Abstract: Embodiments provide methods and systems for determination of creditworthiness of a first merchant. The method performed by a server system includes receiving invoice data of the first merchant from a merchant invoice database. The invoice data includes information of past invoices associated with the first merchant. Additionally, the method includes generating a homogeneous graph based, at least in part, on the information of past invoices. Further, the method includes determining a feature representation of the first merchant based on data features associated with the first merchant in the homogenous graph. Furthermore, the method includes calculating a credit risk score for the first merchant based on the credit risk score model.
