For every savvy importer or e-commerce seller, the true picture of a purchase isn't just in the cost or the quality alone—it's in the combination of both. The EastMallBuy Spreadsheet
Traditionally, cost spreadsheets and QC reports live in separate worlds. Finance tracks unit costs, shipping, and tariffs. QC teams log defect rates, measurement failures, and packaging issues. This disconnect makes it impossible to answer critical questions: Is the cheaper seller actually more costly due to high defect rates? Does a premium-priced supplier justify their cost with flawless quality?
Follow this process within your master EastMallBuy spreadsheet (using tools like Google Sheets or Microsoft Excel) to create a unified dashboard. Create a sheet named The Disconnect Problem: Why Merging Data is Crucial
How to Merge QC Data and Financial Records: A Step-by-Step Guide
Step 1: Structure Your Financial Data Sheet
Costs. Each row should represent a Purchase Order (PO) or product line, with columns for:
Step 2: Structure Your QC Results Sheet
Create a sheet named QC_Results. Each row should correspond to an inspected batch, with columns such as:
Step 3: Create a Unified Master Sheet with VLOOKUP or XLOOKUP
This is the core of the merge. Create a Seller_Performance
Example Formula=XLOOKUP(A2, QC_Results!A:A, QC_Results!H:H, "No QC Data")
This would look for the Seller Name in cell A2 within the QC sheet and return the Defect Rate. Repeat to pull in Pass/Fail Status, Key Issues, etc.
Step 4: Calculate True Cost & Performance Metrics
Now, create powerful calculated columns that tell the full story:
- Adjusted Cost Per Unit:= (Landed Cost / (Total Quantity * (1 - Defect Rate))). This inflates your effective cost based on defective, unsellable units.
- Performance Score:
- Quality-Cost Ratio:
