Tell me about a time when unrecorded or duplicate transactions remain in cash balance. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the bank statement, cash ledger, and reconciliation detail and coordinated the action to match bank statement transactions to the cash ledger and clear outstanding items. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
