Today, information technologies are becoming increasingly important in everyday business and have become one of the most important factors in the development of entrepreneurship. The long history of entrepreneurship is known even before the development of any information technology, but it is also obvious that after the introduction of information technology in the business of entrepreneurship, a better way of doing business has been achieved. Due to the importance and changes to which entrepreneurship is exposed, business has always been the subject of many studies, and today a significant place in research is occupied by the issue of the impact of information technology on small, medium and large enterprises. With the development of information technologies, entrepreneurs have better access to data with which (if they use them well) they can significantly facilitate their business, but also make more money. With the development of the Internet, the competition has become much greater because now all entrepreneurs can find out what interests them at any time, while a few years ago they had to wait a few days for the desired information. Today, there is an increasing number of new "e-companies" in entrepreneurship, because with the help of the Internet it is possible to order and pay for a product without coming to a physical point of sale. Business innovations are continuous due to the continuous introduction of new technologies, business models and communication approaches. All companies that understand the importance of e-commerce today must have a website so that users can find them more easily. The Internet has also brought about a change in the application of marketing, as it is no longer enough to just start a business, but it needs to be well advertised “online” to make people realize that something is not happening in their environment. The development and use of information technology greatly help to achieve the competitive advantages of companies, simplify their business process and improve the skills of their employees.
