Development of a Web-Based Pharmacy POS

I need a web-based point-of-sale (POS) system for a pharmacy, complete with product management features (including units like pcs, tablets, bottles), transaction recording, receipt printing, and a stock prediction module using methods such as averages or time series. The system should be responsive, user-friendly for cashiers/pharmacists, and include an admin dashboard to monitor sales and inventory data. Laravel is preferred for the backend, and the frontend can use a modern template or frameworks like Bootstrap, Vue, or React. Full documentation and source code must be provided.
