Depending on qualifications and a love of numbers and raw data, the financial services sector provides a wide spectrum of careers for power moms. As with attorneys, accounts must have a degree and certification to work, but former certified public accountants (CPA) who opted to stay at home with the kids and are looking to re-enter the work force have a strong foundation for taking on clients from home or working less than five days a week at the offices of a small firm. A power mom with a head for numbers and without an accounting degree can enter the field as a bookkeeper. Taking on a single first client -- a small business owner would be preferential -- is a good first move. As the kinks are worked out and the balance between family and work is steadied, more clients can be added. One of the benefits of bookkeeping is the low overhead it requires. A fax machine, a computer with Internet access and spreadsheet software is virtually all you need. Since we're talking careers, power moms might want to go for a degree in accounting. Reputable online degrees are becoming more prevalent as schools migrate to the Web. It will be worth the investment; in 2008, bookkeepers in the U.S. earned a median salary of $32,510, while accountants earned an average of $65,840.
