third party selling on amazon is the backbone of the platform’s marketplace model, giving millions of independent sellers access to a global audience. Third-party sellers operate their own businesses, sourcing inventory, managing product listings, and determining pricing. Amazon provides the infrastructure for these sellers to scale quickly via FBA, sponsored ads, and global marketplaces. With proper research and execution, third-party selling can be a lucrative e-commerce opportunity. Sellers must stay informed on policy changes, optimize SEO, and focus on customer experience.
