Why look beyond Klarna
Klarna is a significant player in the buy now, pay later (BNPL) market, facilitating flexible payment options for consumers and providing merchants with tools to increase conversion rates and average order values. Its core offerings, such as Pay in 4 and Pay in 30 days, are widely adopted in e-commerce. However, businesses may explore alternatives due to various factors. Some merchants might seek lower transaction fees or more transparent pricing structures, as Klarna's rates can vary by product and country. Others may require a BNPL provider that integrates more seamlessly with their existing payment gateways or e-commerce platforms, or offers a broader suite of financial services beyond BNPL.
Additionally, some businesses may prioritize providers with different risk assessment models, aiming to minimize fraud or better manage chargebacks. The geographical availability and regulatory compliance of BNPL services also vary, prompting businesses operating in specific regions to look for local specialists. Finally, businesses with niche customer bases or unique checkout flows might find that other providers offer more customizable solutions or a better fit for their specific merchant and consumer needs.

How to pick
Choosing the right buy now, pay later (BNPL) or payment solution involves evaluating your business needs against the features and capabilities of each alternative. Consider these decision points:
-
Assess your primary objective:
- If your main goal is to offer interest-free, short-term installments, similar to Klarna's Pay in 4, then Afterpay or PayPal Pay Later with its Pay in 4 option are strong contenders. Afterpay is particularly effective for attracting a younger, fashion-focused demographic, while PayPal leverages its existing vast user base.
- If you need to facilitate larger purchases with longer-term financing options, potentially with interest, Affirm is specialized in transparent installment loans. Klarna also offers financing options, making it a direct competitor in this segment.
-
Consider your existing payment infrastructure:
- If you already use PayPal for processing, integrating PayPal Pay Later is often the path of least resistance, leveraging your existing setup and reducing integration effort.
- For businesses built on Shopify, utilizing Shopify's native BNPL integrations, such as Shop Pay Installments through Shopify Payments, offers seamless functionality and a unified management experience.
- If you require a comprehensive payment processing platform that can integrate multiple BNPL providers alongside other payment methods, Stripe or Adyen provide the flexibility and global reach needed to manage diverse payment ecosystems from a single API.
- Small and medium businesses using Square for POS and online sales will find its integrated BNPL options to be a convenient extension of their existing services.
-
Evaluate your customer base and geographical reach:
- If your customer base is primarily in the US and Canada, Affirm is a strong choice.
- For a broader international presence, particularly in Europe, the US, and Australia, Klarna remains competitive, but Adyen offers unparalleled support for localized payment methods globally, including various BNPL options specific to regions.
- Afterpay has strong traction in the US, Canada, Australia, New Zealand, and the UK.
-
Examine pricing models and transaction fees:
- Compare the transaction fees, setup costs, and any recurring charges across providers. While most BNPL providers charge merchants a percentage per transaction plus a fixed fee, the exact rates can vary significantly. Some providers may also have different rates depending on the BNPL product (e.g., interest-free vs. interest-bearing loans). Request detailed pricing from each alternative based on your anticipated transaction volume and average order value.
-
Consider fraud prevention and risk management:
- BNPL services shift credit risk from the merchant to the provider, but understanding each provider's approach to fraud prevention and chargeback policies is crucial. Platforms like Stripe and Adyen offer advanced fraud detection tools as part of their broader payment platforms, which can be beneficial if you're consolidating payment processing. Specific BNPL providers like Klarna and Affirm also have their own robust fraud prevention systems.
