Tell me about a time when overdue balances are not followed up in time. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the aging report, customer statement, and collection notes and coordinated the action to verify billing, due date, receipt, credit note, and outstanding balance. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
