Selling on European marketplaces since 2018

How K6 earns

From your stock to your payout, in four steps.

You send the stock. It stays yours.

It goes to our warehouse in Rotterdam, then on to the marketplaces' fulfilment centres. K6 never buys it.
We sell it through our own accounts.

Listings, advertising within the budget you cap, customer service and returns. Nothing goes live without your approval.
When it sells, K6 earns a percentage.

A percentage of net sales: sales without VAT and returns. Your exact rate is in the Brand Review.
Twice a month, we pay you the net amount.

A live dashboard shows sales, costs and stock, and each month brings a specified statement.

No retainer · No setup fee · No hourly billing

Passed on one to one, without markup: marketplace fees, fulfilment and storage, your advertising budget, shipping and packaging. Listing content, A+ content and a brand store are optional one-off services, and the content stays yours. The first term is fixed before launch.

What a Brand Review looks like.

Stoppelkade, a fictional Dutch beard-care brand, asked about Amazon.de. The review says yes, but not quickly.

Amazon.de can work for Stoppelkade, but not quickly. Do not bring the full range or a big advertising budget yet. Test three products at a price that holds, with advertising capped from day one.

Per bottle	Amount
Price the customer pays	€21.95
German VAT (19%)	−€3.50
Amazon's sales fee (15% for beauty)	−€3.29
Amazon's shipping fee (large envelope, up to 4 cm thick)	−€3.09
Left after VAT and Amazon's fees	€12.07

Per bottle of Baardolie Ceder, 30 ml, on Amazon.de. Fees from Amazon's public fee pages on 29 September 2026. Not the brand's margin: it pays for advertising, our percentage and the brand's payout.

Advertising takes much of what is left.
