Start an Accounting Business and work for businesses & individuals preparing their financial reports, accounts receivable/payable, payroll, tax planning and preparing financial forms.
If you are a Certified Public Accountant, you can charge more for your work, as your level of education and expertise are higher.
You should be very comfortable working with numbers, and be detail-oriented. Organization is a must.
You'll need a fax machine, copier and computer with spreadsheet, word processing and database software. An adding machine is also useful for tallying up receipts.
Additional software and reference books, such as the yearly tax guide, will also be needed depending on the range of services you will provide.
