Opening a company
swombat: Surely you can take international credit cards with a Brazilian merchant account? If authorize.net don't allow that, there are many other similar providers which can help.Setting up a merchant account is a major pain in the ass (and slow) even if you are based in the UK... I imagine it'd be even harder if you're not, and really, it's not worth the hassle unless there's really no other way to take CC payments.
