In today's world, with the rapid development of technology, web commerce is becoming increasingly significant, representing the process of buying and selling products or services over the internet. Through planned research, the aim is to determine the prevalence of web usage for shopping among the residents of the Osijek-Baranja County. When it comes to web commerce, the domestic market will be considered to include all online stores primarily intended for the citizens of the Republic of Croatia. The first part of the paper explains the concept and development of web commerce as an appropriate introduction to the research. By using questionnaires and analyzing available data from secondary and tertiary sources, the research will reveal the preferences and behavior of consumers in the Osijek-Baranja County regarding web commerce. Demographic characteristics of respondents, such as gender, age, education, and income, will be identified. The questionnaire will also examine the frequency of internet use for shopping, the types of products and services most frequently purchased through certain web platforms, motivations and obstacles for online shopping, primarily in the domestic market, as well as other issues correlated with the research objectives. The questionnaire was conducted on 320 respondents from the targeted region. A survey was carried out via Google Forms, which collected all the data provided by the respondents. For a better insight into the results, responses were filtered by age, gender, education, and other characteristics, which will later be compared with certain responses for the purpose of statistical analysis. This research will certainly provide an insight into the current state and potential growth of online commerce in the region, and it is expected that the research results will provide valuable and useful insights for local entrepreneurs and merchants. The results of the research will likely open new research questions, which will serve as an impetus for future research and development projects in the field of online commerce.
