I assume you are talking in the form of ACH or direct debit payments and not credit card payments. Unfortunately I am not aware of any service outside of PayPal where you can transfer via ACH internationally. The two promising upcoming options Dwolla and Balanced both only current support US bank accounts for ACH payments. With credit cards there are numerous options (i.e. Stripe, Braintree, Balanced, Authorize.net, etc...).
