Klarna's main output is how it builds value-adding relationships with merchants by increasing conversion, average order value and sales while creating a superior consumer experience (e.g. integrating with ASOS to help you buy that pair of trainers before you get paid this month). It now operates globally, with over 400,000 merchants and over 147 million consumers.

Having dropped in value recently and announced a large round of job cuts, Klarna is facing some difficulties going forward. It also faces competition from Apple who are jumping into the buy now, pay later market, adding additional pressure on top of slower ecommerce growth and increased government regulation in this space. Klarna must effectively navigate this space in order to come out on top; however, given its market reputation and vast size, it certainly has plenty of opportunity to do so.
