Doing Business With Lake County


Doing Business With Lake County

Doing Business with Lake County is a three step process:
  1. Get Registered - Register your company on the online bid and vendor registration portal. Through this online portal, vendors can download full bid packages, register to receive email notifications about procurement opportunities, post addendum questions, and download plan holder lists. The tool also allows multiple individuals from the same firm to register. All vendors are required to register on the portal.
  2. Get the Business - Submit bids, proposals, or quotes for your products and services. Purchasing will review, evaluate, and make a recommendation. If selected, you then enter into a contract with the County.
  3. Get Paid - Issue invoices for goods and services. The County will make payment within 30 days from the date the invoice was received. The Lake County Procurement Ordinance (PDF) must adhere to State procurement laws which require competitive solicitation of products and services above a certain dollar amount. Payments must be made in accordance with the Illinois Prompt Payment Act.

Purchasing Division

The Purchasing Division works to ensure an open and competitive purchasing process, and assists Lake County departments and agencies in purchasing required goods and services in conformance with the Lake County Purchasing Ordinance. Purchasing also strives to increase awareness about business opportunities, while maximizing participation from Lake County businesses, including women owned and minority business enterprise. 

Lake County invests around $200 million each year on various goods and services including equipment, products, supplies, and services ranging from small to big purchases. Additionally, the County has multi-million dollar construction projects including roads and buildings where products and services are needed. 

Vendor Disclosure  
Effective January 2019 the Lake County Board implemented a Vendor Disclosure and Conflict of Interest Policy, which require vendors to disclose any familial relationships between a Lake County elected official, department director, deputy director, manager and owners, principals or officers of the vendor’s company as well as campaign contributions to County elected officials. Completed forms are included as part of the Awarded Contracts database.
