Klarna On‑Site Messaging

Sell more with personalized payment offers

Klarna has been taking the friction out of payments since 2005 for over 90 million consumers globally, allowing shoppers to pay later in interest-free installments as an easy, flexible alternative to credit. Over 12,000 Shopify merchants are already using the On-Site Messaging App to continue that smooth journey, increasing risk-free sales through tailored messaging and showing your customers available payment plans while they’re still shopping.

On-Site Messaging is easy and simple to integrate. The app provides customized messaging ranging from banners promoting your partnership with Klarna and availability of payment options, to personalized promotions on product or cart pages. Advertising the ability to buy now and pay later before checkout improves sales

Let your customers know instantly how they can pay before they buy

Consumers are not always aware of the different payment plans available to them before reaching checkout. Knowing they can shop now and pay later, or split into installment payments prior to checkout, influences the purchase decision and is a way to affirm their spending power. Not just to buy, but also how much to spend.

While customers can pay over time Klarna pays you upfront. Your business is fully protected from fraud and credit risk, and shoppers are safe too.

Capitalize on payment preferences

Payment preference is highly personal. Payment preference and communication influences the likelihood of a customer completing a purchase. The On-Site Messaging app tailors messages to previous Klarna users based on their specific preferences and the products they are looking at, while new users are informed about what payment options are available to buy the goods in which they’re interested.
