How to register, step by step
- Gather your information. Have these ready: Commodity codes; Contact and address information.
- Register in Vendor Self Service (VSS). Start at mevss.hostams.com. 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 Maine often run their own vendor registration and bid systems.
Good to know
Entities that only need payment from the State (not bidding) use the Office of the State Controller's Vendor Activation/Change form (Substitute W-9) instead.
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.
