That companies outsource myriad business functions is no surprise these days. What is a surprise, however, is the lengths to which public companies must go to ensure that those vendorsโ internal controls donโt become their undoing. Thatโs because, no matter what service is outsourcedโlike payroll, for exampleโresponsibility for financial controls stays in place. But the process of ensuring a vendorโs controls are up to par is not always easy, nor is it cheap. Although a public company can conduct its own audit of a vendorโs controls, some ask suppliers for an audit known as a โSAS 70 Type II.โ
The American Institute of Certified Public Accountants Statement on Auditing Standards 70 set forth the practice for evaluating the performance of outside service organizations. A Type I audit describes the businessโs controls, noting if they are suitably designed and in place. A Type II audit tests those controls and reports if they are working adequately.
