The business charging system realizes unified files, unified charges, unified reconciliation, and unified reports for all users and various meters. It integrates meter reading, charging, meter keeping, accounting and other businesses into a unified management platform, adopting a "three in one" platform operation mode of cloud server+desktop end+APP end, transforming the charging business from "customer errand" to "data errand".

The system design adopts a new perspective of "top-down", with multi-level and multi-dimensional water supply KPI indicators, comprehensively displaying big data analysis such as business fees, management, and performance evaluation, making the charging system more in line with actual business requirements and management needs.
