The Japan cash and trade operation does transaction processing for remittances in local / non-resident yen accounts. The customer needs to be billed for services and income booked to appropriate receivable accounts.

Prior to the project, the billing process was distributed across different product processors like (those handling cross border transfer, non resident yen related, mass payments, through post office etc). Wipro’s solution aims to implement a centralized billing system that maximizes automation.

The transaction details would be pushed from the product processors to the billing system as an end of day offline process, which will then calculate the charges based on the transaction type and generate accounting entries. At the end of the billing cycle, customer invoices would be generated by the system and the customer account debits will take place in the bank host.

Customer information and charge information (fixed, transaction and event based) are maintained in the billing system. For transactions that require immediate charge calculation, the billing system's pricing engine would provide the charges in real time.

	Extensive parameterization to accommodate Transaction pricing changes Addition or modification of products
	Capability to create customized invoicing

Technology
Architecture to handle high transaction volume is a pre-requisite. The billing system has offline interface to get transaction data from the mainframe, NT and Unix product processor systems. The processing logic is implemented through stored procedures. The production environment is HP-Unix (v 10.7), Sybase (rel. 11) and iPlanet web server 4.x. Online charging is implemented by replicating the pricing engine on the product processor side using MS SQL server 7.5.
