Is Vendor Managed Inventory (VMI) Replacing EDI Purchase Orders?

Sun, Oct 16, 2011 @ 12:37 AM / by Shandra Locken

An emerging trend in the world of EDI is the disappearance of traditional EDI purchase orders.  This is due to a new way of doing business called Vendor Managed Inventory (VMI).  What does this mean for the supplier?  Before I address that, let’s look at what Vendor Managed Inventory is.  The website www.vendormanagedinventory.com defines it as, “A means of optimizing Supply Chain performance in which the manufacturer is responsible for maintaining the distributor’s inventory levels.”  So what this means for the supplier or manufacturer is that rather than receiving the 850, which is the traditional EDI purchase order, they will instead receive the EDI 852 point of sale report.  Based on the sales information the 852 point of sale provides, they will send the appropriate product to replenish the shelves.  The retailer then receives an EDI 855 purchase order acknowledgement from the supplier, notifying them of the order.  Occasionally, the 856 advanced ship notice serves this purpose.
