The OAG is composed of Legal, Crime Victim Services, Medical Fraud Control, and Child Support Enforcement programs. The Medicaid Fraud Control and Child Support programs receive federal funding and must meet federal procurement guidelines, in addition to state requirements. The operating costs of other programs are primarily funded by state appropriations.

Although the OAG has offices throughout the state, the agency's purchasing functions are centralized. The Procurement Division is responsible for procuring goods and services to meet the needs of the entire agency.

The OAG purchases a wide variety of commodities and services each fiscal year. Most routine orders for items such as office furniture, equipment, and supplies, are made through term contracts established by the Comptroller of Public Accounts (CPA). Computer and telecommunications related purchases are made through the Department of Information Resources (DIR) Co-op contracts which make up a significant portion of the agency's expenditures.
