Internal audits are helpful for small businesses. They can be performed relatively easily without much cost, and the end result is a better understanding of the way your business operates. Companies often hire external auditors in addition to audit themselves . An independent auditor is typically used to avoid conflicts of interest and to ensure the integrity of performing.An external auditor is not affiliated with your company and thus can redirect your company’s behavior without fear of repercussions if you don’t like what he has to say. An external auditor can catch small problems before they become serious and help your business get back on the track. External auditors, however, can observe operations from the outside and determine where the company is wasting time or money. They can recommend behaviors to the company to reduce waste or promote greater efficiency in general as well as tighten accounting practices. External auditors can look at the same factors as internal auditors and double-check their work. They can also train internal auditors in accounting principles by explaining how their analysis differs from the analysis the internal auditor performed.
