The auditor has to obtain sufficient and appropriate evidence to substantiate his opinion on financial statements. The audit evidence provides grounds for believing that a particular thing is right or not by providing support for a fact or a point in question. The testimonies collected by the auditor must support the contents of the auditor’s report.



The audit evidence is said to be adequate when they are inadequate quantity. The audit evidence enables the auditor to form an opinion on the financial information—sufficient evidence obtained by test checking instead of 100% checking.


The auditor obtains the evidence that is persuasive rather than conclusive; therefore, evidence cannot be 100% authentic. The reliability of audit evidence depends.


Whether the evidence obtained within the organization, i.e., internal and received from outside, i.e., external confirmation by the third party.


Whether the explanation is a verbal explanation from client staff, visual, physical verification of stock, or documentary bills attached to vouchers.


It obtained audit evidence that must connect to the matter being checked. For example, .e.g., the balance stock in hand is correct, and then the relevant evidence shall provide the physical verification.


The following rules of thumb have proven helpful in judging the appropriateness of evidence:

  • Documentary evidence is usually better than testimonial evidence.
  • Audit evidence is more reliable when the auditor obtains consistent evidence from different sources of different nature.
  • Original documents are better than photocopies.
  • Evidence from credible third parties may be better than evidence generated within the audited organization.
  • The evidence made through the auditor’s direct observation, inspection, and computation is usually better than evidence obtained indirectly.
  • The quality of information generated by the audited organization is directly related to the strength of the organization’s internal control; the auditor should have a good understanding of internal controls as they relate to the objectives of the audit.
