As a part-time certified public accountant or CPA, your job is to perform bookkeeping and other financial services for your client. In this position, you may record transactions, prepare tax returns, resolve discrepancies in records, or perform other services as required by the employer. The definition of part-time work in this field is not as precise as it is for other jobs. While some part-time CPAs work fewer than 40 hours each week, others may spend a full work week each month preparing reports and processing transactions, then have almost no work for the next several weeks. Part-time CPAs may also work on the weekends instead of weekdays.
