The development of a automatic billing system is presented in this paper. Automatic billing system (ABS) consists of digital power meter with GSM (Global System for Mobile Communications). Meter consists of a GSM modem which utilizes the GSM network to send its power usage reading using SMS (Short Message Service) in response to the energy provider’s query about meter reading. At the main server the VB software is used to manage all the received SMSs (meter readings), compute the billing cost, update the database, and to publish billing notification to its respective consumer through SMS or printed postage mailing. A working prototype of the ABS system was build to demonstrate the effectiveness and efficiency of ABS, billing, and notification through the use of GSM network.

Paperless billing is a process that businesses can use to get paid quickly and securely without dealing with the hassles of paper bills and check payments. Paperless bills allow bill delivery and payment to take place completely online, which improves efficiency while reducing costs. Paperless Billing generally involves integrating multiple systems. These include billing system, the banking industry, customer’s paying system, as well as an online interface for the paperless billing system. Paperless billing is most helpful for businesses that send recurring bills to customers. Paperless bills are an option for delivering bills. Bills could be presented as electric documents, such as PDF, or on websites. This gives the customer the ability to review bills before sending payment. Alternately, customers can also set up automated payments in order to pay without even touching a button. We can shop and create bills by using the mobile application. Paperless Bills offer benefits to both the seller as well as the customer. Some of the biggest benefits from Paperless Billing include: Low cost of delivering the bills to customers Better security than paper and snail mail Option for automatic storage of bill When user scans bar code from the product, the user application extracts the product data and displays it on the system application. The user is then asked whether they want to add more products. If user wants to add more products, the user can add it, otherwise user can quit and the bill will be generated and displayed on the screen with the price of the products totaled. The QR code is then generated. The customer can then scan the QR code and the bill will be transferred to the customer’s phone. The bill can be saved by the customer on their phone.

The representative of electricity board monthly come and visits every residential and corporate zone and manually collects the readings from electricity meter. The data is recorded on a piece of paper along with a snap shot of the meter. There after the officials reads the snap shot and readings of the meter and then feed it to the local software for bill calculations. Finally the bills are sent. We as a consumer then make the payment for the received bill. Such a tedious process is this. Man made mistakes can be in huge numbers. Human resources are wasted and many other problems do occur. We finally thought of building a system that will do the above process automatically. The advancing mobile communication technology and the decrease in costs make it possible to combine mobile technology into electricity board automation systems. We propose a system that collects the consuming energy from residential and corporate zones and send it directly to the central-Server. The traditional a...

"Cellular phone services billing for per minute tariff plan and 1-second pulse involve floating point division and multiplication operation to calculate per call bill. Monthly customer billing involves addition operations on per call bills, which are floating point numbers. Round-off errors occur due to floating point numbers’ computer representation limitations and for storing limited significant figures during billing. The study analyzed post-paid itemized bills of a cellular phone service operator in Bangladesh and identified that accumulated round-off error for active post-paid subscribers is significantly high for subscriber group of large number. The research recommends a per second tariff plan to completely eliminate round-off error which also reduces floating point number operations."
