The eCommerce order processing model refers to the planning, organizing, directing, and controlling of your business operations to make profits. There are many business models, including the B2B, B2C, and D2C models.
B2C model means when processing orders for the customers, while B2B means selling directly to the businesses. While both D2C & B2C models deal directly with customers, the major difference between the two is; in B2C, businesses can sell products of other brands as well, whereas, in D2C, businesses sell their own products, eliminating the scope of middlemen and distributors.
