Sync QC, Purchase, and Shipment Data for Accurate Stock Visibility

In the fast-paced world of e-commerce and supply chain management, maintaining accurate inventory visibility is not just an advantage—it's a necessity. The CNFANS Spreadsheet

The Challenge of Disconnected Data

Traditional inventory management often suffers from data silos. Purchase orders are in one file, QC inspection results in another, and shipment logs somewhere else entirely. This disconnect leads to:

  • Inaccurate stock counts, causing overselling or stockouts.
  • Delayed response
  • Poor decision-making

The CNFANS Spreadsheet directly addresses this by creating a single source of truth.

How to Maintain Real-Time Tracking with CNFANS

1. Centralized Data Hub Structure

Design your CNFANS spreadsheet with dedicated, interlinked tabs for each core function:

Sheet Tab Data Ingress Key Fields
Master SKU List Product Database SKU, Product Name, Reorder Point, Target Stock
Purchase Orders (PO) Procurement Team/Vendor Info PO #, SKU, Quantity Ordered, Date Ordered, Estimated Arrival
QC Inspection Quality Control Team/Reports PO #, SKU, Quantity Passed, Quantity Failed, Defect Details, Inspection Date
Shipment & Receiving Logistics/3PL/Warehouse SKU, Quantity Received, Shipment ID, Actual Arrival Date, Location
Live Inventory Dashboard Automated Calculations Real-time Stock Level, Available to Sell, On-Order Quantity, Stock Alert Status

2. Establishing the Data Sync Logic

The real-time magic happens through formulas and rules that connect the tabs. For example:

  • Stock Calculation:"Live Inventory"Opening Balance + SUMIF(Received) - Sales - SUMIF(QC_Failed)
  • QC Sync:
  • Purchase Sync:

3. Maintaining Real-Time Accuracy

Implementation is key. Follow these practices:

  • Mandatory Data Entry Protocols:immediately
  • Automated Alerts:
  • Regular Reconciliation:
  • Cloud-Based Access:

The Power of Synchronized Visibility

Eliminate Overselling

Your sales channels can pull available stock from the live dashboard, ensuring you only sell what you truly have.

Proactive QC Management

Spot defective batches early. Link QC failure data to specific vendors for improved sourcing decisions.

Streamlined Procurement

Accurate "On-Hand" and "On-Order" views prevent duplicate ordering and help optimize reorder timing.

Enhanced Decision Making

Make faster, data-driven decisions on promotions, purchasing, and warehouse management with a complete picture.
