One of the essential preconditions for the functioning of any business system is the achievement of and maintaining liquidity, which is a necessary assumption for achieving solvency. Liquidity by definition is the property of the asset, apropos its components, to be taken with as little risk as possible without loss of value and in the shortest possible period converted to cash. The name "liquidity" is often used incorrectly to indicate the solvency of a business system, apropos, to marking the ability of the business system to settle obligations due to its date. The goal of this work is to define liquidity, and explain in more detail ways in which liquidity is expressed and the methods to which liquidity is put into practice , on the example of Čistoća, to conduct a management analysis in liquid assets. In doing so, particular attention will be paid to the ranking of assets considering on liquidity, as well as on the correlation between liquidity ratios and indebtedness, respectively profitability. Based on the conducted insight into the operations of the company Čistoća, it can be stated that adjusting available liquid assets to maturing liabilities may not always be required implying additional borrowing and is already much more acceptable if it can be made managing existing resources.
