edX. Course Description: edX provides a host of free bookkeeping courses through the Association of Chartered Certified Accountants (ACCA). Topics include an introduction to bookkeeping, intermediate bookkeeping, financial accounting and introduction to management accounting.

Self-taught bookkeepers use a variety of courses, seminars, books, and other online resources to learn about bookkeeping and accounting. You can also learn how to use accounting software, like QuickBooks, which can teach you about the basics of bookkeeping as well as the technology used by many businesses.

To learn these skills and others, new bookkeepers often receive around six months of on-the-job training to learn how to use bookkeeping software, databases, and spreadsheets. Though bookkeepers don't need to hold college degrees, some may see their salaries increase after completing an undergraduate degree.
