Planning and Monitoring your Purchasing Metrics and KPIs

Introduction to Purchasing Metrics and KPIs

Every business professional should periodically pause and reevaluate the key performance indicators (KPIs) that drive purchasing decisions and overall business results. The adage “what you measure is what you get” holds true—defining and tracking the right purchasing metrics ensures you make informed decisions that support your strategic goals.

Purchasing scorecards are not permanent fixtures; they evolve as your business adapts, market conditions change, and new strategies are implemented. This dynamic process requires regular review and adaptation to remain relevant, effective, and aligned with your goals.

How Small Business Owners Learn and Evolve Their Purchasing Process

Many small business owners begin their purchasing journey by focusing primarily on cost but gradually incorporate quality, total cost of ownership, and supplier reliability into their evaluations as their understanding deepens.

Step 1 – Prioritizing COST

• Initial vendor selection is often based on unit price alone.
• While cost is critical, it should not be the sole factor for decision-making.
• In the early stages, evaluating other factors like support or delivery reliability might be challenging.

Step 2 – Emphasizing QUALITY

• With growing experience, business owners assess value for money beyond sticker price.
• Metrics might include customer satisfaction, returned goods, quality control practices, and vendor support for guarantees.
• Quality metrics directly impact customer loyalty and operational efficiency.

Step 3 – Calculating TOTAL COST OF OWNERSHIP (TCO)

TCO encompasses all costs linked to a supplier, directly or indirectly, including:

• Hard costs like price and delivery fees.
• Soft costs such as administrative work, opportunity costs, and financial risks.
• Operational impacts like warehouse handling, stock management, and payment terms.

For example, vendors delivering products to your warehouse may have different TCO compared to those you pick up yourself.

Step 4 – Evaluating RELIABILITY and BUSINESS RELATIONSHIPS

• Assess how easy it is to transact with your suppliers.
• Consider vendor responsiveness, adaptability to your changing needs, and their place in your value chain.
• Metrics include error rates, late deliveries, and willingness to support your business.
• Decisions here influence risk management and long-term partnerships.

Aligning Purchasing Metrics with Business Priorities

Consider each of the four purchasing categories and brainstorm your top three metrics in each area. Focus on quantifiable, straightforward KPIs that you can track and use to evaluate suppliers consistently.

Implementing Your Purchasing Metrics: A Step-by-Step Guide

Step	Action	Example Metrics
1	Identify key purchasing categories (Cost, Quality, TCO, Reliability)	Review supplier contracts and procurement history
2	Define top 3 quantifiable metrics per category	Cost per unit, Return rate, Delivery timeliness

Monitoring and Adapting Your Purchasing Scorecard

Purchasing metrics should be reviewed at regular intervals, ideally quarterly or bi-annually, to ensure they continue to reflect business priorities and market realities. Keep your purchasing scorecard flexible to incorporate innovations, market shifts, and changes in supplier capabilities.

Expanding your purchasing metrics beyond simple cost metrics to include quality, total cost of ownership, and supplier reliability positions your business for sustainable growth and competitive advantage.
