An accountant is a professional who is responsible for keeping and interpreting financial records. Their job is to prepare them and examine them for any future reference needed. Financial records include but are not limited to: invoices, receipts, ledgers, bank statements, and many more documents.
Accountants and auditors must be able to analyze, compare, and interpret facts, figures, and data. They may use advanced math skills, such as calculus and statistical analysis, for these tasks. The use of probability and statistics is very important for an accountant. These skills and requirements may differ depending on the company.
