An inventory system combines web application, barcode scanners, barcode labels, and mobile devices to streamline the tracking of inventory (e.g. consumables, goods, SKUs, supplies, etc.) as product flows through a warehouse environment including a multi-level login system in it. This could be a single stockroom or multiple warehouses spread across the country. Along with this we have an account management system included in it, which looks over all the billing and calculations along with the increment and decrement of the stocks.
