The commission fee for sellers is 12.5% of the winning bid, excluding VAT. Commission fees are used for extensively promoting our auctions. Your lots will be promoted in several ways: through online advertisements, social media, emails and print advertising, to name a few.

Catawiki will promote your lots via multiple online advertising platforms - Google, Facebook, and our partner network of blogs and themed websites.

What can I sell at Catawiki's online auctions?
Every week we organise over 300 auctions across 80 categories and we’re always looking for special objects to include in our auctions. These are the kind of objects that carry emotion, hold historical or cultural value or are objects of interest that will capture the attention of our audience. We welcome objects in a wide variety of categories, from watches to art, from curio to stamps, and from wine to classic cars.
How can I tell if my objects are suitable for Catawiki?
Whatever your special objects are, our in-house experts would be happy to review them for inclusion in our auctions. In certain categories, we ask for a minimum estimated lot value. This is because our buyers come to Catawiki in search of something not only out of the ordinary, but also of value. If you want to offer up objects with low estimated values, we suggest to group them and sell them as a collection.
