eBay

eBay combines auction-style and fixed-price selling in one platform, letting sellers reach millions of potential buyers globally. The Seller Hub provides inventory management, shipping label printing, and automated relisting to reduce repetitive work. eBay handles payments and dispute resolution, letting sellers focus on sourcing and customer service.

Best suited for resellers, collectors, and businesses offloading excess inventory who value eBay's established buyer base. Compared to niche marketplaces, eBay works across most product categories and offers a lower barrier to entry, though competition is intense and fees apply to every sale.
