This document outlines the requirements for an inventory management system for a general store. It includes four key user roles: administrator, salesperson, sales manager, and inventory manager. The administrator can add/edit/delete user accounts and product inventory. Salespeople can view inventory levels, search for products, generate bills, cancel bills, return unsatisfactory items, and notify managers. Sales managers oversee exceptions and the inventory manager replenishes stock levels based on salesperson notifications. Data flow diagrams and entity relationship diagrams are also included to design the system's architecture and database structure.
