How do I accept international payments?

Most major processors (Stripe, PayPal, Adyen) support multi-currency checkout that converts automatically. Key considerations: cross-border fees add 1-2% per transaction, you'll need to handle VAT/GST for EU/AU customers, and some payment methods are region-specific (iDEAL in Netherlands, PIX in Brazil). Stripe supports 135+ currencies and 40+ local payment methods.
