Hi. How can we help?

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

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. 

If you are an existing Klarna merchant, make sure you have 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 are an existing Klarna but new to Retail POS merchant, make sure you wait until your in-store MID has been created. 

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