How to register as an Indiana vendor, step by step
These are the steps as the state describes them, in plain words. The portal may word things differently, and it can change, so keep the official page open beside you.
- Check the Registered Bidders List to see whether your company already has a bidder profile.
- If not, create a bidder profile by completing the Bidder Registration Application (IDOA publishes a step-by-step guide); the primary contact's email becomes the Supplier Portal login.
- Choose UNSPSC codes for what you sell (IDOA links an About UNSPSC page).
- Send the State Comptroller a W-9 and an Automated Direct Deposit Authorization Agreement.
- Register your business with the Secretary of State through INBiz, unless you are a sole proprietor or partnership.
- Use the Supplier Portal to view and answer bids, update your profile, report subcontractor payments in Pay Audit and apply for IDOA programs; watch the Current Business Opportunities page.
What to have ready before you start
Registration goes faster when the basics are in front of you. For Indiana, gather:
- Your legal business name exactly as it appears on your tax records, and any trade name you use.
- Your federal Employer Identification Number (EIN), or a Social Security number for a sole proprietor, since the state uses it to match you for payment.
- A business address, a phone number and an email address that someone reads every day; bid notices and questions from buyers go there.
- A short list of what you sell, so you can choose the matching UNSPSC codes in one sitting.
- W-9 and direct deposit authorization to the State Comptroller
- Secretary of State registration through INBiz (not required for sole proprietors or partnerships)
- State ethics rules under IC 4-2-6 and 4-2-7
- IT vendors: Indiana RAMP policy (effective Oct 14, 2025)
Does it cost anything to register in Indiana?
No fee is stated on the official pages we read: No fee stated on the official page. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and Indiana does not require you to use a paid middleman to sell to its agencies. Some separate things can cost money, such as a notary for a form, a professional license, insurance or a bid bond on construction work.
Which commodity codes does Indiana use?
Indiana matches vendors to bids with UNSPSC. UNSPSC is the United Nations Standard Products and Services Code, a four-level product code set. Choose the most specific codes that match your goods or services; buyers send bid notices by these codes. If you also want federal work, you will need NAICS codes for SAM.gov; our free NAICS code lookup and the guide what a NAICS code is help you pick them.
Cities, counties and school districts in Indiana
Cities, counties and school districts usually run their own purchasing and bid lists, so registering with the state does not put you on every local list.
Large local governments in Indiana include Indianapolis, Fort Wayne. Each one usually keeps its own vendor list and posts its own bids, so register with the ones you want to sell to as well.
EasBid reads many of these local sources together with the state's, so one search shows state and local bids side by side.

Tips for your first Indiana bid
- Read the whole solicitation before you price anything; the due date, the question deadline and the submission method are usually on the first pages. Our guide on reading a solicitation shows what to look for.
- Ask questions in writing before the question deadline. Answers are usually posted as an addendum that every bidder can see.
- Check whether the bid needs a license, insurance certificate or bond, and get those started early.
- Submit through the channel the notice names, IDOA Bidder Profile registration and the Supplier Portal or otherwise, and leave a day of margin; late bids are normally rejected.
- Whether you win or lose, ask for the award results. They show the winning prices and help you price the next one.
