The authors aim to clarify the content of the concept of "budgeting" and highlight its main methods that can be used by enterprises in the context of a pandemic and isolation. The authors believe that in order to stabilize the financial condition of an enterprise in the conditions of post-isolation, it is necessary to find a reasonable balance regarding the level of budget detail and to understand that the budget is a tool and it should perform, among many functions, primarily coordination and controlling tasks in modern crisis conditions.
