Regular online shopping (B2C) targets individual consumers, while B2B e-commerce involves business-to-business transactions. This difference creates several practical distinctions: B2B purchases typically involve larger order values, more complex specification confirmation, longer procurement cycles, and repeat purchases from the same customer. Because of this, the focus of B2B e-commerce is not just to complete the first order, but to establish a system that allows customers to self-serve for ordering and reordering, reducing the back-and-forth costs of having to inquire from scratch each time. For example, an automotive parts manufacturer selling engine components, fuel pumps, and screws to automotive manufacturers for assembly—not to end consumers—operates on a completely different procurement logic than a general e-commerce business.
