Key takeaways

  • Kansas's central procurement office is Department of Administration, Office of Procurement and Contracts, and vendors register through eSupplier (SMART).
  • Registration fee: not stated on the official pages we reviewed.
  • Registering makes you visible to state buyers; it doesn't guarantee business.
  • Local governments, school districts and universities in Kansas often have their own vendor systems.

How to register, step by step

  1. Gather your information. Have these ready: UNSPSC category codes; FEIN / taxpayer ID (TIN match).
  2. Register in eSupplier (SMART). Start at supplier.sok.ks.gov. Use your exact legal name and taxpayer ID so your record matches tax and payment systems.
  3. 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.
  4. Keep your profile current. Update contacts, codes and documents so notices and purchase orders reach the right people.
  5. Look beyond the state. Cities, counties, school districts, universities and utilities in Kansas often run their own vendor registration and bid systems.

Good to know

Registrations made before May 21, 2018 may have been deactivated and must be redone in the new system.

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.
