For businesses expanding from domestic markets to international audiences, one reality underpins every successful entry: they need international payment solutions that let customers in target countries pay with trusted local methods.
For example, in São Paulo, it is not unusual to see a customer buy a cup of coffee and pay in instalments. To outsiders, this behaviour feels counterproductive, but to a local, it is normal and reflects a broader financial habit.
For international businesses, that payment culture underscores why supporting local preferences matters far more than treating card payments as a one‑size‑fits‑all solution.
Across the globe, businesses think the most challenging part is getting a customer to click the “Add to Cart” button. For a global business, this assumption misses a crucial detail — if customers don’t see their preferred payment method, they will most likely abandon the purchase.
Thus, payment strategy should not be treated as a technical pipeline or a backend function that does not deserve as careful consideration as other parts of the business receive. Instead, it must be so well-crafted that it could even be treated as a marketing tool. When people have the ability to use their preferred payment method, businesses can increase customer willingness to complete their purchases, translating to millions of dollars in annual revenue.
This is also driven by trust, and trust looks different depending on where you live. A checkout page that relies solely on card payments may work well in some parts of the world, but may fail elsewhere. This is especially true if customers live in a country where credit cards are not common or perceive the limited payment options as unsafe.
To win these customers over, businesses need to build a structured understanding of the dominant financial culture in these countries. For instance:
Germany: Bank-led systems dominate. Shoppers will prefer to log into their trusted online banking app and complete their orders.
Southeast Asia: Mobile wallets define the landscape. Shoppers will expect to scan a QR code to initiate a payment.
Brazil: Credit-based financing and instalments are the rule. Shoppers expect to break their payments into monthly instalments.
The culture of a certain region shapes how its society behaves. A deep dive into the history, the prevalent culture, and the infrastructure of a country will help businesses to build a checkout that actually converts.
The e-commerce ecosystem of Brazil is built around two dominant payment methods: Pix (the country’s real-time payment network) and parcelamento (instalment payments). Merchants seeking to enter Brazil’s payment localisation should support both payment methods as they reflect the broader checkout experience that many locals expect.
Recent data from RankingsLatam tracking Brazil’s financial dynamics shows the sheer scale of this trend. The country’s credit card financing portfolio expanded to BRL 735.4 billion by late 2025. Concurrently, Pix has rapidly become one of the country’s favourites for instant bank transfers, attracting more than 150 million users.
In Germany, the payment system operates on a slightly different mechanism. With digital payments taking up to a 65% share in the country, German shoppers prefer to use PayPal, Apple Pay, and Google Pay rather than bank cards. Meanwhile, Girocard, Germany’s most popular debit card, controls about 88% of card transactions in physical retail stores. Additionally, invoicing is a staple practice in the country.
For merchants, this means localisation is essential for business success. A checkout designed around different digital and card payments in the country will tap into the country’s retail market worth roughly €328.6 billion.
Many people misunderstand the Netherlands as a “card-enabled” European market. In reality, the infrastructure of its e-commerce economy operates on direct bank transfers. Consumers in the Netherlands prefer to complete transactions directly through their banks.
While the country’s dominant system, iDEAL, continues to process up to 70% of all online transactions, its transition into Wero reflects the wider use of European bank-based payments. To reduce checkout friction and improve payment success rates, merchants should avoid relying exclusively on card networks and be flexible with newer payment methods.
Countries in Southeast Asia are carving a different path from cash or card to mobile-first ecosystems. In fact, a recent study revealed that, in most jurisdictions here, less than 50% of the population has an account with a formal financial institution. Instead, mobile wallets are the go-to for most consumers here. The digital payments market here was worth $1.41 trillion in gross transaction value in 2025 and is projected to grow to $2.4-$2.6 trillion by 2030.
Additionally, the region does not rely on a single payment market. Instead, each country in the region has its own dominant payment system, which includes DANA in Indonesia, Touch ’n Go in Malaysia, GCash in the Philippines and PromptPay in Thailand.
The consequences of neglecting international payment solutions that offer payment localisation can be brutal for an expanding corporation. Attempting to bypass and run global transactions through a unified bank account can result in three layers:
When buyers in Indonesia attempt to make a purchase using the mobile systems built into their infrastructure but encounter a Western bank account, they abandon those purchases.
Global merchants often invest heavily in advertising and landing pages to drive traffic to their online businesses. That is only half the battle; the other half is making sales. If the conversion collapses at payment due to an unfamiliar payment method, all that marketing spend goes to waste.
When merchants process international transactions across multiple countries, foreign exchange spreads and interchange fees may reduce profit margins at scale. They may seem manageable individually. When scaled over time, however, they may significantly dampen the business’s profit margins.
International businesses cannot afford to view localised payment frameworks in their international payment solutions as just an optimisation tactic. Their payment strategy has the potential to transform how shoppers on the ground view and complete transactions with a merchant.
A transaction that appears foreign can suddenly become familiar and trustworthy when local payment rails are provided. The impact is consistent across markets, with payment localisation completely transforming cross-border checkouts into highly trusted domestic experiences for users.
Industry research has consistently shown that payment localisation improves payment approval rates, reduces checkout abandonment, and improves conversion rates. According to a 2026 industry study, integrating domestic infrastructure bridges the cross-border gap where 72% of merchants have higher rates of failed payments compared to domestic transactions.
What happens when merchants implement payment localisation across dozens of markets without an organised orchestration layer? The result is a collection of fragmented infrastructure.
Fragmented infrastructure is a major challenge in Southeast Asia because each country adds its own systems, rules, and integrations. Adopting this at scale without the proper abstraction can quickly become unmanageable.
With the use of modern international payment solutions, true structural localisation adopts a unified gateway that functions as an intelligent payment routing layer. This routing layer will assess all customer metadata, which includes their IP address and device fingerprint, to automatically present high-converting payment instruments.
This allows merchants to scale their businesses without needing their engineers to rebuild their payment stack every time they encounter a new market.
For an expanding international brand, international payment solutions like Antom consolidate various local payment options under a single hood so they can smoothly scale at will. Antom’s unified global payment solution connects merchants to more than 300 local payment methods across over 200 markets and 140 currencies. Through a single integration, businesses can leverage the domestic supply of global consumer payment demand.
Instead of building separate systems for Brazil, Germany, or Indonesia, merchants can now support:
instalment-based payments in Brazil
bank transfer in the Netherlands
mobile wallets in Indonesia, all from a single dashboard
On top of its scalable payment infrastructure, Antom also adds risk control systems that assist internal teams in mitigating fraud exposure and protecting transaction integrity across all target markets.
Global expansion transcends meeting international customers where they are financially. It requires an in-depth understanding of the local financial language. Then, merchants can effectively integrate unified, scalable international payment solutions to drive their global expansion strategy and eliminate cart checkout abandonment. By aligning business goals with payment localisation, international businesses can turn cross-border payments into predictable revenue growth.
What should businesses look for in international payment solutions?
Beyond payment approval and conversion rates, merchants should evaluate fraud detection tools to protect the reputation and integrity of their businesses. Then, businesses should also look into scalable payment options to avoid friction during further expansion.
How many local payment methods should international merchants support?
Businesses do not need to support all the available payment methods. Doing this may be time-consuming and strain the payment infrastructure. Instead, merchants should prioritise extensive research into the dominant payment options within each target market.
