Development of a full set of demo data for a Laravel-based SaaS product, an electronic Point of Sale (ePOS) system. Leveraging Laravel Factories, Models, and Seeders, the demo data accurately simulates the operations of three example companies: a pub, a greengrocer, and a street food outlet. Each dataset includes products, categories, sales transactions, customers, and staff information tailored to the specific business type, showcasing the flexibility and capabilities of the ePOS system.
