Whether you're expanding internationally or already operating across borders, finding the right international payment gateway can make a world of difference to your customers and vendors—and your bottom line.
This guide explores the top international payment gateways and how to choose the best fit for your business.
What is an international payment gateway?
An international payment gateway processes electronic payments across national borders, enabling businesses to both make and accept payments worldwide. In other words, it acts as an intermediary between your business, the payment method being used (like a credit card or digital wallet), and any financial institutions involved in completing the transaction.
These gateways handle currency conversion, ensure compliance with international banking regulations, and provide security measures to protect sensitive financial data.
What kind of international payment gateway do I need?
1. Retail websites with international shoppers. If you have a retail shopping website and you're looking for a plug-and-play widget to take credit card payments from overseas customers, that's a very specific use of an international payment gateway. Look for one that:
- Covers the countries and currencies you need for your retail operations
- Works with your ecommerce platform
2. Overseas B2B payments. If your intention is to make B2B payments to overseas vendors or take B2B payments from overseas clients, that's a different kind of functionality—and precisely what BILL is designed for:
- Pay vendors with the same automated workflows you use for domestic payments
- Keep domestic and international AP tasks and data in one convenient dashboard
- Sync your AP activity with popular business accounting software and ERPs

How to choose the right international payment gateway
Choosing the right international payment gateway requires careful analysis of your current and near-future needs—including target markets and operational requirements.
If you need to pay overseas vendors and freelancers, BILL provides a B2B payments ecosystem that lets you pay domestically and internationally in the same system, right where you manage your bills and invoices—so you can handle your AP and payments in the same place, no matter where the payment is going.
If you're only looking to take international consumer payments on a retail or digital subscription website, here's a list of things to consider during your selection process.
Factors to consider when selecting an international payment gateway
Geographic coverage and currency support are foundational considerations, as your gateway needs to operate effectively in your target markets while supporting relevant currencies and local payment preferences.
Your payment gateway should offer transparent pricing with cost-effective transaction fees, competitive exchange rates, and no hidden costs that could impact your margins or pricing strategy.
Technical requirements and integration capabilities need careful evaluation to ensure the gateway will work smoothly with your existing systems while providing the API access and documentation you need.
Comparison of different international payment gateway providers
When comparing providers, focus on the key operational aspects that will impact your daily business activities and long-term growth potential.
Settlement periods and payout options vary significantly between consumer credit card payment gateways, affecting your cash flow and financial planning. Look for providers offering terms that align with your business model and cash flow needs.
Technical capabilities and integration options should match your current needs while providing room for growth, including API access, developer tools, and compatibility with your e-commerce platform.
Security and fraud prevention measures in international payment gateways
Security infrastructure is paramount for international payment processing, as cross-border transactions often face higher fraud risks and more complex regulatory requirements.
Your chosen gateway should be as secure as making payments through a bank, with industry-standard 2-step verification and SSL encryption.
Fraud prevention tools should include real-time monitoring and appropriate security measures based on your risk tolerance and market requirements.
Risk management capabilities need to extend beyond basic fraud prevention to include dispute resolution support and tools for managing regional compliance requirements.
