• Improves operational efficiency.
• Reduces dependence on manual branch-level processing.
• Supports centralised reporting and monitoring.

5. Main Features of CBS

• Centralised customer database.
• Customer account management.
• Deposit management.
• Loan account management.
• Interest calculation.
• Transaction processing.
• General ledger and accounting functions.
• Integration with payment channels.
• Integration with ATMs and cards.
• Integration with internet and mobile banking.
• Reporting and monitoring.
• Audit trails and transaction records.

6. How CBS Works

A simplified CBS transaction can be understood as follows:

1. The customer initiates a transaction through a branch or digital channel.
2. The request is authenticated.
3. The banking application sends the transaction to the relevant banking system.
