As per Para A11, SA 230, auditor CAN prepare Completion Memorandum or Audit Summary, its optional not at all compulsory.

It is advisable to prepare it in large and complex audits.

Because it helps efficient and effective reviews (by seniors of juniors work) and inspections (after completion for quality testing).

Auditor records significant matters encountered during audit and how they were resolved. It can be prepared in any format, need not be understandable by experienced auditor as it is voluntary.

It also helps next year team to get birds eye view of audit, so they can plan next years audit.

Further I will sending amendments for Nov 15 by month end.
