Problem
Retail operations need reliable sales and inventory workflows across stores, users, warehouses, and daily reporting periods.
My Role
Designed the application workflow, backend, relational data model, access control, deployment, and production support.
Architecture
Built reusable PHP and MySQL POS products designed for deployment on shared hosting or Linux VPS environments.
Key Features
- Store-aware users, products, stock, customers, and suppliers.
- Sales transactions, receipt printing, returns, and stock restoration.
- Purchasing, restocking, operational cash flow, and reporting.
- Role-based access for administrators, cashiers, and warehouse users.
Technical Challenge
Protecting stock accuracy as sales, returns, purchases, and manual adjustments affect the same inventory records.
Outcome
Produced a maintainable POS foundation that can be adapted to retail and service-business workflows.
