What are Inventory management systems?

Inventory management software is a computerized system to manage, track the number of stored goods. Inventory management is a major part of supply chain management.

Inventory management solutions keep track of the goods while moving through the process or stored in the warehouses. It saves all the details including serial numbers, barcodes, costs, location, the number of goods, events date for every step in the process.

Most of the ERP "Enterprise resource planning" systems have Inventory management as an internal package. As well as many eCommerce solutions.

Sometimes small and medium-size businesses use Excel to make it simple for managers to keep everything organized in a simple portable popular format. However, it can be a nightmare with rich warehouse and dynamic supply chain or a popular eCommerce site.

Ms.Excel and other open-source spreadsheet programs can be used to manage inventory for small and medium businesses. however, it sometimes requires a spreadsheet guru to create his tools and templates.

The advantages of using Microsoft Excel and open source spreadsheet programs or office suites (LibreOffice) are: the files will be portable, easy to understand and manage, can be used on cloud-based offices like Google spreadsheet and Microsoft cloud office services. On the downside, it'll consume hours while the dynamic supply chain process gets more complicated. So here come inventory managers.
