Audit Assurance services are broader in scope than either audit or attestation services. It is an independent professional service designed to improve the quality of information for the purpose of making better decisions. It evaluates the reliability, credibility, relevance, and timeliness of information. It assesses all the information and determines how accurate it all is. It provides independent and professional opinions that reduce the information risk. Assurance services may involve financial and non-financial services.Audit services could be considered a type of assurance service but they differ in that audit services are only designed to test the validity of the financial statements.An audit service is an official and independent examination performed by an auditor to ascertain the validity and reliability of a company’s financial and accounting records as well as supporting documents and the systems and processes responsible for recording and summarizing that information with the goal of expressing an opinion regarding their fairness and presentation( hindi na ako makahanap ng ibang words, hehe).
