The sales process is usually simpler and more focused on generating immediate sales.

B2B, or "business-to-business," e-commerce refers to the sale of goods or services between businesses.

B2B e-commerce companies typically have a smaller number of customers, but those customers tend to be other businesses that may buy in large quantities.
