Manual checking of private and business accounts during credit approval processes consumes time and resources and is also prone to errors. With KreditCheck it is possible to significantly speed up credit decision processes and comprehensive analyses of the customer's accounts. Expenses and revenues are automatically recognized, categorized, and evaluated. The basis for this is a defined rule set, which can be adapted as required. The results are output either in JSON format or in a clear PDF. The credit check provides the bank advisor with well-founded information on the customer's creditworthiness, on which he can base his credit decision.
