Expanding into new markets means solving payments in every country you operate. Global business payments are far more complex than domestic transactions — different currencies, local payment methods, regulatory requirements, and settlement timelines all add friction. For platforms and businesses processing international payments, the difference between a well-architected payment stack and a bolted-together one is measured in approval rates, revenue, and customer experience.
This guide breaks down everything you need to know about global payment processing: the challenges, the strategies, and the infrastructure decisions that determine whether your international expansion succeeds or stalls.
What Are Global Payments?
Global payments refer to any financial transaction that crosses national borders — whether that means a customer in Germany paying a merchant in the US, or a platform settling funds to suppliers across Southeast Asia. The term encompasses both the movement of money and the infrastructure that makes it possible: payment gateways, acquirers, card networks, local payment schemes, and foreign exchange providers.
For online businesses, global payments typically involve accepting cards and alternative payment methods from customers worldwide and settling in your preferred currency. For offline businesses — think retail chains, hospitality, or field services — global payments also include in-person terminals that handle multi-currency transactions and local card schemes.
The global payments market is growing rapidly, driven by cross-border e-commerce, platform business models, and the digitalisation of B2B payments. But growth brings complexity. Every new market you enter introduces new payment preferences, regulatory frameworks, and operational requirements.
Challenges of International Payment Processing
Processing payments across borders introduces several layers of complexity that domestic-only businesses never encounter:
Foreign exchange (FX) costs: Every cross-border transaction involves currency conversion, and the spread between wholesale and retail FX rates can eat 1-3% of transaction value. Many PSPs add their own markup on top, making FX one of the largest hidden costs in international payments.
Local payment method fragmentation: Cards dominate in the US and UK, but iDEAL is essential in the Netherlands, Boleto in Brazil, UPI in India, and GrabPay in Southeast Asia. Failing to offer preferred local methods means losing customers at checkout.
Regulatory and compliance variation: PSD2 and SCA in Europe, RBI guidelines in India, LGPD in Brazil — each market has its own rules governing how payments are processed, how data is stored, and what authentication is required.
Settlement timelines: Settlement periods vary by country and acquirer, from T+1 in some European markets to T+7 or longer in parts of Latin America and Africa. This affects cash flow and treasury planning.
Declined transactions: Cross-border transactions are declined at significantly higher rates than domestic ones. Issuing banks are more cautious about approving transactions from foreign acquirers, and mismatched BIN data triggers fraud filters.
These challenges compound as you scale. A business processing in three countries might manage with a single PSP, but operating across 20+ markets demands a more sophisticated approach.
Local Acquiring vs Cross-Border Processing
One of the most important architectural decisions in global payments is whether to process transactions through local acquirers in each market or route everything through a single cross-border acquirer.
Cross-border processing is the simpler option. You connect to one PSP — say Stripe or Adyen — and they process all your transactions regardless of where the customer is. The downside is that cross-border interchange fees are higher, approval rates are lower, and customers may see unfamiliar merchant descriptors on their statements.
Local acquiring means establishing acquiring relationships in each market so that transactions are processed domestically. A German customer's card transaction is acquired by a German acquirer, classified as a domestic transaction, and benefits from lower interchange rates and higher approval rates. For a deeper breakdown of how this works and why it matters, see our guide on local acquiring for international payment collection.
The trade-off is operational complexity. Local acquiring requires either setting up entities in each country or working with PSPs that have local acquiring licences across your target markets. The payoff is significant though: businesses that move from cross-border to local acquiring typically see approval rate improvements of 5-15% and interchange savings of 0.5-1.5%.
Popular Global Payment Methods by Region
Understanding regional payment preferences is critical for any international payment solution. What works in one market will fail in another. Here is a breakdown of dominant methods by region:
North America: Credit and debit cards (Visa, Mastercard, Amex) dominate, with digital wallets like Apple Pay and Google Pay growing rapidly. ACH bank transfers are common for B2B and recurring payments.
Europe: Cards remain strong, but SEPA Direct Debit is widely used for subscriptions and B2B. Local bank transfer methods are essential — iDEAL in the Netherlands (60%+ of e-commerce), Bancontact in Belgium, Przelewy24 in Poland, and Klarna/buy-now-pay-later across the Nordics and Germany.
Asia-Pacific: The most diverse region. UPI handles billions of transactions monthly in India. Alipay and WeChat Pay dominate China. GrabPay and ShopeePay are growing in Southeast Asia. Japan relies heavily on convenience store payments (konbini) alongside cards. South Korea uses local card networks and bank transfers.
Latin America: Boleto Bancario and Pix in Brazil, OXXO vouchers in Mexico, and local card instalments (cuotas) across the region. Cash-based voucher payments remain significant in markets with lower banking penetration.
Middle East & Africa: M-Pesa and mobile money dominate in East Africa. Mada is the national payment scheme in Saudi Arabia. Cash on delivery remains a significant share of e-commerce in many markets, alongside growing adoption of digital wallets.
A robust global payment gateway needs to support the methods that matter in your target markets — not just Visa and Mastercard everywhere.
How to Choose a Global Payment Gateway
Selecting the right global payment gateway is one of the highest-leverage decisions for an internationally expanding business. Here are the factors that matter most:
Geographic coverage: Does the gateway support local acquiring in your target markets, or only cross-border processing? Check not just which countries are listed, but whether they have direct acquiring relationships or are routing through intermediaries.
Payment method breadth: Can it handle the local methods you need? Some gateways are strong on cards but weak on bank transfers, wallets, or voucher-based methods.
Multi-currency settlement: Can you settle in local currencies, or does everything convert to your base currency? Local settlement reduces FX exposure and can improve reconciliation.
Pricing transparency: Look beyond the headline transaction fee. What are the FX markups, cross-border surcharges, chargeback fees, and minimum monthly commitments per market?
Compliance and data residency: Can the gateway meet data localisation requirements in markets like India, Russia, or Indonesia where payment data must be stored in-country?
API quality and integration effort: How much engineering time does integration require? Is the API well-documented? Can you test in sandbox across all supported markets?
No single gateway excels everywhere. That is why the most sophisticated global businesses are moving toward a multi-PSP approach.
Multi-PSP Strategy for Global Payments
Relying on a single PSP for global payments is a risk and a limitation. No one provider has the best acquiring relationships, the lowest FX rates, and the broadest local method coverage in every market. A multi-PSP strategy lets you route transactions to the optimal provider for each market, payment method, and use case.
For example, you might use one PSP for European card acquiring where they have strong local relationships, a different provider for Southeast Asian wallets, and a third for Latin American bank transfers and voucher payments. For a detailed comparison of the single-provider vs multi-provider approach, see our guide on PSP-neutral vs single-PSP strategy.
The challenge with multi-PSP is orchestration. You need a layer that sits above your PSPs and handles routing logic, failover, reconciliation, and reporting across providers. This is where a payment layer or embedded payments infrastructure becomes valuable — particularly for platforms that need to manage payments on behalf of their customers across multiple geographies.
Benefits of a well-executed multi-PSP strategy include:
Higher approval rates through intelligent routing to the best-performing acquirer per market
Lower processing costs by leveraging competitive pricing across providers
Reduced vendor lock-in and negotiating leverage when contracts renew
Built-in redundancy — if one provider goes down, traffic fails over automatically
Faster market entry by connecting to whichever PSP already has coverage in a new geography
Online vs Offline Global Payment Considerations
Global payments work differently depending on whether you are processing online (card-not-present) or offline (card-present) transactions.
For online businesses, the primary concerns are checkout conversion, local payment method availability, and 3D Secure authentication flows that vary by market. A checkout page that works well in the US — simple card form, no authentication step — will lose customers in markets where bank redirects, two-factor authentication, or instalment selection are expected.
For offline businesses, the challenges are different: terminal hardware and certification vary by country, contactless limits differ, local card scheme support (Cartes Bancaires in France, girocard in Germany) requires specific terminal configurations, and tax receipt requirements add complexity. Multi-country POS rollouts require managing different acquiring contracts, terminal fleets, and settlement accounts per market.
Businesses that operate across both channels — known as unified commerce — face the challenge of reconciling online and offline transaction data, managing a consistent customer experience, and maintaining a single view of payment operations across markets and channels.
Building Global Payment Infrastructure for Platforms
For platforms — SaaS companies, marketplaces, and software businesses that facilitate payments for their customers — global payments add another dimension of complexity. You are not just processing your own transactions; you are building payment infrastructure that your customers rely on across markets.
This is where the concept of a payment layer becomes critical. Rather than hard-wiring a single PSP into your platform, a payment layer abstracts the complexity of multiple providers, currencies, and local methods behind a unified API. Your customers get a seamless payment experience regardless of which country they operate in, and you can add new markets by connecting new PSPs without re-architecting your integration.
Shuttle Global helps platforms solve exactly this problem. Our infrastructure connects to multiple PSPs across regions, handles the orchestration and routing logic, and lets platforms offer global payment capabilities — including embedded payments and voice checkout — without building and maintaining the plumbing themselves.

Frequently Asked Questions
What is the difference between a global payment gateway and a local acquirer?
A global payment gateway is the technology layer that connects your checkout to one or more acquirers and processes transactions across markets. A local acquirer is the financial institution that actually settles the transaction with the card network in a specific country. Many global gateways offer their own acquiring in some markets and partner with local acquirers in others. The distinction matters because local acquiring delivers better approval rates and lower interchange fees than cross-border acquiring.
How can I reduce FX costs on international payments?
Three strategies help reduce FX costs. First, settle in local currencies where possible to avoid double conversion. Second, use local acquiring so that transactions are processed domestically and avoid cross-border interchange. Third, compare FX markups across PSPs — the spread above mid-market rates varies significantly between providers and is often negotiable at scale.
Do I need a separate PSP for each country?
Not necessarily. Large PSPs like Stripe and Adyen offer local acquiring in dozens of markets through a single integration. However, they may not have the best rates or coverage in every market. A multi-PSP approach — using a payment layer to route to the best provider per market — gives you the benefits of local acquiring without the complexity of managing many separate integrations directly.
What approval rate improvement should I expect from local acquiring?
Businesses typically see a 5-15% improvement in approval rates when switching from cross-border to local acquiring. The exact improvement depends on the market, card mix, and transaction profile. Markets with strong issuer preferences for domestic transactions — such as Brazil, India, and parts of Southeast Asia — tend to show the largest improvements.
How do platforms handle global payments for their customers?
Platforms typically start by integrating a single PSP and passing through its capabilities to customers. As they scale internationally, they move toward a payment layer approach — an abstraction that sits above multiple PSPs and routes transactions to the optimal provider per market. This lets platforms offer embedded payments with global coverage without requiring their customers to manage PSP relationships directly.
