Information on the Klarna payment method for online payments.

We also offer Klarna for in-store payments (via QR code)


Klarna allows the customer to shop online or in-store and to pay later. It gives flexible payment options, making it easier for them to shop. Klarna’s payment options include direct payments, pay after delivery options and installment plans, that allow consumers to pay when and how they prefer to. When your customers choose to pay with a Klarna payment option, Klarna collects the payment from the buyer whenever he chooses to pay, whether that be in 30 days, 3 or even 36 months.

Some of the main benefits of offering Klarna as a payment method are:
