To build internationally, you must have several important things locked down. First, you must have a system in place that takes care of all international customs challanges. Second, you must have a distribution system in place to minimize each countries shipping costs. And finally, you must have an international currency exchange set up so that you and your international netwok can be paid consistently and properly.

You must be focused on building your international network resulting in solid residual international income. Can you imagine receiving weekly income from multiple countries?
