Tell me about a time when cash remains unapplied and the aging report is misleading. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the bank receipt, remittance advice, and customer ledger and coordinated the action to match incoming cash to the correct invoice and customer account. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
