    For local businesses

    Looking to get your business listed? You're almost in the right place.

    ChamberOS is the software your local chamber of commerce uses to run their website, directory, events, and member system. Local businesses don't sign up directly with us — you join through your chamber.

    If your town's chamber is on ChamberOS

    Find your chamber's website (it usually ends in .org or has "chamber" in the URL), look for a Join or Membership page, and apply there. Once they accept you, you'll get an invite to claim and manage your own listing.

    • Your chamber decides who joins and at what tier.
    • Dues, perks, and member benefits come from your chamber, not from us.
    • Once invited, you can edit your listing, post updates, sell deals, and RSVP to events directly.

    If your town's chamber isn't on ChamberOS yet

    Send them our way. Forward this page, or just point them at chamberos.org. We're priced specifically for small-town chambers — most are up and running the same afternoon they sign up.

    Common questions from business owners

    Can I sign up my business directly with ChamberOS?

    No. Your business listing lives on your local chamber's site. The chamber controls membership — you join through them.

    How do I find my local chamber?

    Search '[your town] chamber of commerce' — most have a public website. Once you find them, ask about membership.

    I'm already a chamber member but I don't see a ChamberOS login.

    Your chamber will send you an invite email when they're ready to give you access. If you haven't gotten one, ask your chamber's office to invite you.

    Can ChamberOS replace my business website?

    No — your chamber listing is a directory entry on your chamber's site, not a replacement for your own business website.
