An audit firm provides auditors with the necessary tools and information to make an independent analysis of an organization’s financial records. An audit firm is not an audit agency per se, since its main function is to perform assessments and provide recommendations based on its current knowledge. An audit firm may be part of an organization’s internal audit service or wholly independent. However, these firms tend to focus on only one aspect of internal audit, such as third party verification of accounting transactions or the identification of areas for improvement in accounting practice. Organizations rely on third-party audits more than internal audits, which are conducted by the same people who perform the internal audits.

In many countries, auditors have to be licensed by the government in order to conduct examinations. Some countries also require that audit firms comply with the standards laid down by the International Association of Certified Public Accountants (IACPA) and the American Institute of Certified Public Accountants (AICPA). Most audit firms follow the code of principles laid down by the U.S. Securities and Exchange Commission (SEC). The audit guidelines set forth minimum standards for assessment of the effectiveness of internal control and fraud prevention and focus on the detection and prevention of any fraudulent transactions. Auditors also follow guidelines provided by the AICPA.
Before an organization can hire an audit firm, it must first establish its requirements. These requirements may include a letter of appointment from the CEO and a copy of the organisation’s charter. The audit firms may also need to furnish additional information, including copies of relevant documents, such as compliance manuals, operating procedures, and business strategies. Auditors may also be required to provide a proposal describing their proposed methodology and results of the examination.
After establishing the required conditions, an organisation will need to select from among the available audit firms. When selecting an audit firm, it is important to choose one that has expertise in the areas that are important to the company. Some of the areas that audit firms should concentrate on include internal control issues, external fraud protection, public sector fraud, effective and efficient debt collections, and fraud in the healthcare industry.
It is also important to determine whether the audit firm will be responsible for the creation and maintenance of the audit database. The database is used to store information about the clients and the activities performed against them. The audit firm must also create a final report that includes recommendations to improve the company’s management systems, internal controls, and audit function. The audit report is also used for regulatory reporting and for evaluating the effectiveness of the company’s anti-fraud practices. All reports and materials produced by the audit firm should comply with the AICPA policies and principles.
Generally, audit firms may have two types of clients: large companies and small organizations. The size of the company dictates the scope of auditing and the types of activities that will be covered. Larger companies typically hire the services of larger audit firms, while small organizations may decide to audit themselves. There are many examples of independent auditor firms, such as PwC, KPMG, and Delsey. In addition, there are several examples of internal audit firms, including CIG, KPMG, Price Waterhouse Coopers, and Bean Bag Coopers.
