Join an industry association such as the National Association of Certified Public Bookkeepers (NACPB). Industry groups often offer online education, such as the NACPB's "Accounting for Small Businesses" and "Bookkeeping Business System" online training courses. Training may be available to the public as well, but members usually receive discounts.
Enroll in an online college or community college offering accounting classes. A two-year (some are only a year and a half) associate's degree program like the one at McKinley College will include core bookkeeping classes, such as introduction to accounting, managerial accounting, computerized accounting, finance and tax preparation, which can all be taken over the Internet.
Log onto a webinar. Webinars are live or pre-recorded seminars, usually between one and three hours, where you are taught by an instructor or go through a video at your own pace. Bookkeeping webinars, such as the "Bookkeeping Basics Webinar" from Your Bookkeeping Made Easy, include topics like learning about a company's bookkeeping cycle, accounts receivable, preparing financial statements, posting general ledgers, and bank reconciliations.
