ABC Classification

ABC classification is a method of categorizing products based on their importance to your business. StockWise automatically classifies your products to help you prioritize inventory management efforts.

What Is ABC Classification?

ABC analysis divides products into three categories based on their contribution to total sales:

ClassDescriptionTypical Percentage
AHigh-value, critical itemsTop 20% of sales
BModerate importanceNext 30% of sales
CLower priority itemsRemaining 50% of sales

The Pareto Principle

ABC classification is based on the Pareto principle (80/20 rule):

  • Roughly 20% of products generate 80% of revenue
  • These are your "A" class items

How StockWise Calculates Classes

Class A Products

Products that collectively contribute to the top portion of your sales revenue.

Characteristics:

  • Highest sales volume or value
  • Most impact on revenue
  • Critical to business success

Management approach:

  • Monitor frequently (daily if possible)
  • Maintain higher safety stock
  • Prioritize accurate forecasting

Class B Products

Products with moderate contribution to sales.

Characteristics:

  • Steady, reliable sellers
  • Important but not critical
  • Moderate impact on revenue

Management approach:

  • Regular monitoring (weekly)
  • Standard safety stock levels
  • Normal forecasting priority

Class C Products

Products with lower individual contribution but often numerous.

Characteristics:

  • Low individual sales
  • Large number of items
  • Lower revenue impact

Management approach:

  • Less frequent monitoring
  • Lower safety stock acceptable
  • Simplified forecasting

Limitations

Dynamic Classification

Product importance can change:

  • Seasonal variations
  • New product launches
  • Changing customer preferences

StockWise recalculates classifications periodically.

Revenue vs. Volume

Classification is based on revenue contribution. A high-volume, low-margin item might be Class B or C despite selling frequently.

Strategic Products

Some products may be strategically important beyond their revenue:

  • Loss leaders
  • Complementary products
  • New market entries

Consider business context alongside ABC class.

Best Practices

Focus on A Items

  • Review A-class items daily
  • Maintain accurate inventory counts
  • Keep higher safety stock

Don't Ignore C Items

  • C items still contribute to sales
  • Customer may need these products
  • Balance effort, don't eliminate attention

Review Classification Periodically

  • Sales patterns change
  • New products enter the mix
  • Reassess quarterly
