Hi. How can we help?

Pairing Retail POS (X-Series) with your Klarna Merchant Account

Klarna is not currently supported by Lightspeed Payments. To use Klarna, you'll need to create and connect an account with a compatible third-party payment processor.

  • If you're an existing Klarna merchant: Ensure you've signed an updated version of your Klarna contract that includes in-store service. Reach out to your Klarna representative to start this simple process.
  • If you're new to Retail POS and an existing Klarna merchant: Ensure you wait until your in-store MID has been created.

Retail POS customers in the United Kingdom, United States, Australia, and New Zealand can offer Klarna's Pay in 3 payment method in your physical store. Follow the steps below to connect your Klarna merchant account with your Retail POS store.

For any issues regarding connecting your Klarna merchant account to Retail POS, contact klarna@vendhq.com
