Although the banks use highly intelligent software, human errors can have them slip money through their fingers. But it’s possible to find and minimise or prevent these income leakages through concurrent auditing. To succeed in dealing with revenue loss the concurrent auditor thoroughly checks the calculation and authenticity of the various charges. The revenue manual is provided by the client and ICAI both to the appointed auditor to go through so they can decipher the whereabouts of the leakage. Then the auditor produces different MIS reports from the system and analyse them up to the hilt. For instance, if the income leakage arose because the bank has undercharged the fees then the loss of income may result in a fall in market share price due to the weak performance of the bank. Contrary to this if the bank has overcharged the fees, then the false performance can mislead the client and stakeholders. It’s the auditor’s duty to present the true and fair performance report to the auditee.
