The external window service of urban public utilities (especially water, electricity, gas and heat) is a basic and necessary service for every city. The quality of service can directly affect the image of the city and even the socio-economic vitality. The external window service of urban public utilities is facing thousands of households in the city, and has important characteristics such as universality, diversity, continuity, openness, accuracy, timeliness and convenience. In order to provide high-quality, economical and efficient services to citizens, it has become an inevitable trend for urban public utilities to develop and apply the comprehensive MIS system of the business hall to provide citizens with three-dimensional services such as consultation, complaint, repair and even payment anytime and anywhere.

At present, the urban public utilities in the more developed coastal areas of China have established a business charging MIS system, which generally takes the billing system as the core to realize the counter charging and inquiry services in the business hall, and also provides touch screens to allow users to freely check personal consumption and payment. This MIS system is convenient for users and counter staff in the business hall to a certain extent, but its function is limited. It is mainly reflected in the following aspects:

Due to the continuous expansion of the urban area, it is inconvenient for users to pay fees, so they have to increase business outlets, which increases the burden on enterprises;

Due to the dispersion of business sites, the data of each business site cannot be shared without WAN. Users need to pay fees at the designated business site, which increases the time for users to travel to and from the business site,

In fact, it increases the public cost of society, resulting in waste of resources.  

Due to the limitation of time and place for payment and inquiry, the enterprise's recovery of funds is lagging behind, which affects the operation of the enterprise.  

A good way to solve the above problems is to establish a 24-hour computer voice duty hotline, call center customer service system, web query, touch screen, etc

The system is a comprehensive MIS system of the business hall, which combines the bank's withholding and collection of utility fees, mobile phone's SMS service, and voice inquiry service.
