A credit clerk provides administrative and financial research support for a business. As a credit clerk, your job duties include reviewing documentation and filings, assessing credit histories and reports, collecting and processing data on existing customers, and preparing documents, such as contracts and liens. You also help customers fill out credit applications. Qualifications include a high school diploma or G.E.D. certificate, which is often sufficient for beginning a career as a credit clerk. Employers may prefer you to have some general work experience and customer service skills. You should also have some familiarity with accounting practices and an eye for detail.
