Welcome to SMG Business Services

number crunchThe focus of SMG Business Services is proactive and preventative.  We want our clients to know as soon as possible whether their business has generated income so that they can improve on what they are doing well or immediately take corrective action.  Whether the problems are managerial, financial, regulative, or governmental; these problems need to be prevented so that business owners can focus on what they do best instead of spending their time fixing them.

We believe in proactive bookkeeping.  Books and records should always be up to date so that business owners can be free to make well-informed and timely business decisions.
