Is vendor registration in Idaho free?

The official pages we reviewed didn't state a registration fee. Check sco.idaho.gov for current terms.

Where do I register as a vendor with Idaho?

Register through IPRO powered by Luma (Supplier Portal) at sco.idaho.gov . The central procurement office is Department of Administration, Division of Purchasing.

Does registering guarantee state business?

No. Registration makes you eligible and visible to buyers, and often gets you bid notices, but you still have to compete for contracts or be chosen for purchases under the state's thresholds.

Do local governments in Idaho use the same registration?

Not always. Many cities, counties, school districts and universities run their own vendor registration and bidding systems, so register with the local agencies you want to sell to as well.

How to register, step by step

Gather your information. Have these ready: W-9 signed and dated within the last 90 days; Commodity codes.
Register in IPRO powered by Luma (Supplier Portal). Start at sco.idaho.gov. Use your exact legal name and taxpayer ID so your record matches tax and payment systems.
Describe what you sell. If the system asks for commodity or service codes, choose them carefully: agencies and bid notices often use them to find vendors.
Keep your profile current. Update contacts, codes and documents so notices and purchase orders reach the right people.
Look beyond the state. Cities, counties, school districts, universities and utilities in Idaho often run their own vendor registration and bid systems.

Good to know

Registrations are validated by the State Controller's Office Supplier Portal team; open events can be viewed without an account.

After you register

Registration is the entry ticket, not the sale. Most state purchases above small-dollar thresholds go through competitive bids or existing contracts, including cooperative contracts many agencies use. Watch the state's bid notices, learn which contracts agencies buy from, and start conversations with the program staff who own the problems you solve before a solicitation is written. Our guides to government buying signals and cooperative purchasing explain how.
