Does Klarna Work with Shopify? Integration and Setup Guide

Introduction

Klarna is fully compatible with Shopify and remains one of the most popular Buy Now, Pay Later (BNPL) integrations for merchants globally. By enabling this payment option, you allow your customers to split their purchases into manageable installments or pay at a later date, which directly influences conversion rates and average order values. While the integration is straightforward, managing how and when these options appear at your checkout requires a strategic approach.

Our tool, Try HidePay on Shopify, helps you maintain this control by allowing you to define exactly which customers see Klarna based on their location, cart size, or order history. This guide covers everything you need to know about setting up the integration, understanding regional availability, and optimizing your checkout experience for maximum profitability.

Whether you are a high-volume retailer or a growing dropshipping store, understanding the nuances of this integration is the first step toward a more flexible checkout. You will learn how to connect your accounts, configure the settings in your Shopify admin, and implement rules that protect your margins.

Understanding the Klarna and Shopify Integration

Klarna operates as a third-party payment provider that integrates natively with the Shopify ecosystem. For most merchants, this means the setup does not require complex coding or manual script edits. The integration is handled either through Shopify Payments or as a standalone alternative payment provider, depending on your store's primary currency and the region where your business is registered.

If you want a deeper look at how HidePay fits into Shopify checkout optimization, see our post, Introducing HidePay for Shopify, which covers common use cases and examples.

When you offer this payment method, Klarna takes on the credit risk. They pay you upfront for the full order amount (minus their transaction fee), and the customer pays Klarna over time. This setup is particularly effective for stores selling high-ticket items, such as furniture, electronics, or premium apparel, where the upfront cost might otherwise lead to cart abandonment.

There are two primary ways to facilitate this connection. The most common method for modern Shopify stores is through Shopify Payments. In supported regions, you can simply toggle the option within your existing payment settings. If you are in a region where this is not yet supported, or if you prefer to keep your accounts separate, you can install the official app from the Shopify App Store and connect it as an alternative payment method.

Method 1: Using Shopify Payments

If you already use Shopify Payments as your primary gateway, adding BNPL options is often a one-click process.

1. Navigate to the Settings menu in your Shopify admin.
2. Select Payments.
3. In the Shopify Payments section, click Manage.
4. Scroll down to the Wallet and Local Payment Methods section.
5. Find the relevant BNPL option and check the box to activate it.
6. Click Save.

Once activated, the system automatically determines which payment options to show the customer based on their location and the currency of the transaction.

Method 2: Standalone App Integration

If you prefer a direct account or are in a region where Shopify Payments does not include these options, follow these steps:

1. Create a merchant account directly on the provider's website.
2. In your Shopify admin, go to Settings and then Payments.
3. Navigate to Additional Payment Methods and click Add Payment Methods.
4. Search for the provider by name and select it.
5. Install the official integration app when prompted.
6. Enter your API credentials (usually a Client ID and Secret) provided in your merchant portal.
7. Activate the service and perform a test transaction to ensure the connection is live.

Regional Availability and Requirements

Before starting the setup, verify that your business is located in a supported region. Currently, the integration is most robust in the United States, the United Kingdom, Canada, and several European markets including Germany, Sweden, Norway, Denmark, Finland, the Netherlands, Austria, and Switzerland.

Each region may offer different products. For example, "Pay in 4" is the standard in the US, while "Pay in 3" is more common in the UK. In European markets like Germany, "Pay in 30 Days" (invoice payments) is a dominant consumer preference. Your store must be configured to accept the local currency of the region where you wish to offer these options. If you sell internationally, Shopify Markets allows you to present the correct local payment options to customers based on their shipping address.

To qualify for an account, your business must meet certain criteria set by both Shopify and the payment provider. This typically includes having a clear return policy, accurate product descriptions, and a history of reliable shipping. High-risk industries may face additional scrutiny or may be ineligible for certain financing products.

How to Set Up Klarna on Shopify

The setup process varies slightly depending on whether you are using Shopify Payments or a standalone integration. Below is the general workflow for both scenarios.

Method 1: Using Shopify Payments

If you already use Shopify Payments as your primary gateway, adding BNPL options is often a one-click process.

1. Navigate to the Settings menu in your Shopify admin.
2. Select Payments.
3. In the Shopify Payments section, click Manage.
4. Scroll down to the Wallet and Local Payment Methods section.
5. Find the relevant BNPL option and check the box to activate it.
6. Click Save.

Once activated, the system automatically determines which payment options to show the customer based on their location and the currency of the transaction.

Method 2: Standalone App Integration

If you prefer a direct account or are in a region where Shopify Payments does not include these options, follow these steps:

1. Create a merchant account directly on the provider's website.
2. In your Shopify admin, go to Settings and then Payments.
3. Navigate to Additional Payment Methods and click Add Payment Methods.
4. Search for the provider by name and select it.

Strategic Benefits of Offering BNPL

Adding flexible payment options is more than just a convenience; it is a strategic move to grow your business. Merchants who implement these solutions often see an immediate shift in customer behavior.

Increased Average Order Value (AOV)

When customers know they can split a $500 purchase into four installments of $125, the psychological barrier to completing the purchase lowers. This often encourages shoppers to add more items to their cart or opt for a higher-end version of a product. Data consistently shows that BNPL options can increase AOV by up to 40% in certain industries. For related tactics on boosting AOV, see our article on Multiscount.

Reduced Cart Abandonment

A major cause of cart abandonment is "sticker shock" at the final checkout page. By presenting the installment price early in the shopping journey—and ensuring it is available at the final step—you provide a financial safety net for the customer. This transparency builds trust and keeps the customer in the checkout flow. To remove cluttered or confusing buttons that increase abandonment, learn how to hide dynamic checkout buttons with HidePay.

Customer Acquisition

Many shoppers specifically look for stores that offer their preferred financing method. In fact, some consumers use the provider's own app as a search engine to find brands that support their platform. By integrating this into your Shopify store, you tap into a massive ecosystem of pre-approved shoppers who are ready to spend.

Optimizing Your Checkout Experience

Simply enabling a payment method is not enough. To truly master your checkout, you must control how these options are presented. A cluttered checkout with too many buttons can overwhelm a customer, leading to "decision paralysis."

This is where the rules within HidePay become essential. Instead of showing every possible payment method to every customer, you should use logic to surface the most relevant ones. For a step-by-step walkthrough on building these rules, see how to create a payment customization.

For example, if a customer is buying a $10 gift card, offering a financing plan is unnecessary and adds clutter. You can set a rule to hide BNPL options for any cart total below a specific threshold, such as $50.

Sorting for Conversion

The order in which payment methods appear matters. Most customers will choose the first or second option they see. If your goal is to push users toward credit card payments to avoid BNPL fees, you should sort those to the top. Conversely, if you are running a promotion to increase AOV, you might want to move financing options to the primary position. Learn how to sort and rename payment methods in HidePay.

Renaming for Clarity

Sometimes the default labels provided by payment gateways are not clear to every customer segment. Our app allows you to rename these methods. You might change a generic "Pay Later" label to something more descriptive like "Pay in 4 Interest-Free Installments" to ensure the customer understands the value proposition immediately. If a label is missing or behaves unexpectedly, use the guide to retrieve the correct payment method before renaming.

Managing Risks and Protecting Margins

While BNPL options increase sales, they also come with higher transaction fees than standard credit card processing. As a merchant, you must balance the increased conversion rate against the cost of the service.

If you sell products with very slim margins, the 5% to 6% fee typically associated with financing might be too high. In these cases, you can use geography or product-based rules to limit where these options appear. For example, you might choose to hide these payment methods for specific low-margin product categories while keeping them active for your high-margin flagship items.

Furthermore, consider the implications for returns. When an order placed via a financing plan is returned, you are still responsible for the original transaction fee in most cases. By using custom rules to only show these options to "high-trust" customers—such as those with a specific customer tag or a history of successful orders—you can mitigate the risk of high-volume returns. See how to hide payment methods by customer tag to implement this approach.

Advanced Use Cases for Shopify Merchants

Customizing your checkout requires looking at your specific business model. Here are three common scenarios where controlling payment visibility is beneficial:

1. B2B and Wholesale Segments

If you run a hybrid store that serves both retail and wholesale customers, your payment needs vary wildly between the two. Wholesale buyers usually pay via bank transfer or net-30 terms and should not see consumer BNPL options. You can use customer tags to hide financing methods for anyone tagged as "Wholesale," ensuring a professional and relevant experience for your business clients.

2. High-Risk or High-Fraud Regions

If you notice a spike in fraudulent activity or payment disputes from specific zip codes or provinces, you may want to restrict flexible payment options in those areas. By setting a rule based on the customer's shipping address, you can automatically hide Klarna for those specific regions, forcing the use of standard credit card payments where fraud detection might be more robust.

3. Subscription Products

Most BNPL providers have specific rules regarding recurring billing. If your store sells both one-time purchases and subscriptions, the checkout can become confusing if a customer tries to use an unsupported payment method for a subscription. You can create a rule to hide specific payment providers if the cart contains a product with a "subscription" property, preventing technical errors and customer frustration.

The Technical Foundation: Shopify Functions

HidePay is built on native Shopify Functions, which represents the modern standard for checkout customization. Previously, merchants had to rely on the Shopify Script Editor, which was limited to Shopify Plus users and often required complex Ruby coding. For background on the shift from Scripts to Functions, read Why Shopify Functions are the future.

Because we use Shopify Functions, the logic runs natively within Shopify's infrastructure. This ensures that your checkout remains fast and reliable, even during high-traffic events like Black Friday. There are no external scripts to slow down page load times, and the integration remains compatible with all future Shopify updates. This "native-first" approach is why our app maintains a high performance standard and is certified as "Built for Shopify."

Action Steps for Merchants

• Audit your current fees: Compare the transaction costs of your various payment gateways to identify which ones are the most expensive.
• Identify your "Sweet Spot": Determine the cart value where financing options become most effective for your AOV.
• Clean up your checkout: Use our tool to hide irrelevant options for low-value carts or specific regions.
• Test and reorder: Move your preferred payment methods to the top of the list and monitor if your conversion rate improves.
• Review regional labels: Ensure the names of your payment methods are localized and clear for your primary markets.

By taking these steps, you move beyond a simple "plug-and-play" setup and begin treating your checkout as a conversion-optimized asset.

Conclusion

Integrating Klarna with Shopify is a proven way to meet customer expectations and drive higher sales. By offering the flexibility of Buy Now, Pay Later, you remove financial barriers and build a more inclusive shopping experience. However, the key to a truly successful store lies in how you manage those options.

Using HidePay for sorting, renaming, and hiding payment methods allows you to create a streamlined, high-converting checkout that protects your margins and serves your customers exactly what they need.

FAQ

Does Klarna charge merchants a fee on Shopify?

Yes, like all payment processors, Klarna charges a transaction fee. This fee is typically higher than standard credit card processing because the provider assumes the credit risk and pays the merchant upfront. You can view your specific rates within your merchant portal or Shopify Payments settings.

Can I hide Klarna for certain products?

Yes, using our app, you can create rules to hide Klarna based on specific products or collections. This is useful for digital goods, subscriptions, or low-margin items where offering financing might not be cost-effective for your business.

Why is Klarna not showing up at my checkout?

This usually happens if the customer's currency or shipping country does not match the regions supported by your account. It can also occur if the cart total is outside the minimum or maximum limits set in your merchant configuration.

How do I change the order of payment methods on Shopify?

Shopify does not allow you to reorder payment methods natively in the admin. However, by using HidePay, you can easily sort and reorder your checkout options to ensure your preferred payment methods appear at the top. See the HidePay help guide on how to sort and rename payment methods for step-by-step instructions.
