We hope that the following information will assist you in better understanding the process to be followed to do business with DeKalb County.

Overview of the Purchasing Process

Purchasing & Contracting utilizes competitive bidding processes to procure its goods and services. The two most commonly utilized processes are the Invitation to Bid (ITB) which awards the lowest, responsive and responsible bidder(s) and the Request for Proposal (RFP) which awards the highest scoring, responsive and responsible proposer(s) determined to be most advantageous to the County based on evaluation factors established.


It is the goal of all employees in the Purchasing and Contracting Department to obtain the very best value for every tax dollar spent for the citizens of DeKalb County and to ensure that your visit to this department is productive and pleasant.

Questions Regarding Bids Prior to Opening

Questions regarding Invitations to Bid and Request for Proposal must be submitted in writing, via email to the procurement agent identified in time to allow a written response to all bidders in the form of addenda. This is to ensure that all Bidders receive the same information. Oral explanations or instructions will not be binding.

Submitting Bids

Informal bids (under $50,000.00) may be submitted by email, mail, or in person to the Purchasing & Contracting representative, as requested. Formal sealed bids for items greater than $50,000.00 are to be submitted to the Purchasing & Contracting Department no later than the date and time set for opening. Bids/Proposals received after the opening deadline will not be considered. It is incumbent upon the bidder to ensure that bids are filled out correctly, completely and signed. Double check prices. Ensure that all solicitation requirements are submitted with your bid/proposal.

Awarding of Contracts

Contracts are awarded based on a combination of factors that are most advantageous to DeKalb County.  The County reserves the right to make no awards, one award of all items, or multiple awards of items.  The method utilized to solicit bids and proposals is determined by the estimated dollar value of the individual purchase or the type of commodity or service needed.

Bid Openings

Bid openings are held daily at 3:00 p.m. in the Purchasing and Contracting Department conference room.  Bid openings are public.  You and/or a representative of your firm are welcome to attend whether your firm is engaged in bidding or not.  Information regarding sealed bid prices will be given over the telephone, or written as requested, after they have been opened, abstracted and checked.
