Klarna offers a simple and highly adaptable Buy Now Pay Later (BNPL) payment option, crafted to simplify financial transactions.

Allow your customers to pay how and when they want. Increase your sales, boost the average order value, and ensure customers return more frequently.


How it works

When choosing Klarna payment, we redirect the customer to the Klarna checkout page, that way, the customer just puts the card info and makes the payment. As soon as the payment has been done, the customer will be redirected to Paybyrd's system, where we will check the transaction status and tell the good news: "Your payment was a success".


Klarna provides the following payment methods:

Payment in 30 Days

Allows your customers to try out their items with an additional 30 days to complete the payment.

Financing

Gives your customers the flexible option to buy now and spread the cost over monthly payments.

Payment in 3 times

Offers your customers a modern alternative to credit: lets them pay later in 3 interest-free installments.

Working with Shipping

There are two ways to send the shipping fee:

  1. Add a shopping cart item as ShippingFee when creating the order.
  2. In the shopping cart item, fill in the amount in the shipping property **This amount will be sent if there is no ShippingFee item in the cart
