Night Audit is a common activity which is carried out by authorized persons such as Admin or Auditor. That is you must be privileged to audit. The auditor at the end of the day can do the audit on hotel transaction activities carried out on that day and get back to the management if found something improper. The software does not force the auditor to audit routinely, that is daily, but logically he cannot proceed the auditing for forthcoming days unless he finishes auditing for the previous days. The auditor can do audit for exactly one day at a time and exactly once. ASIFD is so economical that you can opt to print the reports for auditing only if necessary. Alternatively you can preview the reports.
