Auditing is a financial statement audit; it is an assessment of an establishment's financial statements to ensure that the financial records are accurate. This is a form of financial analysis, which is the main emphasis of every commercial venture. They are the key decision-making tools that assist organisations in gaining a clear view of their financial situation.  An audit is a process that involves examining a company's financial statements to determine whether they are complying with laws, regulations and laws. Nowadays, auditors have tried to provide their clients with high-quality services such as auditing and non-audit services. Under financial analysis there are categories and two of which are audit and non-audit, for amateurs these terms would pretty much sound the same except for the word non in obvious cases. There is an understandable distinction between Audit and Non-Audit services what will be detailed further in the article. The three chief methods of audits are external, internal, and Internal Revenue Service audits. CPA firms frequently undertake external audits, which result in the auditor's opinion, which is contained in the audit report. The auditor's opinion, which is neither qualified nor clean, shows that the auditor-general did not receive a significant error in the financial statement analysis. External audits may involve the examination of the organization's financial accounts as well as its internal controls. Management uses internal audit to enhance procedures and internal controls. Further will be the distinction between the Audit and Non-Audit services.

Audit vs. Non-Audit Services

The primary distinction between audit and non-audit services is that audit services are often a legislative necessity for the vast majority of companies, whereas non-audit service needs are optional. Although this is a basic distinction, there are many more, one of which is whether the obligations are voluntary or statutory. The table below will give a much better look at the distinctive attributes of these financial terms.
