This document discusses key differences between B2B and B2C e-commerce implementations. B2B implementations typically involve larger orders from a smaller number of customers, a longer decision-making process involving multiple stakeholders, complex pricing strategies, and a focus on building long-term relationships through recurring orders and additional services. Successful B2B e-commerce requires focusing on features that support complex ordering and catalog needs, integrating business logic and customer needs, and providing tools that help decision-makers easily evaluate and place large orders.
