The project is an application based on the Web where users can get instant electricity bills and pay online by credit card. The system automates the classic process to pay the electricity bill by visiting the place.
The system would be to have two connections admin and user login. Admin can see the details of the user's account and may even add or updated things in their account. Administrator must supply the system with electricity usage data into account the respective users. The system then calculates the invoice of electricity for each user and updates the information on their account each month. The user can then see their electricity bill and pay on the spot before the end of the month. If the user is unable to pay the Bill before the end of the month, it then calculates fine for each subsequent day

Administrator doesn’t have to keep a manual track of the users. The system automatically calculates fine
The system excludes manual bill calculation.
Users don’t have visit the office for bill payment.
There is no need of delivery boy for delivering bills to users place.
Thus, it saves human efforts and resources.
