EastMallBuy Spreadsheet: Merging QC Data & Financial Records for Smarter Insights
Combine cost details with QC results to visualize your full purchase performance across different sellers.
For e-commerce businesses and global sourcing managers, data often lives in isolated silos. Financial records track costs, fees, and shipping, while Quality Control (QC) reports assess product integrity. The real power lies in merging these datasets. The EastMallBuy Spreadsheet methodology provides a framework to combine QC data with financial records, transforming raw numbers into a clear visualization of your true purchase performance per seller.
Why Merge QC and Financial Data?
Looking at cost or quality alone gives an incomplete picture. A cheap supplier with high defect rates is ultimately costly, while a premium supplier with flawless quality might offer the best total value. Merging data allows you to:
- Calculate True Cost-Per-Good-Unit:
- Score and Rank Sellers Holistically:
- Identify Hidden Losses:
- Make Data-Driven Sourcing Decisions:
- Score and Rank Sellers Holistically:
How to Merge Data in Your EastMallBuy Spreadsheet
Step 1: Establish Your Core Financial Sheet
Create a sheet named "Financials"
Column Data Example Seller Name Supplier A, Supplier B PO Number PO-2023-001 Product SKU EMB-WIDGET-01 Unit Cost $5.00 Quantity Ordered 1000 Total Order Cost $5,000 Shipping & Fees $300 Landed Cost Per Unit =($5000+$300)/1000 = $5.30
Step 2: Integrate QC Data Sheet
Create a separate but linkable sheet named "QC_Results". Key columns should include:
- PO Number
- Inspection Date
- Sample Size
- Defect CountMajor/Minor Defect Breakdown
- QC Pass/Fail Status
- Defect Rate
- Notes
Step 3: The Merge: Create a Master Performance Dashboard
This is the core of the EastMallBuy method. Create a "Seller_Performance"VLOOKUP, XLOOKUP, or INDEX/MATCH) to pull data from both source sheets using the PO Number as a unique key.
Your merged columns will look like this:
| Seller | PO Value | Landed Cost/Unit | QC Defect Rate | Adjusted Cost Per Unit* | Performance Score |
|---|---|---|---|---|---|
| Supplier A | $5,300 | $5.30 | 2% | $5.41 | Excellent |
| Supplier B | $4,800 | $4.80 | 12% | $5.45 | Poor |
*Adjusted Cost Per Uniteffective cost
Step 4: Visualize Performance
