This master thesis develops and applies XGBoost-based predictive analytics to estimate the likelihood of bill rejections from historical billing records. It examines drivers such as project rates, billing office attributes, employee roles, and textual narratives in work descriptions. A predictive tool is built to flag high-risk bills before client submission, combining data preprocessing, feature engineering, and hyperparameter optimization. Results indicate that while narratives matter, project area and billing office are more decisive for acceptance versus rejection, supporting data-driven billing process improvements.","Escuela de Negocios  \nTipo de documento: Tesis de maestría  \nMaster in Management + Analytics  \nPredictive analytics in legal billing: an applied machine learning approach to forecasting bill rejections  \nAutoría: Quevedo, Carlos María  \nAño: 2025  \n¿Cómo citar este trabajo?  \nQuevedo, C.

However, bill rejections or discounts requested by clients can significantly impact the revenue streams of law firms. This thesis presents a practical application of machine learning-the XGBoost algorithm-to forecast the likelihood of bill rejections based on historical billing data. The research explores various factors that contribute to bill rejections, including project rates, billing office attributes, employee roles, and the narratives associated with the work descriptions.  \nThrough the development and deployment of a predictive tool, this thesis provides a datadriven approach to identifying high-risk bills before they are sent to clients. The findings suggest that while narratives are important, other factors such as project area and billing office play a more significant role in determining whether a bill will be accepted or rejected. This work also delves into the preprocessing techniques, feature engineering, and hyperparameter optimization processes that are crucial to the model's success. The implications of these findings are discussed in the context of improving legal billing practices and reducing financial risks for law firms.  \nIndex  \n1.
