Overview

During the billing process, there are situations where actual meter readings are not available for all customers. This can happen for various reasons:
  • Meter reading was not submitted.
  • Field staff could not access the property.
  • Smart meter communication failed.
  • Data upload was incomplete.
  • A reading was missed during the billing cycle.
Without a current meter reading, the system cannot accurately calculate consumption, which prevents billing from proceeding. The Estimate Missing Meter Readings process automatically fills these gaps by using historical consumption data and predefined estimation rules configured for each metered service parameter. This ensures that billing can continue even when actual readings are unavailable.

Why Estimation Is Needed

For metered services, bill calculations depend on consumption. Consumption is typically calculated as:
Consumption = Current Reading - Previous Reading
If the current reading is missing, consumption cannot be calculated. Example:
Previous ReadingCurrent Reading
12,500Missing
Since the current reading is unavailable, the system estimates usage using historical billing information and generates an estimated reading.

How Estimation Works

The estimation process identifies customers who are missing current readings and calculates estimated usage based on previous billing history. The system then:
  1. Calculates estimated consumption units.
  2. Derives an estimated current reading.
  3. Marks the reading as estimated.
  4. Makes the record available for bill processing.

Example

Suppose a customer has the following history:
MonthUsage
January450 Units
February500 Units
March550 Units
AprilMissing
The system can use historical usage patterns to estimate April’s consumption. For example:
Estimated Usage = Average of Historical Usage

(450 + 500 + 550) ÷ 3

= 500 Units
The estimated usage is then used to calculate an estimated current reading.

What Gets Updated?

When estimation is performed, the billing system updates:

Estimated Consumption

The calculated usage units for the billing period. Example:
Usage
500 Units

Estimated Current Reading

A new current reading is derived from:
Previous Reading + Estimated Usage
Example:
Previous ReadingEstimated UsageEstimated Reading
12,50050013,000

Estimation Flag

The system marks the reading as estimated rather than actual. This provides visibility during audits and billing reviews.

Supported Estimation Methods

Each metered service parameter can be configured with a specific estimation method. Examples of metered parameters include:
  • KWH
  • M3 Gas
  • Water Consumption
  • Utility Usage
The estimation method is configured when the service or package is created.

Estimation Method 1: Average of Last Year

The system calculates the average consumption from the previous calendar year.

Example

MonthUsage
Jan450
Feb500
Mar550
Dec600
Average:
Total Usage ÷ 12
The calculated average becomes the estimated consumption.

Best For

Customers with relatively stable consumption patterns.

Estimation Method 2: Same Month Last Year

The system uses consumption from the same month in the previous year.

Example

Current Billing Period:
January 2025
Historical Reference:
January 2024
MonthUsage
January 2024700 Units
Estimated Usage:
700 Units

Best For

Seasonal services where consumption varies throughout the year. Examples:
  • Electricity
  • Gas
  • Water

Estimation Method 3: Greater of Average and Same Month

The system calculates:
  • Average of Last Year
  • Same Month Last Year
It then selects whichever value is greater.

Example

CalculationResult
Average Last Year450 Units
Same Month Last Year600 Units
Estimated Usage:
600 Units

Best For

Conservative billing approaches where underestimation should be avoided.

Estimation Method 4: Maximum Usage of Last Year

The system uses the highest recorded consumption from the previous calendar year.

Example

MonthUsage
January450
February500
July900
December650
Maximum Usage:
900 Units
Estimated Usage:
900 Units

Best For

Organizations that prefer high-confidence recovery of potential revenue.

Estimation Method 5: Minimum Usage of Last Year

The system uses the lowest recorded consumption from the previous calendar year.

Example

MonthUsage
January450
February500
March320
April600
Minimum Usage:
320 Units
Estimated Usage:
320 Units

Best For

Conservative customer-friendly estimation strategies.

Example Billing Scenario

Summary

Estimate Missing Meter Readings automatically fills gaps in meter data using historical consumption patterns, ensuring that billing can continue even when actual readings are unavailable.
