Connect Klarna to Thinkific

Klarna is one of the original buy-now-pay-later platforms, but course platforms don't support it natively. CheckoutJoy connects your Klarna account to Thinkific (and other platforms like Kajabi and HighLevel) so you can offer flexible payment options to your customers.

What You'll Build

A checkout experience that offers Klarna's flexible payment options:

• Pay in 30 days
• Pay now in full
• Pay over time (instalments)

Students are automatically enrolled after payment, with all Thinkific automations triggered as normal.

Checkout Options

CheckoutJoy offers three ways to use Klarna with Thinkific:

Option 1: Embedded Widget

Embed a checkout widget directly on your Thinkific page. Best for custom checkout pages where you control the design.

Option 2: Product Checkout Page

A hosted checkout page ready to use as soon as you import your product. Share the link directly or link to it from your Thinkific site. Includes automatic VAT calculation and VAT number validation.

Option 3: Custom Checkout Page

A hosted page with full customisation — add testimonials, FAQs, and styled content. Use the checkout page builder to create a complete sales page.

To access: Go to Checkouts → Pages and create a new page with a template.

Automatic VAT Handling

CheckoutJoy detects customer location and automatically:

• Adds the correct VAT rate (e.g., 25% for Sweden)
• Validates EU VAT numbers for B2B sales
• Removes VAT for valid business purchases (reverse charge)
• Generates compliant invoices
