International and Multi-Currency Payments

Displaying prices in the buyer’s local currency increases conversion measurably. According to Stripe data, presenting the price in local currency can improve payment acceptance rates by up to 12% compared to charging in a foreign currency.

There are two main approaches: dynamic pricing (calculated in real time by applying the exchange rate) and fixed pricing per market (manually defined for each currency). Fixed pricing offers more margin control but requires active management. Dynamic pricing is simpler to operate but exposes the merchant to exchange rate fluctuations.

Currency conversion (FX) is a significant cost in international payments. Payment gateways apply a markup over the interbank exchange rate ranging from 1% to 3% depending on the provider and the currencies involved.

Stripe charges a 2% markup on currency conversion. Adyen applies between 1% and 1.5% depending on the currency pair. PayPal can reach 3–4% including the spread. To minimise costs, the optimal strategy is to hold balances in major currencies and settle in the seller’s local currency only when necessary.

Visa and Mastercard cards are not enough to sell globally. In many markets, local payment methods account for the majority of online transactions. Not offering them means losing a significant portion of potential sales.

When a customer in Germany pays by card at a merchant processing from Spain, the transaction is cross-border. This means higher fees (elevated interchange) and lower approval rates (issuers are more cautious with international transactions).

The alternative is local acquiring: processing transactions through an acquirer in the buyer’s country. Adyen and Stripe support local acquiring in multiple markets, which reduces interchange fees and improves approval rates. For key markets with significant volume, local acquiring can save between 0.5% and 1.5% per transaction.

Selling internationally means managing indirect taxes for each jurisdiction. In the EU, VAT is applied based on the buyer’s country (destination principle) for digital services, with rates ranging from 17% (Luxembourg) to 27% (Hungary). In the US, sales tax varies by state, county and city.

The tax complexity leads many merchants to adopt Merchant of Record (MoR) solutions like Paddle, FastSpring or Lemon Squeezy, which act as the legal seller and handle collecting, reporting and remitting the applicable taxes in each country.

Beyond taxes, selling internationally may require compliance with market-specific regulations. Data protection (GDPR in Europe, LGPD in Brazil, CCPA in California), consumer laws, export restrictions and trade sanctions are areas that must be evaluated.

Some jurisdictions require specific licences to process payments or act as a financial intermediary. Payment gateways with their own licences (Stripe, Adyen) cover most of these requirements, but the merchant remains responsible for complying with local sales and consumer protection laws.

Expanding into new markets does not have to be all or nothing. A progressive approach allows you to validate demand before investing in local acquiring, market-specific payment methods and full tax compliance.

Start by accepting cross-border card payments and PayPal. When a market shows traction, add local payment methods and local currency pricing. In the next phase, set up local acquiring and tax compliance. This phased approach reduces risk and optimises investment.
