Marketplace is a website where the products offered come from multiple sellers. The variety of assortment a marketplace offers is exactly what attracts customers – just like a shopping mall does in real-life. Whereas, E-Commerce is a website where a single vendor sells his products/services to multiple customers. As the website belongs to the vendor, only two parties are involved in the sale process – the seller and the buyer.Unlike marketplaces, which make sure their sites are always robust and up-and-running, e-commerce websites need to be set up and maintained by the seller.
