Accounting is defined as the skill of recording business events. Accounting defines an information system that represents a condition for the company's operations and has the task of preparing financial statements that contain accounting information on the basis of which certain decisions are made. The basic characteristics of information are accuracy, coverage and precision. Information is simply an indispensable business resource and as such has its own value, and for information to be truly valuable it must serve as a guideline in making business decisions, that is, it must be relevant and significantly influence the outcome of the decision. Managing a business without an adequate information base is unthinkable in today's business conditions when information is a prerequisite for success at every level, and when knowledge and information are a particularly powerful and necessary resource without which there is no desired progress. The business plan of the company is the basic management report of the company, which is defined by the main management, and is prepared in the management accounting of the company. The integral parts of management accounting are planning and control, and accounting records and financial reporting is the primary source of data used in planning, control and analysis. In order to ensure the good functioning of data management, the accounting information of the system should be reliable above all. The most important form of control is the audit and analysis of financial statements. The quality of financial reports implies their usefulness in the business decision-making process. As the process of business decision-making begins with the phase of collecting relevant information, it is clear that low-quality information will most often ultimately lead to the wrong decision.
