2. Criteria for ABC Classification

The criteria for classifying customers can vary depending on the business model and goals. Here are some common factors:

Revenue or Profitability

  • Measure the total revenue or profit generated by each customer over a specific period.
  • Example: A customer who spends 10,000annuallyisclassifiedasA−Class,whileonewhospends10,000annuallyisclassifiedasA−Class,whileonewhospends500 is C-Class.

Purchase Frequency

  • Track how often a customer makes purchases.
  • Example: A customer who buys monthly may be A-Class, while one who buys once a year may be C-Class.

Purchase Volume

  • Consider the total quantity or volume of products/services purchased.
  • Example: A bulk buyer of office supplies may be A-Class, while a small-scale buyer may be C-Class.

Lifetime Value (CLV)

  • Estimate the total value a customer will bring over their entire relationship with the company.
  • Example: A customer with a projected CLV of 50,000 is A−Class,whileonewith50,000isA−Class,whileonewith1,000 is C-Class.

Demographics and Behavior

  • Analyze customer demographics (age, location, income) and behavior (preferences, engagement levels).
  • Example: A tech-savvy millennial who frequently engages with your brand may be A-Class.

  • Data Accuracy: Reliable data is essential for accurate classification.
  • Balanced Approach: Avoid neglecting B and C-Class customers, as they may have growth potential.

5. Tools and Techniques for ABC Classification

  • CRM Software: Tools like Salesforce, HubSpot, or Zoho CRM can automate customer segmentation.
  • Data Analytics: Use tools like Excel, Tableau, or Power BI to analyze customer data.
  • Machine Learning: Advanced algorithms can predict customer behavior and value.

Imagine an e-commerce company with 10,000 customers:

  • A-Class: 1,000 customers (10%) generating $700,000 (70% of revenue).
  • B-Class: 2,000 customers (20%) generating $200,000 (20% of revenue).
  • C-Class: 7,000 customers (70%) generating $100,000 (10% of revenue).

The company focuses on retaining A-Class customers with personalized offers, upselling to B-Class customers, and automating interactions with C-Class customers.
