📋 Supplier Scorecard & Weighted Evaluation

Score competing suppliers against weighted criteria and rank them objectively — the weighted-point vendor-evaluation method taught in CPSM and CIPS. Set your weights, enter a 1–10 score per criterion, and get a defensible, audit-ready recommendation.

1 Criteria, weights & supplier scores

Edit criteria names, set each weight (must total 100%), name your suppliers and rate each on a 1–10 scale. Tap the 🚩 in a criterion row to mark it critical (e.g. Risk/Compliance) — suppliers scoring below the minimum on a critical criterion are flagged.

A supplier scoring below this on any 🚩 critical criterion is flagged as a knock-out risk.
Auto-normalise rescales your weights so they sum to exactly 100% before scoring.
Total weight: 100%
Up to 5 suppliers and any number of criteria. Scores: 1 = poor … 10 = excellent for every criterion (already direction-consistent, including price — score a cheaper / better-value quote higher).

How the weighted supplier scorecard works

A weighted scorecard turns a subjective "gut feel" supplier choice into a transparent, repeatable number. You define the criteria that matter, decide how important each one is (its weight), score every supplier on each criterion, and the model rolls those up into a single comparable total.

The formula

For each supplier, the weighted score is the weight-share of every criterion multiplied by that supplier's score on it, summed across all criteria:

Weighted score (0–10) = Σ ( weight%i × scorei ) ÷ 100

Because every score is on the same 1–10 scale and the weights sum to 100%, the result is itself on a 0–10 scale — multiply by 10 for a familiar 0–100 index. Each criterion's contribution is weight% × score ÷ 100, so you can see exactly which factors carried a supplier. Suppliers are then ranked from highest to lowest, and the gap to leader shows how far each one trails the top choice.

Why weights must sum to 100%

Weights express relative priority. If they don't total 100% the 0–10 scaling breaks and totals are no longer comparable. Use Auto-normalise (or the normalise button) to rescale weights proportionally to 100% without changing their ratios.

Critical-criterion (knock-out) flags

A high overall score can hide a fatal weakness — a cheap, fast supplier that fails compliance or is financially fragile. Mark such criteria as critical (🚩) and set a minimum. Any supplier scoring below that minimum on a critical criterion is flagged so it can be challenged or excluded regardless of its total.

Worked example

With weights Price 25%, Quality 25%, Delivery 20%, Service 15%, Financial 10%, Risk 5%, a supplier scoring 8/7/9/6/7/8 earns: (25×8 + 25×7 + 20×9 + 15×6 + 10×7 + 5×8) ÷ 100 = (200+175+180+90+70+40) ÷ 100 = 7.55 → a 75.5 index.

Frequently asked questions

How many criteria and suppliers can I compare?
You can compare up to 5 suppliers and add as many criteria as you need. The default six criteria — Price/Cost, Quality, Delivery/Lead time, Service/Responsiveness, Financial stability and Risk/Compliance — are the classic CPSM/CIPS set, but every name, weight and score is editable.
Should a lower price get a higher or lower score?
A higher score always means "better" on every criterion. So a more competitive or better-value price should be scored higher (e.g. 9), and an expensive quote lower (e.g. 4). Keeping all criteria direction-consistent (higher = better) is what lets the weighted sum work. For a like-for-like cost comparison, pair this with a total-cost-of-ownership or lifecycle-cost analysis first, then convert to a 1–10 score.
What if my weights don't add up to 100%?
The tool warns you and shows the running total. Choose "Auto-normalise to 100%" (or press the normalise button) to rescale all weights proportionally so they sum to exactly 100% — the ratios between criteria stay the same, so your priorities are preserved.
How do critical-criterion flags work?
Tap the 🚩 next to a criterion to mark it critical (Risk/Compliance and Financial stability are good candidates). Set the minimum score (default 5). Any supplier scoring below that minimum on a critical criterion is flagged in the ranking — a signal to investigate or disqualify it even if its overall score looks strong.
What does "gap to leader" mean?
It's the leader's weighted score minus each supplier's weighted score. A small gap means the decision is close (worth a tie-break on price or a second round); a large gap means a clear winner.
