First of all, the level of individual economic indicators that capture aspects of liquidity, and profitability was investigated. With the help of bankruptcy models that predict the company's future financial difficulties, we will try to discover the causes of bankruptcy. The first part focuses on the definition of basic concepts and procedures in the prediction of the financial health of businesses and individual authors and creators of bankruptcy models in Poland. Subsequently, the methodology by which we proceeded in assessing the economic recovery of Polish companies was determined. Individual companies as stable or unstable in terms of their financial health were identified. In the case of instability, we have further considered what could have been the cause of this instability.
