Integrating suppliers into the supply chain is nothing new. Many global enterprises have increased operating efficiency by requiring key players to adopt their integration technologies. Batch-oriented EDI messaging has typically been used to link organizations and, despite some limitations, has been adequate to the task.

Customer integration is altogether different. First, customers expect sellers to conform to their integration methodologies. Second, e-procurement application providers promote access through their particular pathways. Finally, real-time communication is critical because shoppers create purchase requisitions by searching for items online. Connecting to this ever-changing environment presents technical challenges and tremendous business opportunities - including significant gains in top-line revenue, improved operating efficiency, and stronger competitive differentiation.
