Book keeping refers to the job of maintaining a company’s financial records, and it is an essential duty of almost every accountant. The work involves handling accounts payable, accounts receivable, payroll, creating balance sheets, and doing other tasks relating to credits and debits. Bookkeepers keep track of how much money an organization earns and how much it spends and owes. These numbers are very important for owners because miscalculations can put a company out of business, so accountants must be extremely detail-oriented. A high level of proficiency in math and statistics is also required for efficient on-the-job performance because the volume of data to be analyzed is usually high, and complex formulas may have to be used to calculate specific figures.
