Vendor management system
VMS (Vendor Management Services) is a fairly recent advancement in managing contingent labor spend. VMS is an evolution of the Master Service Provider (MSP) / Vendor-On-Premise (VOP) concept, which became more prevalent in the late-1980s to the mid-1990s when larger enterprises began looking for ways to reduce outsourcing costs. An MSP or VOP was essentially a master vendor who is responsible for on-site management of their customers temporary help / contract worker needs. In keeping with the BPO (Business Process Outsourcing) concept, the master vendor enters into subcontractor agreements with approved staffing agencies.
