The U.S. and Mexico have cultivated a dynamic business environment that encourages innovation, collaboration and mutual prosperity for small businesses with partners, employees, and customers across the border. Part of the competitive advantage for both U.S. and Mexican entrepreneurs is the geographical proximity; however, there are also challenges related to cross-border product shipment, delivery, payment, and knowing the key legislation related to taxes, customs, etc. Entrepreneurs with cross-border ties must be able to have effective international communication, and when this comes to the smallest businesses with shoestring budgets, international calling costs (and cost-savings) can really matter.
