B2B stands for “business to business.” B2B eCommerce refers to online transactions between two businesses like manufacturers, wholesalers, and retailers. B2B differs from B2C (business to consumer) in terms of purchasing process, brand loyalty, and product knowledge. B2B purchasing is far more complex because it involves more money, risks, and stakeholders. Brand loyalty is very important since businesses tend to seek long-term commitments. Also, B2B customers are usually more educated about the products or services they are buying.
