Average order value

With payment options for shoppers to spread the cost of their order and our full buyer’s protection, shoppers get more security and spending power. Large orders become less scary.

Reduce admin costs

With a single contract, one contact point, one settlement note, and one payout, you will spend less time on admin and more time selling the right product to the right customer.

Minimize the risk

Klarna takes the full credit and fraud risk on all purchases for you, for all payment methods. Even when a customer makes a return, we cover the chargeback cost.

Drive traffic

Partnering with Klarna will increase your website traffic. Our strong brand and influencer collaborations speak to shoppers who are actively looking for retailers that offer our payment methods.

Own the checkout

Klarna Checkout is built to match your brand and you can adjust the design so that it fits seamlessly into your webshop. Your customer will stay on your page throughout the entire purchase experience.

Fitness Guru and Klarna

The simplicity of Klarna Checkout proved to be exactly what we needed for fitnessguru. With excellent results in the Nordics, Klarna Checkout was an obvious choice when we launched in the UK. The result wasn’t just higher conversion – especially on mobile – but also much less admin. That’s freed up time for what we love most: talking to our customers and focusing on selling great products.
