Summary

This chapter focuses on the systematic assessment of customer profitability through detailed revenue and cost analysis. Key techniques include using a customer cost hierarchy to allocate costs accurately and employing advanced variance analysis—covering sales-mix, sales-quantity, market-share, and market-size variances—for actionable managerial insights. Understanding these concepts enables more effective decision-making in pricing, resource allocation, and overall strategy development.

Learning Objectives

1

Describe how purchase volumes and discount practices drive differences in customer revenues.

2

Explain the role of a customer cost hierarchy in allocating costs to customer-level activities and assessing profitability.

3

Analyze advanced variance analysis techniques—including sales-mix, sales-quantity, market-share, and market-size variances—to support managerial decision-making.

4

Evaluate methods for implementing corporate and division cost allocations to enhance overall profitability.

5

Apply the five-step decision-making process to manage and improve customer profitability.

Key Concepts

CONCEPT

DEFINITION

Customer Revenue Analysis

The assessment of customer revenues, emphasizing that variations are primarily driven by differences in purchase volumes and discounting practices.

Customer Cost Analysis

A process in which costs are allocated based on a customer cost hierarchy to determine the profitability of each customer segment.

Customer Cost Hierarchy

A framework used by companies to allocate costs to customer-level activities, recognizing that different customers require varying amounts of resources.

Sales-Variance Analysis

A group of techniques that break down overall sales variance into components such as sales-mix, sales-quantity, market-share, and market-size variances for detailed decision-making insights.

Fully Allocated Costs

Cost figures that include all relevant production, administrative, and support expenses, used to evaluate the comprehensive profitability of customers or divisions.

Example Problems

Example 1

$"$ I'm going to focus on the customers of my business and leave cost-allocation issues to my accountant." Do you agree with this comment by a division president? Explain.

Example 2

Why is customer-profitability analysis an important topic for managers?

Example 3

How can a company track the extent of price discounting on a customer-by-customer basis?

Example 4

"A customer-profitability profile highlights those customers a company should drop to improve profitability." Do you agree? Explain.

Example 5

Give examples of three different levels of costs in a customer-cost hierarchy

Step-by-Step Explanations

QUESTION

How do variations in purchase volumes and discounting practices affect customer revenue?

STEP-BY-STEP ANSWER:

Step 1: Identify the key revenue components: the volume of purchases made by customers and any discounting strategies employed.
Step 2: Compare revenue results across different customer segments to detect variations.
Step 3: Analyze how changes in purchase volumes and the level of discounting contribute to these variations.
Step 4: Conclude that differences in these areas are the primary drivers of revenue discrepancies.
Final Answer: Variations in purchase volumes and discount practices directly influence customer revenue levels, necessitating detailed analysis to optimize pricing and sales strategies.

Customer Revenue Analysis

QUESTION

How is the sales-mix variance calculated and what does it indicate?

STEP-BY-STEP ANSWER:

Step 1: Determine the expected sales mix proportions based on standard or budgeted data.
Step 2: Record the actual sales mix achieved during the reporting period.
Step 3: Calculate the variance by comparing the expected and actual mixes, focusing on the contribution margins of different products or customer segments.
Step 4: Interpret the variance to understand how shifts in the sales mix affect overall profitability.
Final Answer: Sales-mix variance is calculated by examining differences between expected and actual sales mix proportions, providing insights into how these changes impact overall profit margins.

Common Mistakes

  • Misidentifying the impact of discount practices versus purchase volumes on revenue variations.
  • Failing to properly apply the customer cost hierarchy, leading to inaccurate profitability assessments.
  • Overlooking the significance of breaking down variance analysis into its components, such as sales-mix vs. sales-quantity variances.
  • Assuming that fully allocated costs remain constant, rather than recognizing their dynamic role in decision-making.
