What Is Supplier Scorecard?
Also known as: vendor scorecard, supplier performance rating, vendor rating, supplier KPI
Definition
A supplier scorecard is a periodic rating of a vendor against agreed measures such as on-time delivery, quality acceptance, price performance and responsiveness. It turns receipt and quality data into a score used for sourcing and corrective action.
Supplier Scorecard Explained
A scorecard converts supplier behaviour into comparable numbers. The common measures are on-time delivery against the promise date, in-full delivery, quality acceptance rate or parts per million defective, price variance against the standard or contract, and responsiveness to changes and corrective action requests. Each measure gets a weight, and the weighted total gives a score and often a rating band.
Most of the inputs already live in the ERP. Delivery comes from PO promise dates and receipt dates. Quality comes from inspection results and returns to vendor. Price variance comes from the gap between PO price and standard cost. SAP has vendor evaluation with weighted criteria, Odoo and NetSuite rely on reports or saved searches, and Infor LN and SyteLine users typically build the calculation in reports or an external BI tool because the logic is customer specific.
The definition matters more than the tool. Decide whether on-time means the original promise date or the last confirmed date, how early receipts are treated, and whether the buyer's own late changes are excluded. If these are not fixed, suppliers will dispute the scores and ignore them.
Scorecards work best when reviewed with the supplier on a regular schedule, tied to consequences such as more volume, probation or requalification, and kept simple enough to read in one page.
Why It Matters
- It gives sourcing decisions an evidence base instead of anecdotes about the last late shipment.
- Persistent low scores trigger corrective action requests and can feed supplier requalification, which several quality standards expect.
- Visible scores motivate suppliers, especially when volume depends on them.
- It connects purchasing, receiving and quality data into one view that few teams otherwise see.
In Practice
A supplier delivered 46 of 60 lines by the confirmed date, which is about 77 percent on time. Of 12,000 pieces received, 60 were rejected, or 5,000 PPM. With weights of 40 percent delivery and 40 percent quality plus 20 percent price, the score falls into the watch band and an improvement plan is requested for the next quarter.
Frequently Asked Questions
What metrics belong on a supplier scorecard?
Usually on-time and in-full delivery, quality acceptance or PPM, price variance, and responsiveness. Some add cost of poor quality, lead time and sustainability measures.
How often should supplier scorecards be reviewed?
Monthly for data collection and quarterly for supplier reviews is common. Critical suppliers may be reviewed more often.
Is a supplier scorecard required for ISO 9001 or AS9100?
Those standards require controlled evaluation and monitoring of external providers. A scorecard is a common way to show it, but the standard does not mandate a specific format.
Related Terms
Approved Vendor List (AVL)
An approved vendor list (AVL) is a controlled record of suppliers qualified to provide specific items, services or processes. Buyers may order only from listed sources, and changes require quality approval.
First Pass Yield
First pass yield is the percentage of units that complete a process correctly the first time, without rework, repair, or retest. Units that eventually pass after rework are excluded, so the metric captures hidden factory loss.
Purchase Order (PO)
A purchase order (PO) is a document a buyer issues to a supplier committing to buy specified items or services at agreed quantities, prices and delivery dates. In ERP it drives receiving, invoice matching, open commitments and supply in MRP.
ISO 9001
ISO 9001 is the international standard specifying requirements for a quality management system, enabling an organization to consistently provide products and services that meet customer and regulatory requirements and to improve through a process-based, risk-aware approach.
AS9100
AS9100 is the quality management system standard for the aviation, space, and defense industry, published by SAE and the International Aerospace Quality Group, which incorporates all of ISO 9001 and adds sector-specific requirements for safety, configuration, and risk.
