EastMallBuy Spreadsheet: Merging QC Data with Financial Records

2025-12-29

In the complex world of cross-border e-commerce, data often lives in isolated silos. Purchase costs are tracked in one place, while Quality Control (QC) results reside in another. The true performance of your sellers remains hidden. The EastMallBuy Spreadsheet

The Problem: Disconnected Data Streams

Typically, procurement teams manage:

  • Financial Records:
  • QC Data:

Analyzing these separately leads to incomplete conclusions. A seller might be cheap (good financials) but deliver poor quality (bad QC), or vice-versa. Without merging, you can't see the full picture.

The Solution: Creating a Unified Master Sheet

The core of the EastMallBuy approach is a single, master spreadsheet that connects every purchase order (PO) to both its cost and its quality outcome. Here's how to build it:

1. Define Your Key Linking Field

Create a unique identifier for each order, such as a Purchase Order NumberSupplier Batch Code. This will be the anchor for merging data.

2. Structure Your Data Tables

Financial Data Table QC Data Table
  • PO Number
  • Seller Name
  • Product SKU
  • Unit Cost
  • Quantity
  • Total Cost
  • Shipping Cost
  • PO Number
  • Inspection Date
  • AQL Result (Pass/Fail)
  • Critical Defects Found
  • Major Defect Rate %
  • Minor Defect Rate %
  • Overall Score

3. Merge Using Formulas

In your master sheet, use a VLOOKUP, XLOOKUP, or INDEX-MATCH

=XLOOKUP(A2, QC_Table[PO Number], QC_Table[Major Defect Rate %], "No QC Data")

This brings the defect rate for that specific order directly next to its cost information.

Visualizing Full Purchase Performance

With merged data, you can create powerful visualizations to compare sellers holistically:

Seller Scorecard Dashboard

Chart 1: Cost vs. Quality Scatter Plot

Plot sellers on a graph with "Average Unit Cost" on the X-axis and "Pass Rate" or "Defect Rate" on the Y-axis. Instantly identify:

  • Top-Left Quadrant (Low Cost, High Quality):
  • Bottom-Right Quadrant (High Cost, Low Quality):

Chart 2: Total Cost of Quality (TCOQ) by Seller

Create a calculated column: (Defect Rate % * Order Quantity * Unit Cost). This estimates the financial impact of poor quality. A bar chart ranking sellers by this "hidden cost" reveals who is truly expensive.
