ACBUY Spreadsheet: Automating Vendor Scoring Based on QC and Refunds
A guide to assigning weighted performance scores automatically for superior, data-driven vendor evaluation.
The Challenge of Manual Vendor Evaluation
For businesses relying on multiple suppliers, manual vendor assessment is a time-consuming and often inconsistent process. Evaluating each vendor based on Quality Control (QC) pass ratesrefund/issue rates
The ACBUY Spreadsheet solves this by introducing an automated, weighted scoring model that turns raw performance metrics into actionable insights.
Core Concepts: QC Score and Refund Score
The automation is built on two foundational metrics, which can be easily tracked per vendor in your spreadsheet:
- QC Score (%):95% QC Score).
- Refund Score (%):not100% - Refund Rate. (e.g., a 4% refund rate = a 96% Refund Score).
Building the Automated Weighted Score
The power of the ACBUY method lies in combining these scores with your business priorities. Not all metrics are equally important. Here is the step-by-step automation logic you can implement using standard spreadsheet formulas:
Step 1: Define Your Weights
Assign weight percentages that reflect your strategic focus. For example:
- Quality Weight:
- Refund Weight:
Note: The sum of weights must equal 100%.
Step 2: The Automated Calculation
The formula for each vendor's Total Performance Score
Example Calculation:92% QC Score88% Refund Score. Total Score = (92 * 0.70) + (88 * 0.30) = 64.4 + 26.4 = 90.8 This single, weighted score allows for clear, apples-to-apples comparison across all vendors.
Visualizing Results for Instant Insight
Automation extends beyond calculation. Use your spreadsheet's conditional formatting and charting tools to:

Benefits of the ACBUY Automated System
Objectivity & Consistency
Removes personal bias and ensures every vendor is judged by the exact same criteria, month after month.
Efficiency & Scalability
Scores update automatically as new QC or refund data is entered. Evaluating 10 or 100 vendors takes the same minimal effort.
Strategic Decision-Making
Clear scores empower data-driven decisions on allocating orders, negotiating contracts, and conducting vendor improvement talks.
Proactive Risk Management
Automated alerts for falling scores allow you to address supply chain issues before they significantly impact your business.
