Integrate Klarna into Shopify in 2025 quickly and easily
Reading time: 5 minutes
Klarna is one of the most popular payment providers for online stores in 2025 and with Shopify Payments is child's play to set up. So if you're thinking about setting up Klarna for your Shopify store, you've come to the right place. Here I'll show you how to integrate Klarna into Shopify. But first, the advantages of Klarna.
Why you should offer Klarna in your Shopify store
One of the main causes of abandoned purchases in the checkout process is a lack of payment options. To keep your conversion rate as high as possible, you should offer as many payment options as possible.
If you're still not convinced, you can take a look at your Shopify dashboard. If the number of abandoned purchases after checkout is higher than 30%, it could be due to a lack of payment options.
What makes Klarna so popular?
Klarna offers flexible payment options, including immediate payment, purchase on account and payment by installments. Paying later is particularly in tune with today's zeitgeist. Thanks to this flexibility, nothing stands in the way of immediate consumption.
But this also entails risks; in the past, retailers had to worry about their payment if they offered purchase on account. Today, Klarna takes care of collecting the money as a third-party provider. As a Shopify merchant, you receive the money immediately.
| Method of payment | Description | Target group | Advantages |
| Klarna Pay Later | Buy now, pay 14-30 days later (interest-free). | Customers who wish to pay later. | Interest-free, no immediate debit. |
| Klarna Slice It | Monthly installment payments for larger amounts. | Customers who want to pay for large purchases in installments. | Installment payment for more expensive products. |
| Klarna Pay Now | Direct payment by bank transfer, card or direct debit. | Customers who want to pay immediately and easily. | Instant payment for easy payment flow. |
| Klarna Financing | Flexible financing over a longer period, often interest-bearing. | Customers who want longer and flexible installments. | Flexible repayment, promotes willingness to buy. |
Klarna fees with Shopify Payments
If you set up Klarna with Shopify Payments, there are no additional fees. You only pay the Shopify Payments fee. So there's nothing wrong with setting up this payment method.
Disadvantages of Klarna
Klarna also comes with certain disadvantages. Since Klarna bears the full risk, they use a strict fraud protection process, which is why customers are repeatedly rejected.
In addition, the payment process is very lengthy and a lot of information is requested from the customer. Both can have a negative impact on the conversion rate.
