LEX is a complete eProcurement software platform, where eProcurement is described as the business-to-business (B2B) purchase and sale of supplies and services over Web-based networks. An important part of many B2B sites, eProcurement is also sometimes referred to by other terms, such as supplier exchange.

Configurability is a critical requirement for any eProcurement solutions worth adopting within the enterprise. Organizations transform by nature through growth, mergers, or acquisitions; hence their underlying business rules inevitably change.

LEX's flexible design reduces the risk for business operations to be negatively affected by these disruptive forces. With LEX, transactions resume without jeopardizing an organizations ability to connect buyers and sellers regardless of structural anomalies.

LEX makes it possible to automate all buying and selling transactions from customer to generic supplier. Companies deploying the LEX toolset are able to control inventories more effectively, reduce purchasing agent overhead, and improve manufacturing cycles. LEX is driving the trend toward computerized supply chain management.
