There are actually multiple types of eCommerce businesses. However, if we need to cut it down to just two, they would be B2C and B2B businesses. B2C (Business to Consumer) is the most common type of business model. You are a business that sells goods or services to consumers, who, in turn, use your products in their everyday life. Companies that consider themselves to follow the B2B (Business to Business) model sell their goods or services primarily to other businesses.
