The integrated billing system (IBS) comprise of four modules as Billing, Cash, DPS (data pre-processing system) and MIS. The business logic is pushed on Oracle in form of stored procedures, triggers, functions and packages where presentation layer comprise of JAVA based user interfaces.  The cash for each billing cycle is collected by the banks, post offices, jazz cash, easy paisa, credit/debit cards etc. The MiBS is integrated with smart payment system (SPS) where payment gateway is extended to be integrated with all financial institutes for real time transaction and visibility for the consumers and management.
The month end processing steps during billing are the steps performed to close the current month billing and initializing the billing system DB schema for the next month. This process locks transactional (billing) ledger for any future update and serves as the single source of truth. As the month-end steps run after the billing; hence, starting from 2nd day of each month till 10th day the batch, month-end processing steps are compute intensive task as it is performed in batches. In order to ease the month end processing steps it is proposed to have month-end processing executed at the end of each day in compliance with cash transaction, billing adjustment and misc. postings for each consumer.
