You can control access via custom claims using the Firebase Admin SDK on your own server of through Cloud Functions for Firebase.

Set claims server side for a specific bid with a method like this:

admin.auth().setCustomUserClaims(uid, {admin: true}).then(() => {
// The new custom claims will propagate to the user's ID token the
// next time a new one is issued.
});

Then set up your database with a structure that separates admin and vendor admin content:

/
   /admin
      /data for admins here
   /vendorAdmin
      / data for vendor admins here
   /staff
      // data for staff here, or perhaps this data is accessible to all since the admins may need access to it.

In the Firebase Console, customize the rules to restrict these locations to those who include the proper claim:

{
  "rules": {
    "admin": {
      ".read": "auth.token.admin === true",
      ".write": "auth.token.admin === true",
    }
    "vendorAdmin": {
      ".read": "auth.token.vendoradmin === true",
      ".write": "auth.token.vendoradmin === true",
    }
    "staff": {
      ".read": "auth.token.staff === true",
      ".write": "auth.token.staff === true",
    }
  }
}

This is a simplified example, so you'll have to customize it further to meet the needs of your app.

You can maintain a users table in your database, and every time you sign up a user just add them there as well, using the uid.
