Understanding Tail Spend in Procurement
Tail spend represents a significant portion of a company’s procurement activities, often overlooked due to its fragmented nature. This concept is crucial for organizations aiming to optimize their spending and enhance operational efficiency.
Definition
Tail spend typically refers to the purchases that constitute approximately 80% of a company’s transactions but account for only about 20% of the total spend by volume. However, this definition is not universally applicable, as the nature of it can vary significantly across different organizations and even within different departments of the same company.
Characteristics
Common Examples: Office supplies, Maintenance services, Travel expenses, One-time purchases.
Key Features:
- Comprises numerous small transactions
- Often falls below the procurement department’s radar
- Typically involves non-strategic or indirect purchases
- May include maverick spend or misclassified purchases
There is no one-size-fits-all approach to defining tail spend. Organizations should consider the following methods to determine what constitutes tail spend in their specific context:
- Spend Threshold Method: Establish an annual spend limit below which vendors are considered part of the tail spend. This threshold can range from $100,000 to $1 million, depending on the company’s size and overall expenditure.
- Pareto Principle (80/20 Rule): Apply the traditional definition where 80% of transactions representing 20% of total spend are classified as tail spend. Some organizations may adjust this ratio to 70/30 or 90/10 based on their specific spending patterns.
- Unmanaged Spend Approach: Define tail spend as any vendor relationships not actively managed by the procurement department.
