Selling to the State of Idaho

Purchasing portal, certifications and where to get help

How a company registers as a supplier with the State of Idaho, the state's certification programs, and where to get help in Idaho, with the official sources. Federal registrations such as SAM.gov are in the federal guides.

Purchasing portal

IPRO - Powered by Luma (Idaho's online procurement system)

How to register

  1. Open IPRO. Go to the State Controller's Office (SCO) website at sco.idaho.gov, click Sign In under Online Applications, and choose IPRO - Powered by Luma. The Division of Purchasing website (purchasing.idaho.gov) also links to IPRO under Bid Opportunities.
  2. Click 'Register as a Supplier'. A Supplier Registration Quick Reference Guide is on the IPRO home page under Links and Attachments.
  3. Register once per company. The Division of Purchasing says suppliers are limited to one account per valid Tax ID, and both an Employer Identification Number (EIN) and a Social Security Number (SSN) are accepted.
  4. Fill in the required fields: user name, password, first and last name, main phone number, email address and company name, then Tax ID type, Tax ID, country and mailing address. The State Controller's Office (SCO) suggests using the email address as the user name. SCO's registration guide says passwords need at least 14 characters, with one uppercase letter, one lowercase letter and one number.
  5. Attach a Form W-9 (the IRS taxpayer ID form) signed and dated within the last 90 days in the 'Attach Tax Certification' field, according to SCO's IPRO instructions.
  6. Pick commodity codes that describe what the company sells. The Division of Purchasing says goods use codes 0 to 69 and services use 70 and above, and that choosing codes at the segment and family levels helps the company get every relevant bid notice.
  7. Wait for validation. SCO's Supplier Portal Administration team validates each registration in the order received. SCO says a validated account is needed to submit bids, but anyone can view open bids under the Open Events tile without an account.
  8. After an award, register and complete verification in PaymentWorks, Idaho's vendor management platform. The Division of Purchasing says the Form W-9 in PaymentWorks must match the one in IPRO and that verification could take up to a few weeks. It also says contract finalization needs an updated Certificate of Insurance (COI) that matches the insurance requirements in the solicitation.
  9. For help, email supplierportal@sco.idaho.gov or call the State Controller's Office at 208-334-3100, option 5.

State certifications
