Purpose of research: grounding of the theoretical statements and working out of the practical recommendations on improving the order of forming and applying accounts as the element of accounting method under conditions of institutional changes and implementation of the information and computer technologies to assist in the effective accounting functioning as an information source for providing efficient management of the business entity's activity. Object of research: accounts as an element of accounting method under conditions of institutional changes and implementation of the information and computer technologies. Subject of research: theoretical and practical issues on improving the order of forming and applying the accounts. Methods of research: historical method, system approach, analysis, synthesis, comparison, specialization, causative-consecutive method, modeling, statistic observation, survey, grouping, graphic method. Scientific novelty of the results obtained lies in the theoretical grounding and practical solution of a number of issues on improving the order of forming and applying accounts for providing the effective functioning of the accounting system as a basis of the efficient corporate management. The basic grounds of scientific novelty lie in the following: for the first time the results as follows have been obtained: the system of principles of developing the working chart of accounts (legitimacy, criteria optimization, uniformity, systematization, rationalization, adaptability, multivalued coding), following of which assists in satisfying the internal and external users' needs, creates the possibilities of forming reliable indexes of accounting reporting, carrying out efficient analysis as well as executing opportune control and detecting the reasons of deviations in the business activity of an enterprise. The issues have been improved as follows: classification of accounts according to the following features: 1) by the economic sense of the accounting objects; 2) by the function and structure; 3) by the relation to the balance. The above stated allows to disclose the interrelation of the classification elements, study their structure as well as demarcate and specify the objects of accounting reflection for increasing the effectiveness of their management; grounding of the cognitive purpose of accounts under conditions of institutional changes in the economy through their application as catalectic models where internal and external objects of company's activity find their reflection (i.e. transaction costs), the usage of which gives the possibility in the simplified and convenient form to extrapolate all the business facts and provide corresponding data in the comprehensible for the user form; classification of the chart of accounts through the theoretical grounding of the suggested kinds (according to the way of determining the financial result; allocation and coding of accounts; features taken as a basis in ranking synthetic accounts; demarcation of accounts for the purposes of preparing external and internal reporting; binding to different forms of reporting), application of which will allow to work out in detail the approaches to the development of the working chart of accounts as well as increase the effectiveness of using the data reflected on accounts for the sake of management; approaches to working out the Chart of accounts for assets, equity, liabilities and business transactions of Ukrainian enterprises and organizations in the part of the suggested content for different management levels and determination of competences of the corresponding authorities.

Implementation extent: research results have been implemented into the practice of the Limited Company "Ukrlytnasinnya", Limited Company "Reklamne Dzherelo", Limited Company "Etikon", Limited Company "Krigerkotloservis".
