Hi,
As I explained in your email enquiry on our website the plugin is a payment gateway for Australian businesses only.
It will not function for non-Australian businesses at the moment. Like other gateways you need to set up a account to get the credentials required to accept payments. This is a requirement of the Australian banking system to prevent money laundering etc.
If you would like to set up a merchant account then the Merchant Plan Pricing page is the place to start and then here when you are ready to make a Merchant Account Application
We will settle funds to any Australian bank account for the business applicant.
Regards, Peter
