Although Vetcove has contracted relationships with many of the vendors supported on Vetcove, a vendor's being on Vetcove does not necessarily mean that the vendor supports, endorses, or partners with Vetcove.
Vetcove's relationship is, first and foremost, directly with the veterinary customer. Vetcove acts as an authorized purchasing agent for each and every one of the 7,000+ veterinary hospitals and nonprofits on Vetcove. When these customers sign up for Vetcove, they explicitly authorize Vetcove as their attorney in fact and agent to retrieve their pricing and past orders, and to place orders, on their behalf. A relationship with a vendor is not required for this to occur.
Any organization may or may not formally endorse Vetcove's use among its customers. Vetcove’s relationship is as a service provider to those same veterinary customers. Because of this, Vetcove does not necessarily need a relationship with a given vendor to operate on behalf of the customer.
