The invention relates to the field of power services, and particularly relates to an online and offline coordinated service handling method based on a power interactive service terminal. The method comprises an online service application step and an offline material scanning step, wherein the offline material scanning step comprises identity authentication, and if the authentication fails, the system will prompt: you are not qualified for service acceptance, please contact servicers; if the authentication succeeds, the system stores customer information and enters next operation procedure; then according to a pre-application service item recorded by the system and corresponding to a login user, an electricity customer scans the required application materials in a terminal scanning area, and the system stores the corresponding scanning result; and after all the materials are scanned and submitted, the application is completed. The method has the advantages that: (1) the method effectively coordinates a 95598 website to jointly complete application of business expansion services, so as to relieve the working pressure of business hall windows and improve the service handling efficiency; and (2) the site of the terminal can be flexibly selected, so that the problem of insufficient coverage of business hall services is effectively solved.
