Payment Solutions

Payment Solutions

This article explains how to set up payment solutions in your Mystore online store. We cover Klarna/Kustom, Vipps, and Adyen – application process, required documentation, and fees.

General information about payment solutions

There is no extra monthly cost or setup fee for our payment solutions. You only pay a transaction fee for completed orders.

We recommend setting up Klarna/Kustom as early as possible, so you can offer both Klarna/Kustom and Vipps at checkout from the start.

In brief:

Klarna/Kustom

Before you apply

The following must be visible in the online store before you send the application:

• Company name
• Org. number
• Registered address
• Terms of sale
• Privacy
• Contact information (phone number and store's email address)
