E-procurement (electronic procurement, sometimes also known as supplier exchange) is the business-to-business or business-to-consumer or business-to-government purchase and sale of supplies, work, and services through the Internet as well as other information and networking systems, such as electronic data interchange and enterprise resource planning
E-procurement is done with a software application that includes features for supplier management and complex auctions. The new generation of e-Procurement is now on-demand or a software-as-a-service.

The e-procurement value chain consists of indent management, eTendering, eAuctioning, vendor management, catalogue management, Purchase Order Integration, Order Status, Ship Notice, eInvoicing, ePayment, and contract management. Indent management is the workflow involved in the preparation of tenders. In goods procurement, indent generation activity is done online. The end result of the stage is taken as inputs for issuing the NIT. Public sector organizations use e-procurement for contracts to achieve benefits such as increased efficiency and cost savings (faster and cheaper) in government procurement and improved transparency (to reduce corruption) in procurement services. E-procurement in the public sector has seen rapid growth in recent years. An e-procurement system manages tenders through a web site. This can be accessed anywhere globally and has greatly improved the accessibility of tenders.
