This study aims to analyze the process of preparing a proposal for the event "Re-Grand Launching BMW Performance Motors Indonesia" by PT Aldena Ganthari Kreatf. The purpose of this study is to understand the steps in the preparation of the proposal as well as the challenges faced and solutions implemented during the process. The research methods used are observation, secondary data collection through documentation, and interviews and analysis methods carried out are qualitative descriptive. The results of the study show that 1) In the process of preparing the BMW PMI Re-Grand Launching proposal, there are several discrepancies with the pitching process theory in Aryanti & Rudatin (2022). 2) The challenges faced in the proposal preparation process are the short time in processing and changes in the client's wishes that have the potential to change the concept. In facing these challenges, Event Organizers (EOs) must create vendor-related databases and create effective schedules to achieve short time targets and always maintain communication with clients.
