Getting paid can be harder too. I use Paypal to accept subscription payments for my website, and it works for places like Europe and Australia. But if I wanted to expand to South America, it wouldn't take Colombian Pesos, or a variety of other non-western currencies (last I checked).
If you don't use Paypal, you'd have to set up a merchant account, which may or may not be as restrictive. You'd also might have to pay currency conversion fees or other international business fees for the privilege. Laws in some countries might even require you to establish a merchant account with a local bank, which could be difficult, if not impossible, for a small startup.
This might be easier to do for a larger company, but for a one-man startup like mine the 'getting paid' consideration alone would be productivity suicide for me.
