The focus of SMG Business Services is proactive and preventive. 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 issues 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.

All business owners are empowered to be the best entrepreneurs they can be through reliable, trustworthy, and accessible accounting.
— Silvia M. Guardado, EA, Owner - SMG Business Services


To provide an efficient and effective bookkeeping, training, tax and consulting service as well as professional knowledge and expertise to maintain company’s accounting records up-to-date to relieve the business owner so that they can do what they do best.


All of our clients are treated with the respect and integrity they deserve. We offer personalized services at competitive prices, fast and accurate turn-around times, and professional expertise on your business, bookkeeping, and tax related issues.


We believe that financial success depends on how well your bookkeeping system is setup, executed and administered. The “Books” are the pulse of any business. They measure the financial health and growth potential, along with many other important aspects that are keys to your overall success.

It’s not “One Size Fits All.” Every business is different and unique. So are the needs of their owners, management, and employees. If the “Books” are not setup and maintained correctly from the start, vital information may be over looked, ignored, not reported, or reported incorrectly. Not only can that cause serious financial and cash flow problems, it could lead to major tax issues and a host of other unnecessary financial or legal oversights.
