Are all accounting service providers Insurance agents

I was thinking all Accounting firms provide Financial Planning and If so are all Financial planners are insurance agents.These terms are all inter related and very confusing as what exactly does an accountant do? what is the role of financial planners and what do they do for tax saving. Are all Financial advisors insurance agents. I always believe asking a few questions before hiring a professional. The work for an accountant is to keep tab on the expenses and do bookkeeping. It is always the role of a good accountant who saves extra expenses and the financial planner helps the accountant in making the balance sheets and prepare paper for the tax filing.
Business tax preparation and Company Accounting is very important in terms of the total growth of an organization.The backbone is the finance and if that is not in control then it becomes difficult for any organization to run successfully. So it is always an wise decision to hire an accountant from a reputed Accounting Service providers.
