It is good to have accreditation; it does not necessarily have to be from BBB. In fact, you will find companies that have an F rating of BBB have an A+ rating somewhere else. The difference all lies in the way an accreditation company configures the ratings. BBB rating, or any other credential rating for that matter, is good for any kind and any size of business. Having accreditations helps in building customer trust, and that directly influences sales.
