VRM stands for Vendor Relationship Management. VRM tools provide customers with both independence from vendors and better ways of engaging with vendors.
To vendors, VRM is the customer-side counterpart of CRM (or Customer Relationship Management). VRM tools provide customers with the means to bear their side of the relationship burden. They relieve CRM of the perceived need to "capture," "acquire," "lock in," "manage," and otherwise employ the language and thinking of slave-owners when dealing with customers. With VRM operating on the customer's side, CRM systems will no longer be alone in trying to improve the ways companies relate to customers. Customers will be also be involved, as fully empowered participants, rather than as captive followers.
