If your e-commerce checkout only offers credit and debit cards, you are not just limiting your audience—you may be turning away potential customers. In today’s global digital economy, a one-size-fits-all payment strategy often leads to higher cart abandonment and slower business growth.
At Payfac Solutions, offering local payment options is a key part of helping merchants succeed internationally. We continuously test, track, and analyze how different payment methods affect cross-border conversion rates.
In this article, we explain how we test the impact of international payment methods and how a data-driven approach helps merchants improve their checkout performance.
Why Global Payment Methods Are No Longer Optional
Before discussing how we test payment strategies, it is important to understand why global payment options matter.
Payment preferences vary significantly across regions. Customers usually prefer payment methods they already know and trust.
Europe
In Europe, credit cards are common, but many countries still rely heavily on local payment systems. For example, Bancontact is widely used in Belgium, while bank transfer methods remain popular in Germany. Offering only card payments can limit conversions in these markets.
Asia-Pacific
Digital wallets are extremely popular across the Asia-Pacific region. GrabPay and GoPay are widely used in Southeast Asia, while Alipay and WeChat Pay dominate the Chinese market.
Latin America
Many consumers in Latin America rely on cash-based voucher systems, especially those who are unbanked or underbanked. Payment methods like Boleto in Brazil and similar voucher systems in Mexico allow customers to complete online purchases using cash.
Nordic Countries
Bank-based mobile payment solutions are common in Nordic countries. Apps such as Swish in Sweden and MobilePay in Denmark are integrated into everyday transactions.
When customers reach checkout and cannot find their preferred payment method, trust in the brand can decline. The result is often a cart abandonment, lost revenue, and a customer who may never return.
Our Approach to Testing the Impact on Conversions
At Payfac Solutions, we avoid relying on assumptions. Instead, we use a structured testing strategy to measure how local payment methods influence checkout performance.
Below is a simplified overview of our testing methodology.
1. Creating a Baseline: The “Before” Analysis
The first step is to examine the existing checkout performance for each new merchant partner, particularly those receiving international traffic.
We focus on several key metrics, including cart abandonment rates across different countries and regions.
For example, we ask questions such as:
- Are certain countries showing higher abandonment rates than the global average?
- Do regions like Brazil, Germany, or the Netherlands show signs of payment friction?
This baseline data acts as our control group, allowing us to measure conversion performance before introducing new payment methods.
2. Strategic Rollout of Payment Methods
Instead of adding every possible payment option at once, we take a targeted approach.
Adding too many options can make the checkout process complicated and make it difficult to identify which payment method actually improves conversions.
Our strategy involves two steps:
Traffic Analysis
We analyze which regions generate the most traffic or revenue for the merchant.
Payment Method Selection
For each region, we choose one or two payment methods that are most relevant to local customers.
For example:
- Adding iDEAL for customers in the Netherlands
- Introducing Boleto for Brazilian customers
The hypothesis might look like this:
“Adding iDEAL for customers in the Netherlands will reduce cart abandonment and improve conversion rates for that market.”
3. Using A/B Testing to Measure Results
Once a hypothesis is defined, we conduct controlled A/B tests to collect reliable data.
Visitors are randomly divided into two groups.
Group A – Control Group
This group sees the standard checkout process with only card payment options.
Group B – Variant Group
This group sees a modified checkout where the relevant local payment option is clearly displayed.
By splitting traffic randomly, we ensure that any difference in conversion rates between the two groups is directly related to the newly added payment option.
4. Analyzing the Results
After the testing period ends, we evaluate the results in more detail.
Our analysis focuses on several important metrics.
Conversion Rate Increase
We measure how many additional purchases were completed by the test group compared to the control group.
Impact on Average Order Value (AOV)
We also analyze whether customers using the new payment method tend to spend more or less.
In many cases, reducing checkout friction encourages high-intent customers to complete larger purchases, which can increase the average order value.
New Customer Acquisition
Another important metric is how many transactions were made by first-time customers using the new payment option.
Local payment methods often attract customers who previously abandoned their carts.
Return on Investment (ROI)
Finally, we compare the revenue increase against the cost of integrating and processing the new payment method. In most cases, the results show a positive return on investment.
What Our Experiments Showed
After testing payment strategies with hundreds of merchants, we consistently observed clear results.
Double-Digit Conversion Growth
Adding just one relevant local payment method often increases conversion rates by 15% to 30% in key markets. In some cases, the improvement is even greater.
Reduced Cart Abandonment
When customers can pay using familiar payment methods, checkout friction decreases significantly. Faster and simpler payments lead to more completed transactions.
Increased Market Reach
By supporting local payment options, merchants can enter new markets more effectively. Using the “local payment language” helps businesses compete more easily in international regions.
Stronger Customer Trust
Displaying familiar payment logos throughout the checkout process helps customers feel more confident about completing a transaction.
How Payfac Solutions Helps Merchants Apply These Insights
Running these tests independently can be complex and time-consuming. At Payfac Solutions, this data-driven approach is built directly into our services.
Onboarding Analysis
When merchants start working with us, we begin by analyzing their traffic data and sales performance. This helps us develop a customized payment strategy.
Simplified Integration
We provide a single payment gateway that simplifies the integration of multiple international payment methods.
Continuous Optimization
The payments landscape changes constantly. Our team monitors performance data and recommends when new payment options should be added or when existing methods should be adjusted.
This strategy is particularly important for merchants operating in complex sectors. High-risk merchant accounts in the UK and international markets require reliable payment infrastructure to ensure stable transaction processing and long-term growth.
Stop Guessing and Start Converting
The question today is no longer whether businesses should support international payments. The real question is which payment methods should be offered and how they should be implemented.
The impact of global payment options on conversion rates is measurable and significant. For businesses involved in global e-commerce, payment flexibility is no longer optional.
By using a data-driven testing approach, Payfac Solutions helps merchants transform their checkout process from a point of abandonment into a powerful driver of international growth.
