How do you charge for utilities in industrial parks?

At present, many industrial parks manually read meters and collect utilities. If the park is large, it is inconvenient to read the meter every month. Our company can install a system, which can not only automatically read the meter and settle the electricity bill, but also allow the merchants to pay the fee first and then use the electricity and water. WeChat Alipay can pay, the balance is insufficient, and you can also automatically remind the arrears by SMS. Like the current mobile phone card, merchants can also check their electricity consumption at any time to avoid disputes.
