With BizPayO you can get paid from around the world, but there are some limitations with cross-border payments as follows:

For credit card payments, you can accept international payments from card holders and countries which are not sanctioned by the US. The Office of Foreign Assets Control ("OFAC") administers and enforces sanctions based on US foreign policy and national security goals against targeted foreign countries and regimes, terrorists, international narcotics traffickers.

For ACH/Echeck payments, as long as your customer pays you from a US bank account with a valid routing and account number, you can accept payments without limitation.
