The main objectives of this paper are: define the bakruptcy of small and medium enterprises problem and review ralated works to gather knowledge about used methods to predic probability of default an lastly create a binary classification model for bankruptcy of enterprise. Models were built on one of Scandinavian bank‘s behavior and transactions history data. Three classification algorithms (random forest, neural networs, xgboost) were tested using 182 variable. Best model was obtained by using xgboost algorithm with 5 fold cross validation with the result AUC = 0,817, while random forest‘s AUC = 0,763, neural network‘s AUC = 0,69. After investigating most important variables extracted from best performed model there can be made a conclusion that out of 182 variables related with costumers behavior, dutifulness for paying payments for their loans are more important and informative than behavior with money compared with liabilities and income.
