Credit scoring models can be useful for merchants to make better decisions, but they must be implemented and managed strategically. Before using credit scoring models, merchants should define their goals and criteria for credit or payment decisions, such as target market, risk appetite, expected return, and customer experience. Additionally, merchants must choose the type and provider of credit scoring models that best suit their needs and objectives. This could include generic, custom, or hybrid models, or a combination of them; working with external or internal providers; or both. Furthermore, merchants should monitor and review their results and performance regularly to ensure they are meeting their goals and criteria. This includes approval rates, default rates, customer feedback, and profitability. They should also compare their results with competitors and industry benchmarks. Finally, based on the results and performance, merchants should update and improve their models and data periodically by adding new data sources, adjusting factors or weights, changing methodologies or algorithms, validating data for accuracy and reliability.
