In the modern business environment, communication plays a crucial role in establishing and maintaining successful business relationships. It is not just the transmission of information but also a complex process involving the exchange of messages, ideas, and attitudes among different stakeholders, in this case, between the real estate agency and its clients. Successful communication with clients is a key component in creating customer satisfaction and building long-term business relationships. This final paper thoroughly analyzes the communication between the real estate agency Stella&Mar and its clients. Through a theoretical overview of communication concepts, modern communication technologies, and business and sales communication, the research was conducted to gain a deeper understanding of customer satisfaction with communication and their experiences with the real estate agency. Empirical research was conducted on a sample of 53 clients of the selected real estate agency. Through a questionnaire survey, clients evaluated various aspects of communication with the agency, including response time, clarity of information, friendliness of staff, and agent availability. The research results showed that the majority of clients expressed satisfaction with the communication with the real estate agency and would gladly recommend it to their acquaintances. These results emphasize the importance of proper communication management in the business context, especially in the real estate industry where trust and transparency are crucial. Real estate agencies that succeed in establishing efficient and friendly communication with clients have a greater chance of success and building a positive reputation in the market. Additionally, this research provides valuable insights and guidelines for improving communication processes and practices within real estate agencies to ensure continuous customer satisfaction and long-term business success.
