Supplier selection does not end with the first order. A business that delivered one good batch may struggle with a larger order or a different variant. A scorecard helps you decide whether to reorder using actual performance instead of familiarity.
Record facts after every delivery
- Quantity ordered, received and accepted as sellable
- Promised date and date inspected stock became available
- Number and type of defects or incorrect items
- Total actual purchase and inbound costs
- Time taken to acknowledge and resolve a discrepancy
- Any unapproved specification or packaging change
Keep the underlying numbers, not only a star rating. “Four out of five” does not explain whether the supplier was late, expensive or inconsistent.
Use clear definitions
Defect rate = defective units ÷ inspected units × 100. Record how many units you inspected. If you inspected only a sample of a delivery, do not present the result as a complete batch count.
On-time order rate = orders meeting the agreed date ÷ orders reviewed × 100. With only two orders, one delay gives 50%; that is a small history, not a stable long-term prediction. Review the reason and severity alongside the percentage.
A fictional comparison
Supplier A delivered 100 inspected units with five defects and resolved the issue after ten days. Supplier B delivered 100 inspected units with one defect and resolved it after two days. If B charges more, compare that premium with the actual costs and customer disruption caused by A. These figures illustrate a method, not a benchmark for an acceptable defect rate.
Make important failures visible
Some issues should trigger a review regardless of the overall score: a safety concern, an unexplained material substitution, missing essential documentation or repeated incorrect variants. A good price should not average away an essential requirement.
For less serious issues, record a corrective action and a review date. “Improve quality” is vague. “Confirm the revised packing method before the next dispatch and inspect those units on arrival” gives both sides something concrete to check.
Review before increasing order size
Check whether the supplier can maintain the same specification and delivery schedule at a higher quantity. Larger orders may use a different production run or require more time. Confirm the terms again instead of assuming a successful small batch proves capacity at every scale.
Keep a backup without creating confusion
For a product your store depends on, maintain a second qualified contact where practical. Test its sample and understand switching costs before an emergency. Keep stock from different suppliers identifiable if their materials or specifications differ, and do not make one product promise that both cannot meet.
Next action: score the latest delivery using real counts and dates. Set one decision: maintain quantity, increase cautiously, request a correction or pause reordering.
