely. You are free to continue selling on other marketplaces. Causee does not require exclusivity.”
What a Causee listing carries, and what eBay asks for
Causee’s schema is narrow, which makes this direction unusually clean — almost everything Causee holds has an eBay destination, and the gaps are things eBay wants that Causee never captured.
| Causee field | eBay field | Transfer | Notes |
|---|---|---|---|
| Title (60 characters) | Title (80 characters) | ✅ Automatic | Nothing truncates in this direction. You gain 20 characters — use them |
| Description (plain text) | Description | ✅ Automatic | Causee renders plain text; eBay accepts richer formatting you can add later |
| Photos (JPG, GIF, PNG, up to 20 MB each) | Pictures | ✅ Automatic | Causee listings commonly carry up to 15; eBay comfortably accepts that many |
| Price (GBP) | Price | ✅ Automatic | Both are GBP for a UK seller, so no conversion is involved |
| Category (one of ten) | Category (thousands) | ⚡ Smart mapped | Causee’s ten top-level buckets map onto eBay’s far deeper tree; expect to confirm the leaf |
| Sub-category (six, fashion only) | Category refinement | ⚡ Mapped | Only clothing, shoes, baby/toddler, infant’s shoes, kids’ shoes and maternity exist on Causee |
| Condition (five values) | Condition | ⚡ Mapped | See below — Causee has no “fair” or “poor” rung at all |
| Size (UK numeric, kids, baby) | Size item specific | ⚡ Mapped where present | Causee has no S/M/L and no men’s sizing, so many listings carry no size to map |
| Colour (one of 16, single value) | Colour item specific | ✅ Automatic | eBay accepts a single colour happily |
| — | Brand | ❌ No source field | Causee has no brand field. See the next section |
| Postage price you typed | Postage policy / eBay label | ⚠️ Reconsider | eBay’s discounted labels usually beat what you priced by hand on Causee |
| VAT (optional, 20/5/0) | — | ⚠️ Set on eBay | Present on very few Causee listings; handled through eBay’s own business settings |
The brand problem
Causee’s listing schema contains no brand field. Not optional, not hidden — absent. Sellers who want to communicate a brand type it into the title, or write “Brand: Primark” into the description body by hand. Causee’s keyword search reads both, so on Causee that is a perfectly rational thing to do.
On eBay it is not enough. Brand is a real item specific, it drives a search filter that buyers use constantly, and eBay’s own guidance treats missing item specifics as a ranking problem rather than a cosmetic one. Coming from Causee there is no structured brand value to carry across, so it has to be recovered.
In practice that means one of two things. If you keep your master catalogue in FLUF Connect rather than in Causee — which is the normal arrangement when you sell on several channels — the brand lives there as a product attribute and reaches eBay properly, with Causee simply being the channel that has nowhere to put it. If Causee genuinely is your source of truth, expect to add brand on the eBay side for anything where it matters, which is most fashion.
The same logic applies in reverse and is worth naming: this is the single field that makes Causee a poor source of truth for a multi-channel seller. It is an excellent extra channel and a lossy master catalogue.
Condition, translated
Causee offers exactly five conditions: New, New with tags, Used – Excellent, Used – Good and Handmade. eBay’s clothing conditions run further down the scale, and that asymmetry causes a specific, avoidable problem.
| Causee | Sensible eBay equivalent |
|---|---|
| New with tags | New with tags |
| New | New without tags |
| Used – Excellent | Pre-owned, described as excellent |
| Used – Good | Pre-owned — and check the item, because this is Causee’s floor |
| Handmade | Handmade, or the relevant new condition |
The thing to watch is that Causee has no bottom rung. There is no “Fair”, no “Satisfactory” and no “Poor”, so a genuinely well-worn garment gets rounded up to “Used – Good” when it is listed there. If you crosslist that value to eBay unexamined, you carry an overstated condition into a marketplace with a far more active returns and not-as-described process than a 2,000-listing startup. Read the description, not the dropdown, on anything you graded at Causee’s floor.
eBay also requires used clothing to be properly cleaned, and bans used underwear and socks outright, with bras permitted. Causee’s own prohibited-items policy is broader in some places and narrower in others, so a small share of a Causee catalogue will not cross.
Who pays what, on each side
| Causee | eBay UK | |
|---|---|---|
| Listing fee | None, unlimited | None for private sellers; 300 free listings a month |
| Seller commission | 0% | None for UK-based private sellers since 1 Oct 2024 |
| Business-seller commission | No business tier exists | 11.9% in clothing, shoes and accessories, plus a per-order charge and a 0.35% regulatory operating fee |
| Buyer-side fee | Protection Fee — amount not published | Buyer Protection fee on private-seller listings: £0.10 flat, plus 7% up to £20, 4% from £20–£300, 2% above |
| Payouts | Stripe Connect; released 7 days after delivery, then 3–7 business days | eBay managed payments, typically within a couple of days of order confirmation |
| Dispute window | 5 days from delivery | eBay Money Back Guarantee, considerably longer |
Two things are worth pulling out. First, Causee does not publish its Protection Fee anywhere — not on the dedicated page, the FAQ, the terms or its public configuration, which deliberately exposes only the seller-side commission. We looked. If you want to know what your buyer pays, add something to a basket and see. Second, eBay’s “free” private selling is not free to the market: the cost moved to the buyer as the Buyer Protection fee, which is shown inside the displayed price. A £20 item from a private seller shows to the buyer at around £21.50; the same item from a business seller shows at £20 and the seller absorbs roughly 12%. That is worth understanding before you conclude eBay is strictly cheaper.
The payout difference is the one you will feel day to day. Causee holds funds in escrow and releases them seven days after delivery is confirmed, after which it says money “typically arrives within 3–7 business days” — realistically a fortnight end to end. eBay is materially faster. If cash flow matters, that alone is an argument for having the eBay listing live.
Postage: typed by hand, then bought in-platform
This is the biggest operational change between the two, and it is entirely in eBay’s favour.
Causee has no integrated shipping labels and no courier partner. Every listing carries two required postage fields — a price for one item and a price for each additional item — which you set yourself. When something sells you buy postage at retail, send it however you like, and mark it shipped. Local pickup is supported as an alternative. There is no tracking integration at all, so in a non-delivery claim your own proof of postage is the only evidence you will have.
eBay sells you the label inside the platform at negotiated rates, prints or generates a QR code, and feeds the tracking back automatically. For a seller shifting real volume that is both cheaper and far less work.
The practical consequence for crosslisting: do not simply carry your Causee postage price across. You set that number against retail postage. On eBay the same parcel usually costs you less, and a postage price that is visibly above the market is one of the more reliable ways to lose an eBay sale. Set an eBay postage policy properly rather than inheriting a hand-typed figure.
How to crosslist with FLUF Connect
- Connect Causee. It runs on a documented public API, so FLUF lists to it server-side with your Causee credentials — no browser extension and nothing left running.
- Connect eBay through eBay’s standard OAuth authorisation.
- Import your Causee listings. FLUF reads title, description, photos, price, category, sub-category, size, condition and colour.
- Fill the gaps that matter. Brand, above all, and the eBay category leaf. This is a one-off per product, not per listing.
- Set an eBay postage policy rather than reusing the Causee figure.
- Select and crosslist. One item or the whole catalogue.
Both channels are ordinary server-side integrations, so this runs in bulk and unattended. Auto-crosslisting rules can push new Causee stock to eBay as it appears.
What syncs — and what does not
- Sold on eBay → withdrawn from Causee, automatically. eBay supports order sync, so the sale is detected and the Causee listing is closed. This is the direction that prevents overselling and it is the main reason to run the pair through an integration.
- Sold on Causee → you remove it from eBay yourself. Order sync from Causee is not available, so a Causee-origin sale is not currently detected. With a catalogue of two thousand listings the odds are that most of your sales will come from the eBay side anyway — but know which half of the loop is manual.
- Price and description edits made in FLUF push to both.
- Automatic relisting, offer management and smart pricing work on eBay. None of them are available on Causee, which supports crosslisting and mark-as-sold only. Causee has no promoted-listings or boost product for them to interact with in any case.
Why keep the Causee listing at all?
A fair question, given the asymmetry. Three honest reasons.
It costs you nothing. Zero commission, zero listing fee, no subscription, and the duplication is automated. There is no scenario where the Causee copy loses you money on an item that sells on eBay, because the sale takes it down.
The competition is thin. Two thousand listings, no paid boosts and no ranking algorithm means a well-titled listing in a real category is near the front of a very short queue. Causee’s stated launch focus includes children’s school uniform — a category almost nobody courts deliberately — and if you have uniform stock this is an unusually uncontested place for it.
The proposition is something you can say. Causee is not a charity itself; it is a social enterprise that donates its own profits, with Pepala as its founding partner. But it is a genuinely different pitch in a category where everything else competes on price and convenience, and it gives a listing a sentence that is true and that no competing seller on eBay can make.
What it is not is a reason to leave eBay. Treat Causee as somewhere your stock also is, at no marginal effort, rather than somewhere you move to.
What FLUF Connect costs
FLUF Connect starts at 7 days for £1, then from £9/month. There is no free plan. Every plan includes unlimited crosslisting across all supported channels; the tiers differ in how often sales are checked and how much history you keep, not in how many items you may list.
For this pair, Starter covers the essentials: the crosslisting itself and the eBay-sold-to-Causee-withdrawn protection. The Seller plan at £29/month adds automated relisting, offer management and smart pricing, all of which apply on the eBay side and none of which Causee supports — so upgrade when eBay is carrying your volume, not before. Automation is included in every plan rather than sold as an add-on.

Frequently Asked Questions
For a UK private seller, no selling fees on either side. Causee charges 0% commission and no listing fee — its marketplace configuration sets the seller commission to zero. eBay removed selling fees for UK-based private sellers on 1 October 2024, and gives 300 free listings a month. Both platforms moved the cost to the buyer instead, so you keep the margin and gain the reach.
Yes, with room to spare. Causee caps titles at 60 characters and eBay allows 80, so nothing truncates in this direction — you gain 20 characters. Use them: because Causee has no brand field, Causee titles are usually written tightly, and an eBay title has room for the brand, the size and a keyword the Causee version could not fit.
Causee has no brand field at all, so there is no structured value to carry across. Brand is a real item specific on eBay and a search filter buyers use constantly, so it has to be recovered — either from your master catalogue in FLUF Connect, where brand lives as a product attribute, or added on the eBay side. This is the main reason Causee makes a poor master catalogue even though it is a good extra channel.
New with tags maps straight across; Causee's “New” is closest to eBay's New without tags; Used – Excellent and Used – Good both become Pre-owned. The thing to watch is that Causee has no “Fair” or “Poor” rung, so genuinely well-worn items get rounded up to Used – Good when listed there. Read the description rather than the dropdown before carrying that value onto eBay.
No. Causee has no integrated labels or courier partner, so you set a postage price by hand against retail rates and post the parcel yourself. eBay sells you a discounted label inside the platform and feeds tracking back automatically, which is usually cheaper. A postage price visibly above the market is one of the more reliable ways to lose an eBay sale, so set an eBay postage policy properly instead of inheriting the figure.
Yes. eBay supports order sync, so a sale there is detected and the Causee listing is closed for you. The reverse is not live: a sale that happens on Causee is not currently detected, so you remove the eBay copy yourself. Given Causee's catalogue was 2,011 listings when we counted it in September 2026, most sales on this pair will come from the eBay side.
Yes, explicitly. Causee's FAQ says: “Can I still sell on other marketplaces? Absolutely. You are free to continue selling on other marketplaces. Causee does not require exclusivity,” and separately confirms that copying listings from another marketplace is fine.
eBay publishes its structure for private-seller listings: a flat £0.10 per item plus 7% of the item price up to £20, 4% from £20 to £300 and 2% above that, paid by the buyer. Causee does not publish its Protection Fee amount anywhere — not on the dedicated page, the FAQ, the terms or its public configuration, which exposes only the seller-side commission. To see it, add an item to a basket on Causee.
It costs nothing to keep, and a sale on eBay takes it down automatically, so there is no overselling risk. Causee's small catalogue and complete absence of promoted listings or paid boosts means a well-titled listing sits near the front of a short queue, and its stated launch focus includes children's school uniform — a category very few marketplaces court deliberately. Treat it as somewhere your stock also is, not somewhere you move to.
