Causee vs Vinted at a glance

Scale: the part that is not close

It is worth getting this out of the way honestly, because a comparison that pretends a three-month-old marketplace is a peer of Vinted is not a comparison, it is marketing.

Vinted has been running since 2008, operates across more than twenty markets, and reports more than 100 million registered members. It is, for a large share of British sellers, the default place to sell clothes.

Causee launched publicly in autumn 2026. It is UK-only. We were able to count its complete live catalogue because it is small enough to count: 2,011 listings on 3 September 2026, of which 1,261 were fashion, 312 home and garden, and 260 filed under “Other”. Books, jewellery, health and beauty, art, mother and baby, electronics and furniture together made up under 180 listings.

Causee publishes no buyer count, no traffic figure, no sales data and no funding announcement. It has no mobile apps yet. As of the date of writing we could not find a Trustpilot profile, a Reddit thread or a single independent user review of it anywhere. The press coverage that exists — four pieces, all from August 2026 — is clearly derived from one press release.

None of that means it will not work. It does mean that any claim about how well things sell there, including from us, would be invention. What can be said is factual: the catalogue is small, the categories are concentrated in fashion, and prices are low — across a random sample of sixty listings, everything fell between £1 and £65.

Two different ways of making money

Both platforms have arrived at the same seller-facing answer — charge them nothing — from different directions, and the difference shows up on the buyer’s receipt.

Vinted charges buyers a Buyer Protection fee on every order. Its UK help centre states this is “usually 3% to 8% + £0.3 to £0.8”, that it is mandatory for every order made through Vinted, that it is added automatically at checkout, and that it varies with item characteristics, order value and order type. Vinted also sells sellers optional visibility features, which is the other half of the model.

Causee also charges buyers a protection fee, and describes it only as “a small Protection Fee”. It does not publish the amount. We looked for it on the dedicated Protection Fee page, in the FAQ, in the terms of service, on the blog, and in the marketplace’s own public configuration assets — which expose the seller-side commission as literally zero and deliberately do not expose a buyer-side one, meaning the calculation happens privately on Causee’s servers. If you want to know what your buyer will be charged, put something in a basket and look; there is no published figure to cite.

Causee has no equivalent of Vinted’s paid visibility features at all. There are no promoted listings, no bumps, no boosts and no ranking algorithm. That is a real difference in kind: on Causee nobody can outspend you, and equally nothing you do lifts you.

The charity claim, read carefully

Causee’s distinguishing feature is that it donates its profits to charity, and the detail matters because it is easy to get wrong in both directions.

The seller donates nothing. Causee’s FAQ answers the question in as many words: “Do sellers donate their profits to charity? No. Sellers keep 100% of the price they sell their items for. Causee does not ask sellers to donate their profits. Instead, Causee donates its own profits…” There is no opt-in donation at checkout and no percentage slider.

Causee is not itself a charity. Its own FAQ states: “Causee is not a registered charity. We operate using a social enterprise model.”

“100% of profits” is hedged, by Causee. Its own wording is: “After covering our operating costs, investing in the ongoing development of the platform, maintaining prudent working capital and appropriate financial reserves, 100% of Causee’s own profits are donated to charities.” That is four deductions ahead of the hundred per cent. Every trading company has costs, so this is not a criticism — but “100% of profits” and “100% of revenue” are very different claims and only the first is being made.

You cannot currently pick the charity. Causee’s marketing refers to charities chosen by its community, and its marketplace configuration really does contain a listing field labelled “Pick a charity to support” with ten well-known options behind it. It is scoped to a listing type that does not exist on the live marketplace, so it never renders. Causee’s FAQ describes the capability in the future tense. Its named founding partner is Pepala, a UK organisation that redirects surplus British educational supplies to schools in Malawi.

Vinted makes no comparable claim, and it would be unfair to fault it for that — it is a commercial marketplace and does not present itself otherwise. If the charitable angle is what draws you to Causee, the accurate version to give a buyer is that the platform donates its own profits, not that your sale funds a cause you selected.

What each one costs, seller and buyer

For a seller the two are, on fees, genuinely identical: you keep the price you sold at, on both. That is unusual enough to be worth stating twice, because most marketplace comparisons come down to a fee table and this one does not.

Where it matters is the buyer’s side, and only indirectly. A buyer-paid fee sits on top of your asking price at checkout, so it affects what your item feels like it costs. Vinted’s is published and predictable enough to price around. Causee’s is not published at all, which makes it impossible to model — and worth checking yourself before you assume the two behave the same way at the till.

Listing on each: what you can actually say about an item

This is where the two diverge most sharply, and the direction is counter-intuitive: Causee is quicker to list on precisely because it captures less.

Causee’s schema is narrow. A listing carries a title of up to 60 characters, an uncapped plain-text description, at least one photo (JPG, GIF or PNG up to 20 MB each; live listings commonly carry up to fifteen), a price, one of ten categories, one of six apparel sub-categories, a size, a condition, optionally a single colour from sixteen, and two postage prices you type yourself.

Three absences define it:

• No brand field. None at all. Sellers type the brand into the title or write “Brand: Primark” into the description. Buyers cannot filter by brand because there is nothing to filter on.
• No letter sizes and no menswear sizing. Causee’s roughly 78 size options cover UK women’s clothing 4–24, shoes 3–13, and infant, kids and baby scales. A medium jumper has no honest value to select.
• No bottom condition rung. Its five conditions are New, New with tags, Used – Excellent, Used – Good and Handmade. There is no Fair, Satisfactory or Poor, so a well-worn item gets rounded up.

Vinted’s schema is richer in exactly those three places. Titles run to 100 characters. Brand is a structured entity with its own identifier, which powers the brand filter and the follow-a-brand feed — a listing without one is invisible to a major discovery path. Sizes cover the full range including letter sizes and menswear. And its five conditions — New with tags, New without tags, Very good, Good and Satisfactory — include the honest bottom rung Causee lacks.

The practical upshot is a genuine trade. Listing on Causee is faster because there is less to fill in. Being found on Causee depends almost entirely on your title, because keyword search across the title and description is most of what the platform offers — its filters are limited to keyword, price band, category, sub-category, condition and colour. On Vinted you fill in more and get more discovery surface in return, but you are also one listing among tens of millions.

What that means for how you write

On Causee, put the brand in the title. It is not duplication, it is the only mechanism available, and with 60 characters you have room for roughly brand, item, colour and size and nothing else. Put the size in the title too if it is a letter size, because the size field cannot hold it.

On Vinted, fill in the structured fields properly and let the title do a different job. The brand entity, the size and the category are doing the finding; the title is doing the persuading.

What is actually selling on each

On Causee we can be exact, because the catalogue is countable. As of 3 September 2026: fashion 1,261 listings, home and garden 312, “Other” 260, books 50, jewellery 41, health and beauty 35, art 17, mother and baby 16, electronics 13 and furniture 6. Fashion is not merely the biggest category, it is nearly two thirds of the entire platform — and every one of the six sub-categories available is an apparel one, which tells you where the product design attention has gone.

That “Other” bucket is worth a warning: at 13% of the catalogue it is the third largest category on the site, which means a meaningful share of Causee stock is filed somewhere buyers cannot usefully browse. If a real category fits your item, use it.

Prices are low. In a random sample of sixty listings, every single one fell between £1.00 and £65.00. Causee today is a low-ticket marketplace, and pricing a £300 designer piece there is fighting the current rather than testing the market.

Vinted’s mix is not something anyone can count from outside, but its centre of gravity is well established: everyday second-hand fashion, with strong menswear, kids’ and homeware seams alongside it, and a functioning market at both the low-ticket and the mid-market end. The categories where Causee is currently thinnest — menswear, anything brand-led, anything above about £65 — are precisely the ones Vinted handles routinely.

Postage and payouts

Vinted handles postage; Causee does not.

On Vinted the buyer chooses and pays for a delivery option at checkout, and the label is produced for you. On Causee there are no integrated shipping labels and no courier partner at all. Every listing requires two postage prices — one for a single item, one for each additional item bought together — which you set yourself. When something sells you buy postage at retail, send it however you like, and mark the order shipped. Local pickup is supported as an alternative, and nine of the sixty listings we sampled offered it, which suggests bulkier home and garden stock moves that way.

Two consequences. There is no marketplace-negotiated rate subsidising a mistake, so price the service you will actually use rather than guessing. And there is no tracking integration, so in a non-delivery claim your own proof of postage is the only evidence you will have. Keep it.

On payouts, Causee is slow. Funds sit in escrow through Stripe Connect and are released seven days after delivery is confirmed, after which Causee says payments “typically arrive within 3–7 business days”. Realistically that is a fortnight from the buyer paying to money reaching your bank. It is the mechanism that makes the buyer protection meaningful, so it is a trade rather than a flaw — but if you recycle proceeds into stock, plan for it.

One setup step that catches people: Causee runs payouts through Stripe Connect, and until you have completed Stripe’s onboarding your listings cannot accept an order at all. Buyers see a message saying the listing is unavailable because the author has not added payout details. Do it before you list, not after.

Trust, protection and what happens when it goes wrong

Both platforms sell buyer protection funded by a buyer-side fee, and both are explicit that it is not insurance.

Causee’s Purchase Protection Programme covers non-delivery, damage in transit and items not as described. It excludes a buyer changing their mind, and the buyer must report a problem within five days of delivery — a tight window by marketplace standards, and worth knowing when you decide how carefully to pack something.

Causee publishes no standalone returns policy. Its terms note that consumer-to-consumer sales fall outside the statutory cancellation rights that apply to trader sales, and who pays return postage in a successful claim is not documented anywhere we could find. In practice: describe flaws in writing, photograph them, and keep your messages on the platform.

Causee’s prohibited-items policy runs to nine categories — illegal items, weapons and dangerous goods, regulated products including prescription medicines and vaping, animals and wildlife products, adult content, financial products including cryptocurrency, unlawful digital services, unsafe or recalled products, and extremist material. Vinted maintains its own catalogue rules, which differ in places, so a small share of any catalogue will not cross cleanly in either direction.

The asymmetry that matters most is not the policies but the evidence base. Vinted’s dispute process has been exercised millions of times and there is a large body of seller experience about how it behaves. Causee’s has not been exercised publicly at all — there are no reviews, no forum threads and no reported cases. That is not a criticism of the policy; it is a statement about how much you can know before you rely on it.

If you are trading rather than clearing a wardrobe

This is where the gap widens most and it is easy to miss, because neither platform charges you.

Vinted distinguishes between private members and Pro sellers. Pro registration is available to sole traders, charities and registered companies, and it brings a Pro badge on your profile and item pages along with the obligations that come with trading status.

Causee makes no such distinction at all. Its terms treat every transaction as consumer-to-consumer throughout. There is no business-seller registration flow, no VAT-registered tier and no trader-identity disclosure. The only trace of business selling anywhere in the platform is an optional per-listing VAT field offering 20%, 5% or 0%, which is hidden from buyers’ filters and appeared on just four of the sixty listings we sampled.

If you trade at volume, that absence is a real consideration. It is not that Causee forbids it — it does not — but you would be operating on a marketplace that has not yet built the account type, the disclosures or the reporting a trading seller needs. Causee does at least ship a native bulk-upload tool, which is unusual for a platform this young and confirms it expects sellers with real inventory.

Whichever you use, your UK tax position is unchanged by the platform. Selling your own used possessions is generally not trading income; buying to resell is, and the usual thresholds and self-assessment rules apply. Digital platforms operating in the UK report seller data to HMRC regardless of size, so treat income on a new marketplace as just as visible as income on an established one.

Who each one is actually for

Choose Vinted if you want to sell something. That is the blunt version and it is right far more often than not. The buyers are there, the discovery machinery works, postage is handled, and you know what the dispute process does because millions of people have been through it.

Add Causee if any of these describe you:

• You have children’s school uniform. It is a named part of Causee’s stated launch focus and almost no marketplace courts it deliberately. On a 2,000-listing platform that is close to an open goal.
• You are a crafter or small maker. Causee treats “Handmade” as a first-class condition value and names small businesses and crafters in its focus, which is an odd schema decision that happens to be useful.
• You want the charitable angle in your listing. It is a true thing you can say that a competing seller on Vinted cannot — provided you say the accurate version.
• Your stock is numerically sized women’s, kids’ or baby clothing. That is exactly what Causee’s schema was built for, and it will list cleanly.

Causee is a poor fit if your stock is menswear or letter-sized (the size field cannot hold it), if brand is the main reason anyone would buy your item (there is no brand field), if you need fast payouts, or if you are trading at a scale that needs a business account.

The case for using both

Framing this as a choice is mostly a mistake, because the honest arithmetic is that the second listing is close to free. Both platforms charge sellers nothing. Causee explicitly permits it — its FAQ says “Can I still sell on other marketplaces? Absolutely… Causee does not require exclusivity”, and separately confirms that copying listings from another marketplace is fine.

The only real cost is the duplication itself, and that is what a crosslisting tool removes. With FLUF Connect, a listing written once goes to both, and — the part that actually matters — a sale on Vinted closes the Causee listing automatically, so you are not selling the same jumper twice. FLUF supports order sync on Vinted, which is what makes that direction work. The reverse is not yet live: a Causee-origin sale is not currently detected, so you would take the Vinted copy down yourself. Given the relative size of the two catalogues, the direction that fires is the one that is automated.

Two other differences worth knowing if you run both through one tool. Vinted supports automatic relisting, offer management and smart pricing, all of which meaningfully move sales there. Causee supports none of them — crosslisting and mark-as-sold only — and has no boost or promoted-listing product for them to interact with anyway. And Causee runs on a documented public API, so FLUF lists to it entirely server-side.

The realistic expectation to set is this: Vinted will carry your sales, Causee will occasionally surprise you in a category where nobody else is listing, and the second listing will have cost you nothing to find out.
