I am pretty sure most of us have business relationships, it could be a business relationship with a vendor or supplier you get your products and services from, it could with another business owner in the same field as you. One key factor you should always remember when going into these relationships is to ensure that you can actually trust them. Yes these days trust worthy persons are not easy to find but, do not startup a relationship with someone you cannot trust, it would definitely affect the growth of your business in the long run.
