How to sell on Catawiki: a step-by-step guide and fees (2026)

By Raquel · Updated 19 October 2026 · 5 min read

If you own collectibles, Catawiki is one of Europe’s biggest shop windows for selling them. We sell gold nuggets there every week; this is what we wish we had known on day one.

What you can sell on Catawiki

Catawiki auctions special objects: art, antiques, jewellery, watches, coins and stamps, minerals and fossils, wine, classic cars, comics, vintage toys and more. Its experts accept or decline each object based on rarity, age, condition, origin and quality. It is not the place to sell second-hand clothes or everyday electronics: what works here are pieces with something special about them.

According to the platform, it brings together more than 10 million buyers, operates in 60 countries and 17 languages, and has more than 240 experts across over 22 categories.

Step 1: create your seller account

Registration is free. As a seller you will need to verify your identity once through a payment provider such as Stripe or Payoneer; that is what lets your buyers see you are a verified seller. You can sell as a private individual or as a business.

Step 2: submit your object (it’s free)

A guided process helps you upload photos and fill in the object’s details. Submitting costs nothing: you only pay if it sells.

For high-value objects you can agree a reserve price with the expert, the minimum below which it won’t sell, or add a buy-now price for buyers who don’t want to wait for the end of the auction. Depending on what you choose, bidding starts at €1, at 50% of the reserve or at the reserve itself.

Step 3: the expert review

An expert in the category reviews your submission remotely, from your photos and description. They check that the listing has the information buyers need, may ask you for more details or photos and, if they accept it, place the object in a suitable weekly auction. If it isn’t a fit, they will tell you.

A lot depends on this review, so it pays to get the photos and description right from the start.

Step 4: the auction

While the auction runs, you can watch the bids come in. Because last-minute bids push the closing time back, the final price is usually decided at the very end. Answer buyers’ questions quickly: a clear reply can turn a visitor into a bidder.

Step 5: ship within 3 days and get paid

When the buyer pays, Catawiki lets you know and you have 3 working days to ship the object or get it ready for collection. You can set your own shipping costs per destination or use Catawiki’s smart shipping, which generates tracked labels and, according to the platform, can cost buyers up to 35% less.

Your money is released within three days of delivery and paid out according to the payment frequency you choose in your settings. The buyer is protected, but so are you: nobody takes your object without paying for it first.

What Catawiki charges sellers

Catawiki charges a seller success fee of 12.5% of the sale price plus a fixed amount, with VAT on top. If the object doesn’t sell, you pay nothing.

A rough example: if your object sells for €200, 12.5% is €25, plus the fixed amount and VAT. Terms can change, so always check the current ones on Catawiki’s seller pages before you start.

Tips from a seller

• Photos, photos, photos. Natural or diffused light, a neutral background, several angles and the details. For small objects, a macro shot and something for scale make all the difference. We photograph every nugget in macro and always state its exact weight.
• Exact data. Size, weight, origin, condition and flaws. What you leave out creates doubt; what you state and turns out wrong creates complaints.
• A realistic reserve, or none if the object is in demand: lots without a reserve usually attract more bids.
• Flawless shipping. Sturdy packaging, a tracking number and speed. Your buyers’ reviews are your best advertising.
• Consistency. Listing regularly makes buyers follow you and come back.

If you sell nuggets or other small objects, gold nugget sizes and weights shows why the exact weight matters so much to buyers.

Is it worth it?

For collectibles with an international audience, in our experience, yes: Catawiki puts your object in front of buyers from many countries, handles the payment and protects both sides. In exchange, it takes its fee and expects careful descriptions.

If you want to give it a go, you can register as a seller and submit your first object for free from the buttons on this page. And if you would rather buy, start with how to buy on Catawiki or read our review of whether Catawiki is legit.
