A vendor scorecard is a short, repeatable way to judge whether a supplier is still worth keeping. Rate each vendor from 1 to 5 on five criteria (quality, delivery, cost, communication, risk), weight them by what matters to your business, review every quarter, and act on the score instead of on the last bad week.
Most small businesses manage vendors from memory. The supplier who caused last month's problem looks terrible, and the one who quietly delivers late every month looks fine because nobody wrote it down. A scorecard fixes that by putting the same questions to every vendor, on the same schedule, with the answers on paper.
What should a vendor scorecard measure?
Keep it to five criteria. More than that and nobody fills it in.
Criterion What you are asking Evidence to look at Quality Did what we received match what we ordered? Returns, rework, complaints, defects found on receipt Delivery Did it arrive when promised? Promised date vs actual date for each order Cost Is the price stable and fair for what we get? Invoice vs quote, surprise charges, price changes Communication Do they answer, warn us early, and fix problems? Response time, whether problems were flagged before or after we found them Risk What happens to us if this vendor fails? Single source or not, contract terms, how hard they are to replaceFormal quality systems lean on the same discipline. ISO 9001, the quality management standard used by more than a million organisations, is about consistently meeting customer expectations, and you can't do that with suppliers you never check. You don't need certification to borrow the habit.
How do you score each criterion?
Use one 1 to 5 scale for everything, and write down what each number means before the first review. Otherwise a "4" from one manager and a "4" from another mean different things.
Score Meaning 5 Better than agreed, no issues this quarter 4 As agreed, minor issues fixed without us chasing 3 Mostly as agreed, one issue we had to chase 2 Repeated issues, or one issue that hurt a customer 1 Not meeting the agreementScore from evidence, not from feeling. If you can't point to an order, an invoice or an email for a score, give it a 3 and start collecting the evidence for next quarter.
How should you weight the criteria?
Weights make the scorecard match your business. A café that buys fresh produce cares most about quality and delivery. A company buying software licences cares more about cost and risk. Pick weights that add up to 100.
A simple starting point:
- Quality: 30
- Delivery: 25
- Cost: 20
- Communication: 15
- Risk: 10
Weighted score = sum of (score x weight) / 100. The result is a number between 1 and 5 that you can compare across vendors and across quarters.
The template
Copy this into a spreadsheet, one row per vendor.
Vendor Category Quality (30) Delivery (25) Cost (20) Communication (15) Risk (10) Weighted score Action Owner Next review Example Ltd Packaging 4 3 4 2 3 3.35 Improvement plan Ops lead 2027-02-15Score each vendor against its own category. Comparing a courier with an accountant on one averaged list hides more than it shows.
What do you do with the score?
The score only matters if each band triggers something.
- 4.0 to 5.0, keep and grow. Tell them they are scoring well. Good vendors rarely hear it, and it makes the next negotiation easier.
- 3.0 to 3.9, watch. Share the scorecard with the vendor and agree on one thing to improve before the next review.
- 2.0 to 2.9, improvement plan. Put the issues in writing with dates. Start quietly looking for an alternative supplier.
- Below 2.0, replace. Plan the exit before you announce it, especially if this vendor is your only source.
Keep the old scorecards. Three quarters of history tells you whether a vendor is improving or just had one good month.
How often should you review vendors?
Quarterly suits most small businesses. Review monthly for a new vendor or one on an improvement plan, and once a year for low-risk, low-spend suppliers. Put the review dates in a calendar, not in your head.
The review itself can take less than an hour for a business with ten main vendors. The time goes into collecting evidence during the quarter, which is why the scorecard should live next to your purchase records.
Common mistakes
- Scoring only when something goes wrong. Then the scorecard is a complaint log. Score everyone on schedule.
- Never telling the vendor. A score the vendor never sees can't improve their work.
- Too many criteria. Ten criteria is an audit. Five gets filled in.
- No owner. Every vendor needs one named person who runs its review.

FAQ
Is a vendor scorecard only for big companies?
No. A business with five suppliers benefits most, because losing one of them hurts more. The template above fits on one spreadsheet tab.
Should I share the scorecard with the vendor?
Yes, at least the scores and the one thing you want improved. Most vendors want to keep the business and will act on clear feedback.
What if a vendor scores badly but is the only supplier?
Treat risk as the real problem. Start an improvement plan, and spend the same quarter finding a second source so you have a choice next time.
Can I add criteria such as sustainability or compliance?
Yes, if they matter to your customers or your regulators. Swap one out rather than adding a sixth, and keep the weights at 100.
