Londonderry, New Hampshire is an excellent place to launch a amazon sellers business. With a population of 26K and ~2K businesses, Londonderry offers a robust market. Amazon sellers face unique risks including product liability lawsuits from defective items, intellectual property infringement claims, and account suspensions. An LLC separates your personal finances from your e-commerce business, and Amazon itself recommends sellers operate as a registered business entity rather than as sole proprietors.
