Accounting principles are the rules and guidelines that help financial professionals to identify, assess, classify and present information. Apparently, accounting principles are theoretical rules, but some investigations show that behind these general rules are hidden fundamental problems concerning the current accounting organization and financial reporting. Also, these are very general rules that can be applied in different ways, that initiate more accounting treatments. Furthermore, some authors consider that these principles are too conservative, and should be completely reconsidered. Although the foreign specialty literature suggests numerous principles classifications, during this research we will analyze forward the terms that are valued as accounting principles, their evolution in the Republic of Moldova, as well as their influence on young accounting and financial reporting. In this research was used the comparison method, analysis, deduction and historic method. The findings of this investigation will contribute to the development of accounting principles perception and applicability, not only by those who study and research the accounting sector, but also by those who implement bookkeeping in all their stages of work: drawing up accounting policies, identifying, assessing and registering economic transactions and drawing up entity’s financial statements.
