Electrical energy requirements have increased in line with economic growth and social welfare. Every month, meter recording officers come to record customers' electricity kwh usage. Problems often occur in the recording process using the ACMT application such as errors in inputting the booth meter numbers or the customer's kwh meter as recorded by the officer. The main problem of this research is how to design a system for recording and calculating postpaid electricity kwh meter bills to produce a report that is fast, accurate, and optimal. This research aims to design a postpaid electricity meter recording system that will provide bill estimates for the customers, and reduce complaints and spikes in customer bills due to recording errors. The design created was tested using the White Box and Black Box Testing method as the results worked according to its function defined.
