Supplier Evaluation: How to Score and Select Vendors
Supplier evaluation replaces gut feel with a scorecard. Learn the criteria and a simple weighted method to choose the right vendor.
Supplier Evaluation: How to Score and Select Vendors
Quick answer: Supplier evaluation is the structured scoring of vendors against defined criteria — price, quality, delivery reliability, financial stability, and compliance — usually via a weighted scorecard, so selection and ongoing monitoring are objective and defensible.
Supplier evaluation replaces "we've always used them" with evidence. It applies both when selecting a new vendor and when monitoring existing ones.
Core evaluation criteria
- Price & total cost of ownership
- Quality (defect rates, returns)
- Delivery reliability (on-time, in-full)
- Financial stability
- Compliance & certifications
- Responsiveness & service
A simple weighted scorecard
- Assign each criterion a weight that sums to 100%.
- Score each supplier 1–5 per criterion.
- Multiply and total.
The highest weighted score wins — and the same scorecard becomes your quarterly performance review.
The goal is not the cheapest supplier, but the best value supplier over the full relationship.
A rigorous evaluation feeds directly into onboarding and risk management.
