The term ‘audit’ refers to the process of examining or inspecting the books of accounts by auditors. After the inspection of books, inventory is physically checked to ensure that all departments are following the required system of documentation. This helps in ascertaining the financial accuracy of the books of accounts provided by the organization.
Internal Audit vs External Audit
The main difference between Internal Audit and External Audit is that the former is done by the employees of the company (Hence the term internal). On the other hand, external audit is done by auditors working for an external audit firm. These auditors are hired by the company specifically for this purpose.
Internal Audit is the kind of auditing conducted by an internal auditor to review the company’s operational activities. This process helps in improving and evaluating the effectiveness of risk management in the company. It also helps in finding out if the company is working in compliance with all the applicable rules and regulations.
External Audit is the audit done by an independent auditor to carefully examine the financial records of the company. This helps in finding out if any of the company’s employees is engaging in embezzlement of funds or fraud and if there is an error in the financial books.

What is Internal Audit?
It is a process to ensure that the organization is complying with all established rules and regulations. Any deviation from the rules and regulations comes to light through this process. It is done by an auditor who also has other roles within the organization.
Internal auditors are answerable to the board of trustees or boards of directors, the audit committee or the accounting officer. Their main tasks comprise the following:
- Assessment of risk management
- Advising management at all levels of the organization
- Confirm information provided and analysis of operations
- Evaluation of risk and controls
- Working with various other assurance providers
It helps the organization to understand various areas of improvement. It helps in identifying control breakdowns, extent of loss, and potential fraud. It keeps a constant check on the staff of the organization. They remain careful with their job due to the fear of internal auditor catching their mistakes.
It plays a significant role in cutting costs. It helps in identifying areas where money is being spent uselessly. This can only be done if the auditor is qualified in these tasks.
However, it is often found that the management is ignorant to the results of internal audit. They often do not take the necessary steps to improve the working of the organization.
What is External Audit?
External Audit is done by independent auditors, external to the organization. Its results are used by people who are not a part of the organization like suppliers, potential customers, etc.
Its objective is to find out if the client is preparing its financial reports as per the required rules and regulations. It also checks if the client is presenting a true financial picture. All companies who trade publicly are required by law to get their financial books audited by external auditors. The main responsibilities of external auditors are as follows:
- To find the real financial and market position of the company
- To validate financial books of accounts and bring to light any error or fraud
- To ensure that the necessary accounting process is being followed
After the gathering of necessary data, the report is given in writing to the concerned parties.
