The electricity meter shows that you need to buy electricity, which means you owe money?

No, the "Please purchase electricity" on the electricity meter indicates that the balance of the electricity meter is insufficient, so it is necessary to purchase electricity in time to avoid affecting electricity consumption. This does not necessarily mean that the arrears have been paid, which is different from the insufficient balance of the electricity meter. Arrears refer to users who use electricity, but fail to pay the electricity bill on time, which exceeds the payment period.
