ACBUY Spreadsheet: Automating Vendor Scoring with Weighted QC & Refund Performance
Transform subjective vendor evaluation into a data-driven, automated process for smarter sourcing decisions.
Manually evaluating vendors based on Quality Control (QC) failures and refund rates is time-consuming and prone to inconsistency. The ACBUY Spreadsheet
Why Automate Vendor Scoring?

Core Methodology: Defining the Weighted Score
The automation hinges on creating a composite score where QC and refund metrics are assigned different weights based on their business impact. A common practical model is a 70/30 split.
Example Weighting Structure
| Metric | Weight | Rationale |
|---|---|---|
| QC Failure Rate | 70% | QC issues directly impact customer satisfaction, lead to returns, and damage brand reputation. They are a leading indicator of problems. |
| Refund Rate (Due to Defects) | 30% | Refunds represent the ultimate financial cost and operational failure, but often stem from the QC issues captured above. |
Implementation Steps in Your Spreadsheet
Step 1: Data Foundation
Create the following columns for each vendor or order batch:
Vendor_IDTotal_Units_ReceivedUnits_Failed_QCTotal_Refunds_IssuedOrder_Value
Step 2: Calculate Core Metrics
Add calculated columns:
- QC_Fail_Rate:=Units_Failed_QC / Total_Units_Received
- Refund_Rate:=Total_Refunds_Issued / Total_Units_Received
Step 3: Normalize Scores (0-100 Scale)
To compare fairly, normalize each metric to a standard scale. Assuming lower rates are better:
QC_Score:=MAX(0, 100 - (QC_Fail_Rate * 10000))// Multiplier scales the decimal to a meaningful penalty.
Refund_Score:=MAX(0, 100 - (Refund_Rate * 5000))// Can use a different multiplier based on tolerance.
Step 4: Calculate Weighted Final Score
Apply the predetermined weights (e.g., 70%/30%) to compute the final vendor performance score automatically.
Final_Vendor_Score:=(QC_Score * 0.70) + (Refund_Score * 0.30)
