When starting their own business, entrepreneurs are preoccupied with numerous questions, and one of the fundamental ones concerns the justification of the realization of a business idea. In order to determine whether a business idea can be turned into a successful business venture, it is necessary to conduct market research and create appropriate economic and financial analyzes and a business plan. In this regard, this final paper deals with the analysis of the justification of the realization of the business idea of providing IT services (sales, servicing and maintenance of IT equipment and programs) with the application of an innovative mobile business concept, i.e. providing services in the field using vans as mobile work units. The conducted analyzes prove the justification of the realization of the business idea. The newly founded company will achieve a comparative advantage at the very beginning of the business thanks to the innovative concept of service provision. This will also contribute to the transformation of shortcomings observed in the competition into opportunities for positioning on the market and business development, for example by combining sales and servicing services, adjusting working hours to the needs of users and effective communication through applications on official websites. The strategic analyzes carried out indicate favorable business circumstances with the assumption of quality management of defined risks. Economic and financial analysis and projections of financial reports confirm rational cost planning, stable and liquid operations that enable regular settlement of assumed obligations and a relatively short investment return period. The continuous realization of profit and its investment in business will ensure the prerequisites for further growth and development. Although it cannot guarantee the success of a business idea, a business plan will certainly contribute to a more successful and less risky business. To ensure the continuity of success, it is necessary to continue to analyze the circumstances that can affect the business, to recognize new business opportunities and turn them into new business ideas.
