摘要:Fast progress of information-communication technology, distribution of computer networks and wider usage of Internet are basis for the new industrial revolution. Therefore, e-commerce presents new possibility of gathering competitive advantages on the world market, especially for small and medium companies. In order to determine the current stage of electronic readiness and electronic intensity of using the e-commerce in small and medium companies in Croatia, there was a research carried through micro, small and medium companies on national level. Although the acceptance of Internet technologies and implementation of e-commerce ensures to small and medium companies to compete on the world market with large companies and to have efective infuence on their growth and development, the research showed that Croatian micro, small and medium companies, despite of their high level of electronic readiness and implementation of modern information-communication technologies, are not favorable in their usage in everyday business. It is necessary to figure out the universal model to remove barriers for implementation and acceptance of e-commerce.
