Single Bill Generation User Story Document

1. Problem Statement

User Role: Billing Manager

Unable to generate bills for individual consumers outside of billing cycles
Forced to wait until the next billing cycle to address consumer disputes or corrections
Difficulty handling mid-cycle activation requiring immediate billing
Delays in revenue collection due to inability to generate off-cycle bills
Inefficient process for handling meter replacements that require immediate billing

Core Problem

The current utility management platform restricts bill generation to batch processing within billing cycles, but there are numerous scenarios where Billing Managers need to generate bills for individual consumers immediately, leading to delays in dispute resolution, revenue collection issues, and an overall inefficient billing process.

2. Who Are the Users Facing the Problem?

Billing Manager

Responsible for generating and managing utility bills
Handles consumer billing disputes and corrections
Manages billing cycles and ensures timely bill generation
Needs to generate individual bills for special cases
Should have full access to the Single Bill Generation feature

3. Jobs To Be Done

For [Billing Manager]: When I need to generate a bill for a single consumer outside the regular billing cycle, But I am restricted to generating bills only during scheduled billing cycles, Help me create individual bills on-demand for specific consumers, So that I can resolve disputes promptly, process mid-cycle activation immediately, and improve revenue collection timing.

For [Billing Manager]: When I need to correct an erroneous bill for a consumer, But I have to wait until the next billing cycle to make these corrections, Help me generate a corrected bill immediately after identifying the error, So that I can maintain consumer satisfaction and prevent escalation of complaints.

For [Billing Manager]: When I need to generate a bill after a meter replacement, But I cannot create an immediate bill reflecting the final reading of the old meter and initial reading of the new meter, Help me create special bills that account for meter changes mid-cycle, So that I can ensure accurate consumption tracking and billing during equipment transitions.

4. Solution

The Single Bill Generation feature provides Billing Managers with the ability to create bills for individual consumers on-demand, outside of regular billing cycles. The solution addresses specific pain points by allowing immediate bill generation in the following capability areas:

Consumer Selection

Search functionality for quickly finding specific consumers by name or account number
Detailed consumer information display with account details and billing history
Verification of consumer category and sub-category information

Billing Period Management

Flexible selection of custom billing periods with precise start and end dates
Ability to set billing periods outside standard cycles
Clear visualization of the billing period being used for the individual bill

Meter Reading Processing

Input of current meter readings for consumption calculation
Automatic retrieval of previous meter readings
Consumption calculation based on the difference between readings
Support for handling meter replacement scenarios

Additional Charges Management

Option to include or exclude outstanding balances
Ability to add late fees when applicable
Support for adding other miscellaneous charges
Real-time calculation of charges summary

Bill Generation and Output

Comprehensive bill summary review before final generation
Preview functionality to verify bill contents
Multiple output options (download, print)
Final bill generation with complete charge breakdown

Billing History Integration

Automatic update of billing history with newly generated bills
Access to historical bills for reference and comparison
Tracking of payment status for generated bills

Audit and Compliance

Tracking of who generated individual bills and when
Proper documentation of reasons for individual bill generation
Maintenance of billing audit trail for compliance purposes
