Frequently Asked Questions

Registering as a bidder is a streamlined process that provides for notification of solicitation opportunities for UNSPSC codes in which your organization is registered.

Registering as a supplier is a full registration that allows you to do business with the State of Oklahoma. In addition to notification of solicitation opportunities for UNSPSC codes in which your organization is registered, you also provide information about your organization including diversified organization certification, EFT/direct deposit, etc. Your organization must be fully registered as a supplier prior to receiving a contract award.

Registering as a payee is for organizations or individuals receiving payments from the state but not selling products or services to the state.

EFT/direct deposit registration is required for suppliers and payees.

Oklahoma embarked on a statewide project, the Oklahoma Supplier Portal, to bring all our supplier processes online. This allows suppliers to manage their own accounts, bid on upcoming projects and manage the work performed with the state. Registration enables a closer working relationship with the State of Oklahoma.

You can register as a supplier, bidder or payee in the Oklahoma Supplier Portal. Training materials on the registration process are located on the Supplier and Payee Training web page.

While existing contracts and services will continue without interruption, the management of your organization’s account information will move to the new Oklahoma Supplier Portal. If you have not registered in this new portal, you will need to register again to access and maintain your information. The new portal went live in October of 2022, and you must have registered in the new portal after that date. Through the portal, you will also manage any future projects you bid through your account.

Information about Limited Liability Companies and the Taxpayer Identification Number can be found here, and states:

For federal income tax purposes, a single-member LLC classified as a disregarded entity generally must use the owner's social security number (SSN) or employer identification number (EIN) for all information returns and reporting related to income tax. For example, if a disregarded entity LLC that is owned by an individual is required to provide a Form W-9, Request for Taxpayer Identification Number (TIN) and Certification, the W-9 should provide the owner’s SSN or EIN, not the LLC’s EIN.

This does not mean that the contract or payment must be to the parent company. It is for tax purposes only. 

Check that you are registered for the correct category codes and that all of your contact information is correct in your supplier account.
