Cost overall process management system

The invention relates to a cost overall process management system, which belongs to the technical field of power grid engineering and comprises an approval work flow module, a statistical query module, a data management module, a data verification module and a data feedback module and is used for feeding back contents input by auditing personnel and generating and exporting a feedback table. According to the method, existing data are collected, compiled and screened, flow nodes of all stages of the cost can be taken into consideration, auditing personnel and supervisor personnel can visually grasp the actual progress situation of a cost engineering project at the present stage, whole-process digital management of cost information is achieved, various self-defined summary statistical tables and documents can be automatically generated, and the construction efficiency is improved. The data can be flexibly screened and exported, data input errors caused by human reasons can be effectively reduced, and the workin
