What should a vendor scorecard measure?

For a small buyer, four things taken from receiving records: did it arrive when it was promised, was the quantity right, was it undamaged, and was the paperwork usable. Price and responsiveness matter too, but they are already visible elsewhere and are much harder to score without argument.

How often should I score suppliers?

Quarterly for most, monthly only for suppliers with enough deliveries that a month is statistically meaningful. Scoring too often produces noise: one bad delivery in a month of four looks like a crisis and one bad delivery in a quarter of forty looks like what it is.

Should I share the scorecard with the supplier?

Yes, and it is most of the value. A scorecard kept privately is a grievance file. One that is sent, with the underlying deliveries listed, is a conversation, and most suppliers will fix a pattern they can see.

On time in full: the percentage of deliveries that arrived by the promised date with the complete quantity. It is deliberately strict, a delivery that is on time but short fails, and so does one that is complete but late, which is what makes it a useful single number.

Does ISO 9001 require supplier scorecards?

It does not require a scorecard specifically. Clause 8.4.1 requires you to determine criteria for evaluating, selecting, monitoring and re-evaluating external providers, and to keep records of the results. A scorecard is simply the most practical way most small companies satisfy that.

Vendor scorecard template, built from records you already have

Q: Vendor scorecard template, built from records you already have

A useful vendor scorecard measures on-time delivery, quantity accuracy, condition on arrival and paperwork accuracy, all taken from receiving records rather than from memory. Score quarterly, share it with the supplier, and use it at renewal. A scorecard built from opinion tells you who is annoying rather than who is expensive.

A printable supplier scorecard scored on delivery data rather than opinion, and the four measures that survive contact with a small operation.

In short

Score from records, not from memory. Memory scores the supplier who was rude on the phone, not the one who quietly costs you a day a month.
Four measures is plenty. Every extra one is a column somebody stops filling in.
Send it. A scorecard nobody sees changes nothing.

Everybody knows which supplier is the difficult one. Almost nobody can show it, which means it never comes up at the point it would be worth money: the renewal conversation.

A worked example of one supplier scored on four measures over a quarter of forty deliveries.
On time		82%
Quantity right		94%
Undamaged		97%
Paperwork usable		88%

A worked example, not a real supplier: one quarter, forty deliveries, scored on the four measures above. The difference between a feeling about a supplier and a number is whether it can be put in front of them, and 82% on time is a sentence a supplier can answer.

The four measures

Measure	Counted as a failure when	Why this one
On time	Delivered after the required date on the order, or outside the agreed window.	The only measure a supplier can never dispute, because both parties agreed the date in writing.
Quantity complete	Any line short against the order, excluding agreed back orders.	Catches the supplier who is reliably a bit light, which is invisible one delivery at a time.
Condition on arrival	Any damage recorded at receipt, whoever caused it.	Damage caused by a carrier the supplier chose is still a fact about buying from that supplier.
Paperwork usable	No purchase order number, no packing slip, or a slip that does not match what was in the box.	The measure nobody tracks and everybody complains about. It costs real minutes at the bay.

Then one combined figure, on time in full: the proportion of deliveries that were both on time and complete. It is deliberately unforgiving, and it is the number worth quoting.

Scoring it without starting an argument

1
Count deliveries, not incidents. Percentages of deliveries are comparable between suppliers. Counts of complaints are not.
2
List the failures with dates and order numbers. A score with no underlying detail gets disputed on principle. A score with six dated examples gets discussed.
3
Exclude what you caused. A late delivery against an order you raised two days before you needed it is your problem, and including it destroys the credibility of everything else on the sheet.
4
Keep the target realistic and stable. A target you move every quarter is a target nobody plans against.

Worth knowing

Do not build a weighted composite score out of five sub-scores with multipliers. Nobody outside the person who built it can tell what changed or why, and a supplier cannot act on a number they cannot decompose. Four percentages and one combined figure is the whole thing.

None of this works without a record of what actually arrived. The columns that make it possible are in the receiving log template.
