Do I need a broker?

You should use a broker if one or more of these hold true :-

You are not sure what price to sell your business at
You don't know how to market your business
You are not able to find a buyer willing to pay the right price
You can only find one buyer
You are spending valuable time with multiple buyers, but not getting any offers
You have had several offers fall through before closing

If you have all the above areas under control, you do not need a broker.
