When I created an online business in 2011, one of the most serious problems I faced was being able to accept credit card and Paypal payments on my site. It took me a couple of days searching for the best online payment processor for my country.
Most of what I found simply had my country excluded from their lists and this was becoming so frustrating. Paypal which is obviously the most recommended online payment gateway, at the moment of writing this post does not seem to see business in most 3rd world countries.
As my search went on, I came across 2checkout and that drove me into an aha moment.
