All university purchases must be authorized in advance with a UC Purchase Order or Credit Card.  Supplier may not receive payments or may have their invoices significantly delayed due to an unauthorized purchase. Please ensure you have a Purchase Order from UC before shipping goods or starting services. 

Unauthorized purchases (also known as "after-the-fact" orders), are purchase transactions that are either entered into by an individual who is not authorized to execute agreements on behalf of the UC, or entered into by an individual who has authorization, but who uses an unauthorized procurement method or exceeds their delegated authority.

That authority is limited to Procurement organization Buyers and contract administrators to assure compliance with federal and state law, university policy, and prudent business and financial practices.
