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. Lewiston is home to ~3K businesses and serves a metropolitan population of 33K, making it an active market for amazon sellers. Forming your South Dakota LLC costs $150 and takes 5–10 business days — giving you immediate liability protection and the legal structure to grow your amazon sellers business in Lewiston.
