  • Protect your brand -  The Klarna Payments widget can be customised to match the look and feel of your website; with two possible levels of customisation.
  • No risk for you - Klarna assumes all credit and fraud risk, so that you don’t have to, and makes sure that you receive your money for ordered goods.
  • Encourage conversion - Offering shoppers a chance to pay for their purchase in instalments, with time scales and payment levels that suit them, can make the difference between making and losing an online sale.
  • PCI Complaince - All purchase details occur inside our iframe, reducing the PCI scope on your site.

  • Extra protection - Consumers are covered by Klarna’s Buyer Protection which guarantees they only pay for goods they receive and keep.
