Integration of a Supply Management Platform into a CRM System for Car Washes: A Data-Driven Approach to Improving Purchasing Processes

This bachelor’s thesis focuses on the design of an integration solution connecting a Customer Relationship Management system with a Supply Chain Management platform in the context of small and medium-sized car wash businesses. The main goal is to automate the inventory ordering process using predictive analytics, which takes into account seasonal fluctuations, historical data, and weather conditions. The thesis proposes an integration architecture, develops a system prototype, and performs a simulation demonstrating a significant reduction in administrative workload and improved inventory management efficiency. The results confirm that implementing an intelligent purchasing planning tool can be a valuable step towards digital transformation in the service sector.
