How to Use This Tool
Compare two vendors with visible criteria weights instead of an unexplained recommendation. Generate weighted vendor scores from price, quality and delivery criteria, preserving every entered weight and rating.
The decision this tool supports
A procurement decision can appear objective while hidden weights or inconsistent scoring scales predetermine the preferred supplier. This page keeps the decision bounded to higher modeled score and the supporting outputs shown beside it. Vendor Scorecard does not import an account, infer a market rate, or silently substitute an industry average.
Inputs and units
The Vendor Scorecard calculation uses Price criterion weight, Quality criterion weight, Delivery criterion weight, Vendor A price score, Vendor A quality score, Vendor A delivery score, Vendor B price score, Vendor B quality score, Vendor B delivery score. Keep all money values in one currency and all time, distance, mass, energy or volume entries in the unit printed beside the field. Mixing Vendor Scorecard scopes can produce a plausible number with the wrong meaning.
- Price criterion weight is entered in points.
- Quality criterion weight is entered in points.
- Delivery criterion weight is entered in points.
- Vendor A price score is entered in 0 to 10.
- Vendor A quality score is entered in 0 to 10.
- Vendor A delivery score is entered in 0 to 10.
- Vendor B price score is entered in 0 to 10.
- Vendor B quality score is entered in 0 to 10.
- Vendor B delivery score is entered in 0 to 10.
Formula and worked check
Weighted score = sum(criterion rating × criterion weight) ÷ sum(weights), calculated independently for each vendor. With 30/45/25 weights, Vendor A scores 7.8 and Vendor B 7.85, so Vendor B leads by only 0.05 points. The Vendor Scorecard default is an executable known-answer case, not a benchmark or recommendation. Change one input and verify that the direction of higher modeled score still matches the stated relationship.
How to interpret the result
Review the component scores and rerun plausible weights; a narrow difference is a prompt for better evidence, not false precision. The additional Vendor Scorecard outputs expose the denominator, comparison, capacity or reverse value needed to audit the primary result instead of presenting one unexplained number.
Assumptions
- All ratings use the same zero-to-ten scale.
- Criteria weights represent the current decision.
- Only the three visible criteria affect the modeled score.
Save the Vendor Scorecard input values and date with any material decision. A later Vendor Scorecard rerun is reproducible only when the same assumptions and units are available.
Limitations and safety boundary
It does not verify evidence, recommend a supplier, model total cost, resolve conflicts of interest or replace procurement and legal review. Vendor Scorecard is an estimate and cannot replace a contract, local code, licensed professional, calibrated measurement, lender statement or platform report where one governs the decision.
