Vendor scorecards: what to measure and why
A practical vendor scorecard framework: price, service, risk, compliance, and performance, with weights and a review cadence.
Most vendor decisions are made on price and then defended with anecdotes. A scorecard makes the trade-offs visible before the contract is signed and gives you a reason to review the vendor later.
Why a scorecard
A scorecard turns a vague comparison into a repeatable decision. It also protects the person making the decision: if a cheaper vendor is rejected, the reason is documented.
The scorecard should be simple enough to use in a 30-minute meeting. If it takes a day to fill out, it will not be used consistently.
Five criteria
Price is only one dimension. A vendor that is cheap but unreliable costs more in management time and downtime. Use five criteria and define what good looks like for each.
- Price: total cost, not just the headline quote
- Service: response time, quality, and communication
- Risk: continuity, security, and dependence on one vendor
- Compliance: contracts, insurance, data protection, and certifications
- Performance: delivery against agreed SLAs and outcomes
Set weights before you score
Decide the weights before you see the vendor scores. Otherwise the weights will quietly bend toward the vendor you already prefer. A simple 1–5 scale is enough.
For a cleaning vendor, service and reliability may matter more than price. For a one-off furniture purchase, price and delivery may dominate. The weights should reflect the risk, not the category.
Score with evidence
Every score should have a note or a document behind it. “Service: 4” is not evidence. “Responded to two urgent requests within four hours; one missed SLA in Q3” is evidence.
If you cannot find evidence, score lower and mark it as an assumption. A scorecard built on assumptions is still useful, but only if the assumptions are visible.
Review cadence
Review high-risk or high-spend vendors quarterly. Review low-risk vendors annually. Use the same scorecard so you can compare trends, not just snapshots.
The review should produce one of three decisions: keep, improve with an action plan, or replace. A review with no decision is a status meeting.
Common mistakes
The same mistakes show up across offices. Avoiding them is more valuable than adding more criteria.
- Scoring only on price
- No risk or compliance criteria
- No named owner for the vendor
- No review cadence
- Weights changed after the scores are known
