Supplier performance reviews: score the suppliers you rely on

Key takeaways

A supplier performance review scores the suppliers you depend on against a few measures, such as on-time delivery, quality, price stability and responsiveness, and agrees actions where they fall short. Review key suppliers quarterly and others yearly. Gathering the data and preparing the scorecard outsources well; the relationship conversation stays with you.

• Score delivery, quality, price and responsiveness.
• Quarterly for key suppliers, yearly for others.
• Agree actions and check them at the next review.
• Keep the review conversation in-house.

What should a supplier scorecard measure?

Four or five measures you can evidence: on-time and in-full delivery, quality issues or returns, price changes against the agreed terms, invoice accuracy and how quickly problems are resolved. Score each from your own records rather than impressions.

• On-time, in-full delivery.
• Quality issues and returns.
• Price stability.
• Invoice accuracy.
• Responsiveness to problems.

• Which business processes should you outsource?
• Three-way matching: stop paying invoices you should not

Which review work can be outsourced?

Collecting delivery, quality and invoice data, calculating scores, preparing the scorecard, booking review meetings and tracking agreed actions. This is the part that makes reviews happen on time, and it uses data from processes that may already be outsourced, such as purchase order processing.

• Supplier chasing: expedite orders before they slip
• Procurement outsourcing: buy better without a buyer

What should stay with your team?

The conversation with the supplier, decisions about improvement plans, and any decision to reduce business or switch. These depend on the relationship and on what you value beyond the numbers. For larger firms, the Modern Slavery Act also expects due diligence on supply chains.

When are formal supplier reviews unnecessary?

For low-value suppliers that are easy to replace, a yearly check of complaints and prices is enough. Formal reviews are worth the time for suppliers whose failure would stop your business or affect customers.

• Process criticality: rate the damage if it fails
• How much volume makes a process worth outsourcing?

What does this look like in practice?

A pattern we see: owners feel a supplier has got worse but have no evidence to raise it. A scorecard turns a vague complaint into a specific conversation, which suppliers usually respond to.
