Company Profile PT Sumber Sejahtera.

To fulfill and perfect my research methodology task entitled "Web-Based Online Sales System Design Using the Waterfall Method at Pharmaceutical Distributor PT SUMBER SEHAT SEJAHTERA to Improve Transaction Efficiency and Marketing Reach," I developed a company profile website for the company.

This project implements the Waterfall method to design and build a web-based online sales information system in the form of an integrated Company Profile for PT SUMBER SEHAT SEJAHTERA. The system was developed using Laravel 12 Framework as the core foundation and Filament v5 for efficient admin panel database management. Considering the research object is a pharmaceutical distributor, the system is equipped with a large-scale product catalog management feature optimized using the Intervention Image and Spatie Image Optimizer packages to maintain page loading speed performance. Transaction security and data validation within the system are reinforced with Google reCAPTCHA integration, while reporting features and logistics data management are supported by document processing via Maatwebsite Excel. Through the structured Waterfall approach, all stages—ranging from medicine requirements analysis to system testing—are ensured to run systematically to achieve transaction efficiency and expand the company's marketing reach.
