How it works.

Pay in 30 days is designed to make shopping easier for your customers.


Your customers learn that they can pay for their order after they receive it with Klarna. No interest or fees - ever.

At checkout

With simple top-of-mind info - no card details needed - the purchase is completed within seconds.

On shipment

The order is activated by the retailer and the customer’s payment period starts. No risk to you - you're paid upfront and in full.

Post purchase experience

Whether you’re a retailer or a shopper, we’ve got your back. We take full fraud and credit risk for sellers, while giving full protection to buyers. We also put the control in the hands of customers with the Klarna app – gathering all orders in a single place. Through the app, your customers can manage their purchases, chat with customer service 24/7 and even report returns. Two days before payment is due, we’ll send a friendly reminder for a hassle-free experience.

Making purchase decisions can be tough. Give your customers 30 days to make sure their order is perfect before they part with their money.
