Loans, performing the functions of a loan, have various forms and help to use the funds received more flexibly. An enterprise can receive a loan in the most convenient form for itself – directly a loan, in the form of a bill of exchange or by issuing bonds.

The role of credit is important, which is able to solve the problem of non-payments and lack of working capital among enterprises, to prepare resources for raising production. However, in the current unstable environment, not only the very fact of lending is important, but also how exactly the loan is issued, its timely and correct accounting.

Under these conditions, the role of the correct accounting of credits and loans in the accounting departments of enterprises has increased. The knowledge of the management of the enterprise of their volumes of their structure depends on the correctness and reliability of accounting for loans and loans, allows you to make the right decisions to change these characteristics, allows you to analyze the profitability of the funds received, etc. Proper accounting will allow in the future to choose the most convenient and profitable type of receipt of additional funds for the enterprise.
