Common red flags and mistakes

- Ignoring audit observations after report completion.
What to mention when you post
- Entity type, turnover and financial year.
- Audit type and deadline.
- Whether books are final or need cleanup.
- Previous year audit remarks, if any.
- Whether ROC/tax filing support is also needed.
How to choose the right professional
- Confirm qualification and signing/certification scope.
- Ask for document checklist before starting.
- Clarify whether accounting cleanup is included.
- Check experience with your entity type and industry.
- Insist on timeline and query resolution process.
Extra checks before you finalise
- Before audit work starts, ask for a query list format and owner for each pending document so delays are visible.
- Confirm whether the engagement covers only review/reporting or also correction entries, schedules and management responses.
- For businesses with inventory, loans or statutory dues, insist on separate schedules because these are common sources of audit observations.
