Common Terms

Invitation for Bid (IFB): A method of formal sealed-bid solicitation. Each sealed bid is opened in public at the Procurement Department office at the time designated in the invitation. All bids are read aloud and recorded at that time. A contract is then awarded to the lowest bidder who is determined to be responsive to the County's needs.

Request for Proposal (RFP): A method of formal sealed solicitation that is used for highly technical products or services. In a typical RFP, the County will solicit proposals from prospective contractors on how they intend to carry out the requirement, and at what price. This allows for all proposals to be compared to each other by the County. Responses to an RFP can be subject to negotiation after they have been submitted.

Request for Qualification (RFQ): A formal solicitation for particular types of professional services, such as architectural and engineering services. Firms are rated strictly on technical capabilities, experience, ability to complete the work in a timely manner, and compliance with Small Business Enterprise Program requirements.

Requisition: A formal (written) request for purchase by a department.

Procure: To obtain, secure, purchase, buy or contract.

Purchase Order: A formal (written) authorization form issued by the Procurement Department to vendors, committing the County to buy the goods or services as described on the form. It also defines quantity, delivery date and price.
