The acronym B2B stands for Business-to-Business, referring to eCommerce transactions between businesses rather than between a business and individual consumers (B2C). In B2B transactions, companies sell goods or services to other companies, often involving larger quantities and higher value compared to consumer sales. B2B platforms facilitate these transactions through online portals that allow businesses to manage orders, payments, and deliveries, streamlining the purchasing process and enhancing efficiency in supply chain management.
