Overview

A web-based business system that centrally manages products, inventory quantities, inbound/outbound shipments, inventory transfers, stock counts, suppliers, locations, and storage areas for companies and stores. Beyond simply displaying current inventory, it enables tracking of "when, who, which product, and why inventory was increased or decreased" through inventory ledgers and audit logs. #Personal Development
