As opposed to Klarna Checkout, Payments are standalone payment methods. Complement your existing checkout experience with a Klarna hosted widget (e.g., Pay Later, Financing or Installments).
Choose the Klarna features you want – and only the features you want – to reduce purchase stress and improve your user experience. We have several financing and direct payment options to meet your needs, and they’re all easily integrated into your existing buying journey.
Pay Now (direct payments)
Customers who want to pay in full at checkout can do it quickly and securely with a credit/debit card.Friction-free direct purchases while maximising the value for your business thanks to guaranteed payments. If they have a Klarna account they can save their details and enjoy one-click purchases from then on.
Pay later (invoice)
Try it first, pay it later. Delayed payments for customers who like low friction purchases and to pay after delivery.
Slice it (installments)
Installment, revolving and other flexible financing plans let customers pay when they can and when they want.
How to Get Started
- Sign up for Klarna.
- Install the plugin on your site. During this process you will be asked to download Klarna Order Management so you can handle orders in Klarna directly from WooCommerce.
- Get your store approved by Klarna, and start selling.
What’s the difference between Klarna Checkout and Klarna Payments?
Klarna as your single payment provider keeps everything under one roof. You’ll have one agreement, one point of contact, one settlement file, one payout with Klarna Checkout. It only takes a single integration to deliver the full Klarna hosted checkout experience through a widget placed on your site.
Klarna Payments removes the headaches of payments, for both consumers and merchants. Complement your checkout with a Klarna hosted widget located in your existing checkout which offers payment options for customers with a smooth user experience.
- Upload plugin folder to to the “/wp-content/plugins/” directory.
- Activate the plugin through the “Plugins” menu in WordPress.
