International Payment Processing: Accepting Payments from Global Customers

Accepting payments from customers in other countries involves more than just processing the transaction — it means offering local payment methods, managing currency conversion, understanding cross-border fees, and ensuring your payment infrastructure reaches your customers’ preferred banks. This guide covers everything WooCommerce merchants need to know to accept international payments effectively.

1. The Three Costs of International Payments

Every international transaction has three potential cost layers beyond standard domestic processing:

• Cross-border assessment fee — charged by the card network when the cardholder’s bank is in a different country from the merchant. Visa: 0.40%; Mastercard: 0.60%
• Currency conversion (FX) fee — if the transaction is processed in a different currency from your settlement currency, a conversion fee applies. Typically 1–3%, either charged by the processor or included in the conversion spread
• International acquiring fee — some processors charge a premium for transactions from certain regions, particularly emerging markets

Total additional cost for international transactions: typically 1–3% above domestic rates.

2. Local Payment Methods by Region

Visa and Mastercard aren’t the dominant payment methods in every country. If you’re selling to customers in these regions, offering local payment methods dramatically improves conversion:

ConvesioPay through Adyen supports 100+ local payment methods globally, making it possible to offer the right payment method for each customer’s region without separate integrations.

3. Multi-Currency Pricing Strategy

There are two approaches to currency for international customers:

Dynamic Currency Conversion (DCC)

The customer sees the price in your store’s base currency, and their bank or card processor converts it when they pay. Simple to implement (nothing changes on your end) but the customer bears the FX risk and your bank’s conversion rate is usually worse than the interbank rate. Many customers abandon checkout when they see an unexpectedly large DCC conversion.

Multi-Currency Pricing

You display prices in the customer’s local currency and accept payment in that currency. Requires a currency switcher plugin (WooCommerce has several), geolocation-based currency detection, and a payment gateway that supports multi-currency settlement. ConvesioPay via Adyen supports settling in 30+ currencies, which means you can receive funds in EUR, GBP, CAD, and others without converting back to USD.

Multi-currency pricing reduces cart abandonment from international customers and increases trust — seeing a price in their own currency is less confusing than seeing conversion applied at checkout.

4. EU Merchants: SCA and PSD2

If you sell to customers in the EU or UK, your checkout must support Strong Customer Authentication (SCA) under PSD2. This requires additional authentication for most card payments — either a frictionless flow (no customer action needed) or a challenge flow (OTP or biometric).

• SCA applies when both the merchant’s and cardholder’s banks are in the EEA/UK
• 3D Secure 2 (3DS2) is the primary implementation method
• Certain exemptions apply: low-value transactions (under €30), low-risk transactions based on fraud rates, trusted merchant listings, and MIT (merchant-initiated) recurring transactions
• Non-SCA-compliant checkouts get declined for EU customers

ConvesioPay’s Adyen integration handles 3DS2 automatically, applying the appropriate authentication flow based on transaction risk and applicable exemptions.

5. Settlement Currencies and FX Management

Your payment processor settles funds to your bank account. With multi-currency support, you can:

• Collect EUR from EU customers and settle in EUR to a EUR bank account — avoiding conversion costs entirely
• Collect GBP from UK customers and settle in GBP
• Convert at the point of payout rather than at the point of transaction — sometimes more favorable rates

Without multi-currency settlement, every international transaction converts to your home currency at your processor’s FX rate (typically 1–2% above interbank). For high-volume international sellers, settling in local currencies and converting only when needed can save meaningful FX costs.

6. Cross-Border Tax Considerations

International selling introduces tax complexity that affects your payment setup:

• EU VAT (OSS) — if you sell digital goods or services to EU consumers over €10,000/year, you must register for EU VAT under the One Stop Shop (OSS) scheme and collect the correct VAT rate for each customer’s country
• UK VAT — separate from EU post-Brexit; similar thresholds and registration requirements
• Sales tax (US) — sales tax nexus rules vary by state; high-volume sellers may have nexus in multiple states
• GST (Australia, New Zealand, Canada) — registration requirements for foreign merchants vary by country and threshold

WooCommerce Tax + a tax automation plugin (TaxJar, Avalara, or similar) handles multi-jurisdictional tax calculation at checkout. ConvesioPay’s checkout integrates with WooCommerce’s tax system natively.
