I want to do Amazon FBA but analyze: how much money do I need to start? Map FBA requirements: product sourcing, inventory, Amazon fees, advertising, shipping. Calculate: realistic starting capital for viable FBA business. Show me the FBA investment: need this much to start, this much to maintain. Give me the capital reality: FBA isn't "no money" business, requires real investment. Include: what FBA actually costs to start, whether I have enough capital, and if I should save more before starting.
