Swedish Buy Now, Pay Later (BNPL) giant Klarna has secured a major global partnership with Stripe, a leading Irish-American financial infrastructure provider.

Through this collaboration, Klarna Stripe partnership will leverage Stripe’s extensive platform to deliver flexible payment solutions across 26 countries. Merchants using Stripe will benefit from seamless integration of Klarna’s BNPL options, driving higher conversion rates and increased average order values by offering customers enhanced payment flexibility.

Key Takeaways

• With this partnership, Klarna gets access to Stripe’s millions of merchants across 26 countries. This expanded distribution will give Klarna a significant boost in establishing a global footprint and will also help accelerate merchant adoption – which became evident by a reported doubling of new merchant sign-ups in recent quarters.
• This deal will leverage Stripe’s unified payment infrastructure, which means businesses will be able to add Klarna’s BNPL options without extra coding or onboarding. Merchants can quickly test and deploy Klarna’s payment solutions and further improve checkout conversions and overall sales performance.
• Klarna and Stripe’s deal is structured strategically to drive incremental revenue for both companies. Merchants adding Klarna’s flexible payment plans are seeing as high as a 14% revenue increase and higher average order value. Additionally, shared transaction revenue models align growth incentives for both companies.

Klarna Stripe Joins Forces to Expand Payment Services

In the past decade or so, the payments ecosystem has experienced a paradigm shift in consumer payment preferences. Credit card models, which once dominated the market, are now being complemented (or even replaced) by more flexible payment options. BNPL has come out as the solution to cater to this evolving market demand by offering consumers a way to make purchases and pay them over time (usually in 4-6 months), without paying interest or fees.

Klarna has been the frontrunner in the BNPL space, offering consumers multiple payment options – including immediate payments, short-term interest-free installments, and longer-term financing – leading to lower cart abandonment rates and an increase in revenue. On the other hand, Stripe is a known financial infrastructure platform based in the US. The company offers a suite of tools that simplify payment processing, billing, and financial management. Stripe enables businesses to scale efficiently.

On January 14, 2025, Stripe and Klarna announced a strengthened global partnership enabling businesses on Stripe’s platform in 26 countries to instantly offer Klarna’s suite of payment options, ranging from immediate payments to buy now, pay later and longer-term financing. This new collaboration—launched in the fourth quarter of 2024—extends the initial October 2021 integration (which covered the United States and 19 European markets) to North America, Oceania, and two dozen European countries, putting Klarna’s flexible payment methods within reach of millions more merchants overnight.

Under the partnership, merchants integrating Klarna via Stripe can deploy flexible payment plans—including 3- or 4-installment interest-free schedules, 30-day pay-later options, and financing terms spanning 6 to 36 months—without credit or fraud risk, as Klarna indemnifies the merchant and pays them in full upfront.

This isn’t the first collaboration between Klarna and Stripe, the payments giant dual-headquartered in San Francisco. Previously, in 2021, during the fintech surge driven by the COVID-19 pandemic, Stripe integrated Klarna’s BNPL services for its merchants, though with more limited features.

Merchants can also offer their customers flexible payment options without complex implementations. Stripe has introduced a groundbreaking feature that enables businesses to instantly do A/B testing with various payment methods, such as Klarna, with no need for coding. The partnership follows Klarna’s sale last year of its Klarna Checkout business to an investor consortium.

Early adopters report measurable lifts in performance: merchants offering BNPL through Stripe see increased conversion and higher average order values, with revenue gains of up to 6.6% on Klarna-eligible sessions and up to 40% of Klarna-powered shoppers being new to their brand.

David Sykes, the Chief Commercial Officer of Klarna, highlighted the importance of their partnership, noting Klarna’s role as a vast global network linking 85 million active users with various retailers. He explained that expanding their retailer base enhances consumer attraction, creating a mutually beneficial cycle. Klarna’s goal is to ensure its payment solutions are ubiquitously available for every type of purchase, at any time. He regards Stripe as an ideal distribution ally, favored by both Fortune 500 corporations and the most innovative startups worldwide.

This deal is built on Stripe’s single-integration model—there’s no additional application, underwriting, or paperwork for eligible businesses—and leverages a unified dashboard for monitoring, reporting, and reconciliation. Stripe’s machine-learning engine dynamically surfaces the most relevant payment methods, ensuring Klarna’s options appear at optimal moments in checkout. The move follows Klarna’s June 2024 sale of its proprietary checkout platform (Klarna Checkout) to focus solely on its core, flexible payment services and eliminate channel conflict with PSPs like Stripe and Adyen.

Together, the two fintech giants bring colossal scale to bear: Klarna closed 2024 with 93 million active customers across 26 markets and $2.81 billion in revenue, while Stripe—valued at roughly $91 billion—processed $1.4 trillion in payment volume last year, making it the largest privately held fintech firm in the world. Their combined reach spans millions of merchants and tens of millions of consumers, creating a potent force multiplier for global commerce.

The timing of the enhanced integration dovetails with Klarna’s preparations for its long-anticipated U.S. initial public offering. Media reports suggest the company aims to raise over $1 billion at a valuation north of $15 billion, driven by robust 24% revenue growth in 2024 and a net profit of $21 million. That growth is underpinned by a BNPL market projected to exceed $160 billion by 2032, as major retailers and digital platforms partner with fintech pioneers to capture credit-averse consumers.

As Stripe cements its status as a top choice for both Fortune 500 companies and ambitious startups, the partnership leverages Stripe Connect to make Klarna available across platforms and marketplaces with zero integration lift for end users. While Stripe supports Klarna in 45 markets globally, the in-platform rollout specifically covers Australia, Canada, New Zealand, the United States, and 24 European jurisdictions. This frictionless distribution model positions Klarna “to make Klarna payments available everywhere, for everything, all the time” and equips merchants worldwide with best-in-class payment flexibility.

Instant transactions represent 30% of Klarna’s payment network, while the remaining transactions consist of interest-free Buy Now, Pay Later (BNPL) plans and extended financing. Klarna’s implementation of robust consumer protection safeguards has resulted in default rates significantly lower than traditional credit products, strengthening its position in consumer finance. Following Klarna’s sale of its Checkout business in 2023, Stripe began earning a share of transaction fees from integrated BNPL services, reflecting the growing merchant demand, as evidenced by a 172% increase in BNPL transaction volume on Stripe’s platform compared to traditional payment methods that year.

Since October 2024, Klarna has boarded 100,000 new merchants, doubling merchant adoption rates by the fourth quarter. Stripe’s Chief Business Officer, Jeanne DeWitt Grosser, emphasized that Stripe has streamlined Klarna’s integration, enabling businesses to increase revenues and offer consumers more flexible payment options.

Merchant services statements showing the credit card processing fees can be a minefield of numbers and jargon that sometimes you can‘t contemplate. As a business owner, you know that even the thinnest margins matter, and the cents and percentage points affect your profits at the end of the day.

To make things worse, hidden charges lurking behind the line items on your merchant statement put a hole in your pocket. While choosing the right, trusted, and most transparent option like Host Merchant Services should be your next step, it’s equally important that you are well-versed with the tricks that your current merchant service provider plays with you in the form of hidden fees.

Understanding Credit Card Processing Fees in 2025: Hidden Costs and Industry Changes

With technological advancements, newer (and more tailored) pricing models, and stricter regulations, credit card processing fees have become more complex. Merchant statements no longer show the standard interchange and assessment fees but also include a list of additional charges that, to be frank, most merchants tend to ignore.

While honest providers like Host Merchant Services emphasize transparency more in the payments industry, some hungry sharks roll on with the same old method despite promising to simplify the prices. 

These charges – often buried in the fine print – can include anything and everything, from transaction-based surcharges to recurring monthly costs. This is why understanding the actual cost of credit card processing is essential for merchants to remain competitive and profitable.

What Are the Usual Credit Card Processing Costs?

The costs to process a credit card vary depending on different factors like what industry you’re from, the transaction volume, and the payment method used. Typical fees range between 1.5% to 3.5% for each transaction.

The credit card processing charges also vary significantly depending on the card network the payer is using, for example:

• MasterCard charges 1.45% to 2.9% for every transaction.
• Visa charges 1.3% to 2.6% for every transaction.
• Discover charges around 1.55% to 2.45% for every transaction.
• AmEx charges 1.8% to 3.25% for every transaction.

Note that the rates can differ based on transaction method (whether the payer is swiping or entering the information manually), cardholder rewards program, or merchant category.

Factors Influencing the Overall Payment Processing Costs

Credit card transaction fees are influenced by various factors that can significantly impact the overall cost of payment processing for businesses. A comprehensive understanding of these factors enables merchants to manage expenses effectively and optimize payment systems.

1. Type of Card Used

The specific type of card presented during a transaction is crucial in determining the associated fees. Standard credit cards typically incur lower interchange fees than premium or rewards credit cards.

Premium cards often come with higher fees due to the additional benefits and rewards they offer cardholders funded through these increased fees. Similarly, business and corporate cards may attract higher fees than consumer cards.

2. Transaction Method

How a transaction is conducted—whether the card is physically present—affects the processing fees. Card-present transactions, such as those where the card is swiped or inserted into a terminal, generally incur lower costs due to the reduced risk of fraud.

In contrast, card-not-present transactions, including online or over-the-phone purchases, are deemed riskier and thus attract higher fees to compensate for the increased potential for fraudulent activity.

3. Merchant Category Code (MCC)

Each business is assigned a Merchant Category Code (MCC), a four-digit number that classifies the type of goods or services offered. The MCC can influence the interchange fees applied to transactions. Specific industries are considered higher risk and may be subject to elevated fees.

For example, sectors like entertainment or travel might face higher fees than retail businesses due to the perceived increased risk associated with their transactions.

4. Transaction Volume and Size

A merchant’s transaction volume and average size can impact the fees incurred. Businesses with higher transaction volumes may be able to negotiate lower rates with payment processors.

Similarly, merchants with lower sales volumes or smaller average transaction sizes might face higher fees. Additionally, fixed per-transaction fees can disproportionately affect smaller transactions, making them relatively more expensive on a percentage basis.

5. Payment Processor Pricing Models

The fee structure established by the payment processor also plays a significant role. Standard pricing models include interchange-plus, flat-rate, and tiered pricing. Each model has its cost implications, and the suitability of each depends on the specific transaction patterns of the business.

For instance, interchange-plus pricing offers transparency by separating interchange fees from the processor’s markup, which can benefit businesses that process a high volume of transactions.

6. Merchant’s Creditworthiness and History

A merchant’s financial stability and credit history can influence the fees set by payment processors. Businesses with firm credit profiles and a history of low chargeback rates may be offered more favorable terms, including lower costs. On the other hand, merchants with poor credit histories or higher instances of chargebacks might face higher costs to offset the perceived risk.

7. Regulatory Environment

Regulations governing payment processing fees can vary by country and region, affecting the costs incurred by merchants. For example, in the European Union, interchange fees are capped at 0.3% for credit card transactions and 0.2% for debit card transactions, leading to lower fees for merchants operating within the EU than those in regions without such caps.

What Are Hidden Fees?

Hidden fees are charges not disclosed during the initial contract or bundled into your monthly processing statement without proper explanation. They are “hidden” because they are either not discussed upfront by sales representatives or are obscured by complex billing structures.

Why Do Hidden Fees Occur?

There are several reasons behind the emergence of hidden fees:

• Lack of Transparency: Payment processors may bundle fees or use vague terminology, so the actual cost isn’t immediately evident.
• Contractual Complexity: Merchant agreements often include fine print detailing fees like early termination penalties or monthly minimums—charges that merchants might only notice when they review their statements.
• Revenue Maximization: Some processors intentionally obscure fee details to boost their profit margins. Merchant Cost Consulting notes that hidden fees are sometimes used to “double dip” on services merchants believe they are already paying for.
• Evolving Pricing Models: With the rise of tiered, flat-rate, and interchange-plus pricing models, understanding what you pay for each transaction can be challenging.

Common Hidden Fees on Your Merchant Services Statement

While some fees are unavoidable, many hidden costs can be negotiated or eliminated. Let’s examine the most common types of hidden costs that could appear on your merchant services statement in 2025.

1. Authorization and Transaction Fees

Two commonly referenced charges are authorization and transaction fees in credit card processing. An authorization fee is incurred each time a merchant submits a request to the cardholder’s issuing bank to verify the availability of funds for a transaction. This fee applies regardless of whether the transaction is approved or declined. Typically, minimal authorization fees range from $0.01 to $0.06 per transaction.

Transaction fees, sometimes per item, are charged when a transaction is completed and processed. This fee is applied only to successfully authorized transactions and compensates the payment processor for facilitating the payment. The structure and amount of transaction fees can vary depending on the payment processor and the specific agreement with the merchant.

While both authorization and transaction fees are standard in payment processing, merchants should be vigilant to ensure they are not being charged both fees for the same transaction in a manner that constitutes double billing. Some payment processors may implement pricing structures where both an authorization fee and a transaction fee are applied separately to the transaction, leading to higher costs for the merchant. This “double dipping” strategy may not be immediately evident unless you closely scrutinize your statement.

2. Statement Fees

You might expect to pay for processing transactions, but why should you pay extra to receive a statement? Some providers add a monthly fee to deliver detailed billing statements, even when delivered electronically. These fees can quickly add up over time and are often buried under generic terms like “account maintenance” or “service fees.”

3. PCI Compliance and Non-Compliance Fees

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security protocols to ensure merchants securely handle cardholder data during payment processing. Compliance with these standards is mandatory for businesses that accept credit or debit card payments.

Many payment processors impose PCI compliance fees to manage and validate compliance, which can vary significantly, typically from $20 to over $125 monthly. These fees often encompass services such as security assessments, vulnerability scanning, and assistance with the Self-Assessment Questionnaire (SAQ). However, the specific services included can vary between processors. The SAQ is a tool designed to help merchants self-evaluate their compliance with PCI DSS. It comprises a series of yes-or-no questions corresponding to the PCI DSS requirements. Completing the SAQ is a critical step in validating compliance, and many merchants can fulfill this requirement independently without incurring additional costs.

Merchants must be aware that some payment processors may continue to charge PCI compliance fees even after a merchant has completed the necessary steps to become compliant, such as filling out the SAQ and implementing required security measures. In some cases, processors may impose PCI non-compliance fees until compliance is validated. These practices can result in merchants paying for services they no longer need or for compliance validation that has already been achieved.

4. Early Termination Fees

Many merchant service contracts are long-term, and if you decide to switch providers before the contract ends, you could be hit with a hefty early termination fee. These fees are designed to lock you into a relationship with the processor and sometimes run into hundreds or thousands of dollars.

5. Monthly Minimum Fees

Even during slow sales periods, your processor may require you to meet a minimum processing volume. If your transaction volume falls below this threshold, you will still be charged as if you had met it. This can be particularly burdensome for seasonal businesses or startups with fluctuating sales.

6. Monthly Settlement or Batch Fees

Some providers charge fees each time they “settle” a batch of transactions—sometimes daily, and then an additional fee is added up at the end of the month. While a single batch fee may be small, the cumulative cost over many transactions and multiple days can be surprisingly high.

7. Refund Fees

When you process a refund, you might assume you reverse the transaction. However, many processors keep the interchange fee (or a portion) even if the money is returned to the customer. This means you may incur an additional fee you did not expect for every refund.

8. Annual Fees

Some payment processors charge an annual fee to maintain your merchant account. Although these fees are less frequent than monthly charges, they represent an additional cost that needs to be factored into your overall processing expenses.

9. “Padded” Assessment Fees

Credit card networks impose assessment fees on each transaction, but some processors add an extra “padding” fee on top of what is required. These small amounts might seem insignificant per transaction, but they can accumulate rapidly over time, particularly for high-volume businesses.

10. Terminal and Gateway Fees

If you operate a brick-and-mortar business, you may be charged a fee for using or leasing a credit card terminal. Similarly, if you process online payments, a gateway fee may be added to cover the cost of the software and infrastructure. These fees are sometimes not itemized on your statement, making it difficult to determine if you’re being overcharged.

11. Other Miscellaneous Fees

Several other fees may appear, such as setup fees, voice authorization fees, or even fees for services like fraud prevention or chargeback handling. Each fee may be small, but it can substantially burden your processing costs.

Why Hidden Fees Matter?

Hidden fees are more than just an annoyance; they can significantly impact your bottom line. Consider the following points:

• Eroded Profit Margins: Even a seemingly minor fee—an extra 0.5% on every transaction—can add up to thousands of dollars over a year, especially if you are a high-volume merchant.
• Reduced Cash Flow: Unexpected charges make it harder to predict monthly expenses, which can complicate budgeting and cash flow management.
• Competitive Disadvantage: If you’re overpaying on fees, you may be forced to raise your prices to maintain profitability, potentially driving customers to competitors.
• Lack of Transparency: When fees are hidden or obscured, it’s difficult for merchants to understand what they’re paying for. This lack of clarity can undermine trust and complicate negotiating better terms with processors.
• Regulatory Impact: With regulators and industry groups pushing for greater transparency, hidden fees may soon become a subject of legal scrutiny. Understanding these fees now can help you avoid potential compliance headaches later.

Strategies to Identify and Avoid Hidden Fees

Taking control of your merchant services statement is essential. Here are some practical strategies to help you identify and, if possible, avoid hidden fees:

• Review Your Statements Thoroughly

One of the simplest ways to combat hidden fees is to read your monthly statements line by line. Look for any charges that you don’t fully understand. Tools like the statement audit provided by EBizCharge can help you break down and analyze each fee.

• Calculate Your Effective Rate

Your effective rate is the percentage you pay on each transaction after all fees are considered. To calculate this, divide your monthly fees by transaction volume, then multiply by 100. This simple metric can help you spot discrepancies and compare your fees against industry benchmarks.

• Understand Your Pricing Model

Knowing whether you are on an interchange-plus, tiered, or flat-rate pricing model. Interchange-plus pricing is generally more transparent because it itemizes the base interchange and assessment fees separately from the processor’s markup. If you’re on a tiered pricing model, you may not have a clear view of what portion of your costs are avoidable. Gr4vy recommends opting for transparent pricing models to ensure you know exactly what you charge.

• Negotiate with Your Processor

Many fees, especially markups and monthly minimums, are negotiable. You can approach your processor to ask for adjustments with your practical rate calculations and a detailed understanding of your statement. If your current provider is not willing to negotiate, consider shopping around. Merchant Cost Consulting reports that up to 65% of merchants who negotiate can secure lower fees.

• Use Technology and Expert Assistance

Several companies now offer software tools that audit your merchant statement for hidden fees. For example, Swipesum’s Statement tool provides detailed insights into your processing costs and can flag unexpected fees. Consulting with a payments expert can help you understand your statement and advise on potential cost-saving measures.

• Keep Abreast of Regulatory Changes

In recent years, regulators have started to crack down on “drip pricing” and other practices that hide fees until the end of the checkout process. Familiarize yourself with any changes in regulations that may affect fee disclosures. This proactive approach protects you and puts you in a stronger position during negotiations with your provider.

Best Practices for Merchant Fee Management

The first step is knowing how to read your statement and understand hidden fees. Here are some best practices to help you manage your payment processing fees on an ongoing basis:

• Schedule Regular Audits

Regular audits of your merchant statement are essential. At least once every quarter, sit down with your financial team or a trusted advisor to review your fees in detail. Identify any new or unexpected charges and compare them with previous months.

• Benchmark Your Fees

Compare your effective rate with industry averages. Resources such as the NerdWallet guide on credit card processing fees and reports from payment service providers like DirectPayNet can give you a clear picture of what you should be paying. If your fees are significantly higher, it might be time to renegotiate or even switch providers.

• Educate Your Team

Ensure that the key members of your team, especially those in finance and operations, understand the fee structures and know how to read merchant statements. Training sessions or workshops can help demystify the numbers and empower your team to make informed decisions.

• Maintain Documentation

Record all contracts, statements, and any communications with your payment processor regarding fees. This documentation can be invaluable during negotiations or if discrepancies arise later. It also helps you track changes to see if hidden fees increase.

• Stay Flexible

The payments industry is dynamic. New technologies, regulatory changes, and emerging competitors can all affect fee structures. Remain open to changing your processing setup if it means better transparency and lower fees. Flexibility is key to staying competitive.

Conclusion

Hidden fees on your merchant services statement can quietly eat into your profits if you’re not paying close attention. While some charges are standard, others may be unnecessary or even avoidable with the right approach. Reviewing your statements regularly, understanding your pricing model, and negotiating with your provider can help minimize these costs.

Working with a transparent payment processor that prioritizes clear pricing can also make a significant difference. Staying informed and proactive about hidden fees ensures your business remains competitive and financially stable in 2025 and beyond.
