Before you decide to hire any accounting firm, it is important that you are aware that there is a big difference between an accountant and CPA. Below is an excellent explanation from ValueYourMoney.Org of why you should hire a CPA:
CPA vs. non-CPA
Many people do not know how a CPA is different from a bookkeeper or tax preparer. The CPA designation is one of the most widely recognized and highly trusted professional designations in the business world. CPA’s are distinguished from other finance professionals by stringent qualification and licensing requirements. Individuals have worked hard to obtain the CPA designation, and they are committed to working even harder to deliver the value that it conveys.
Why do you need a CPA?
Certified Public Accountants (CPAs) act as advisers to individuals, businesses, financial institutions, nonprofit organizations and government agencies on a wide range of financial matters. Today, many individuals and businesses turn to CPAs for help with tax preparation, personal financial planning, auditing services, and advice on developing effective accounting systems.
What can a CPA do for you?
CPAs are no longer just number crunchers and tax preparers. They are business and financial strategists who help chart the paths of businesses and individuals. Individuals turn to their CPAs for tax and financial planning services, investment advice, estate planning, and more.
Businesses are tapping CPAs to not only manage finances and taxes, but also to determine profitable new product lines, help diversify investments, and provide a variety of other consulting and business services.
