To sell in multiple currencies with Klarna, you need a currency switcher plugin. In this guide, we’ll walk you through how to get started with selling in USD and EUR using Klarna for WooCommerce. Throughout the guide, we’ll assume that you are a US-based store that also wants to sell to customers in Germany.

We use FOX – Currency Switcher Professional for WooCommerce (free), which supports two currencies – ideal for USD and EUR. You can add more currencies in the Premium version.

Another common option is Aelia Currency Switcher.

This guide will show you how to:

• Configure FOX Currency Switcher Professional for USD and EUR
• Enable Klarna for WooCommerce and ensure payments work in multiple currencies

FOX Currency Switcher Professional

1. Requirements

You will need:

• WooCommerce
• FOX Currency Switcher Professional – read more here
• WooCommerce BACS setup (for testing payments)
• Klarna for WooCommerce (added later)
• Klarna accounts enabled for both USD and EUR

2. Enable Direct Bank Transfer (BACS)

Start by verifying that currency switching works before enabling Klarna.

Activate Direct Bank Transfer (BACS) in WooCommerce and confirm that currency switching works correctly. Once this is verified, you can enable the Klarna plugin. This approach makes troubleshooting easier.

Go to WooCommerce → Settings → Payments → Take offline payments and set up Direct bank transfer.

3. Install FOX Currency Switcher Professional

1. Go to Plugins → Add New
2. Search for “FOX Currency Switcher Professional”
3. Install and activate the plugin

The free version supports a maximum of two currencies – perfect for USD + EUR. The paid Premium version enables you to add additional currencies.

4. Currency settings

4.1 Select selling countries and default currency

In our example, the store sells to both the US and Germany.
WooCommerce only supports one default currency, which in this case is USD.

You set this under WooCommerce → Settings → General and scroll down to Currency options.

4.2 Add USD and EUR in FOX

Add both currencies in the FOX Currency Switcher settings and ensure they are enabled.

5. Display the currency switcher in the store

1. Go to the plugin’s display settings
2. Enable the side currency switcher or your preferred widget
3. Save the settings

Your customers can now switch currencies in the store.

6. Test FOX with WooCommerce BACS

Perform test purchases in both USD and EUR to confirm that currency switching works properly.

7. Enable GeoIP (optional)

FOX can automatically select a currency based on the visitor’s location using GeoIP.

8. Install and activate Klarna for WooCommerce

Follow this guide to get started in test mode: Set up Klarna Payments for test purchases.

9. Confirm that Klarna is available for the US and Germany

Make sure your Klarna agreements include the countries and currencies you want to sell in.

Also make sure you have correctly configured the Credentials in Klarna for WooCommerce.

10. Test Klarna in USD and EUR

For Klarna to appear as a payment option, the country and currency must match an active agreement on your Klarna merchant account.

A list of available countries, locales, and currencies for Klarna Payments can be found at the Data mapping settings in the Klarna Docs.

If you’re unsure about your agreements, contact the Klarna merchant support.
