The business models are changing very fast. The traditional way of business was an offline business that is now shifted to online. People love to do online sell and purchase. It is beneficial for both the buyer and the seller. The most knowingly business models are B2B and B2C. These two are the most popular ones and B2C is the most commonly used one. In our day to day lives, we used to do sell and purchase through this model. But the business models are changing and there are so many other business models available where a consumer can do business with other businesses without any investment. Consumers also can sell purchases with each other. So this is the way how business models are changing.
