An Amazon Seller is an individual or business that sells products on Amazon’s marketplace. Sellers can operate under different models, such as private label, wholesale, arbitrage, or dropshipping. They are responsible for sourcing products, managing inventory, optimizing listings, handling customer service, and overseeing logistics. Some sellers use Fulfillment by Amazon (FBA), where Amazon manages storage, shipping, and customer support, while others fulfill orders themselves (FBM). Success as an Amazon Seller requires market research, competitive pricing, and effective marketing strategies.
