Become a Vendor

Work with IEI as a subcontractor or supplier.

IEI builds teams from qualified trade partners, specialty contractors, laboratories, and suppliers. Register your company so our project and contracts teams can find you when a requirement matches.

Do not send banking, ACH, or Tax ID documents by email.

Attach your W-9 and Certificate of Insurance directly to the registration below — uploads travel over an encrypted connection into IEI's access-controlled document intake. Banking and ACH information is collected separately: after you register, IEI will send a secure request for your ACH form. Never transmit account or routing numbers in an unencrypted message.
