"A bookkeeper records the financial transactions of an organization and takes care of day-to-day functions such as recording sales and invoices, paying bills and processing payroll," Stephens said. "Accountants take the financial data and analyze it to help organizations make financial decisions."

You may also pursue certification programs or use online courses to become a self-taught bookkeeper. Self-taught bookkeepers use a variety of courses, seminars, books, and other online resources to learn about bookkeeping and accounting.

Bookkeeping can be a stressful job, but it doesn't have to be. There are high stakes when managing a business's financial statements, which can lead to stress. However, if you have a rigorous organizational system and a solid knowledge of rules and regulations, it can be straightforward and easily manageable.
