GTBuy: Building Long-Term Seller Performance Logs in Your Spreadsheet

2026-01-04

For businesses leveraging platforms like GTBuy, maintaining a systematic record of seller performance is crucial for informed, long-term sourcing decisions. A well-structured spreadsheet, powered by conditional formatting, can transform raw data into an actionable performance dashboard. Here’s how to build one.

Step 1: Establish Your Core Data Structure

Create a spreadsheet with the following core columns for each order or periodic assessment:

  • Seller ID/Name
  • Order Date
  • Delivery Score
  • QC Score
  • Overall Performance Score
  • Comments/Notes

Step 2: Calculate Long-Term Averages

Dedicate a separate "Seller Summary"AVERAGEIFS

Example: =AVERAGEIFS(RawData!C:C, RawData!A:A, Summary!A2) // Avg Delivery Score for Seller in A2

Step 3: Implement Conditional Formatting for Instant Insights

This is where your log becomes visual. Apply rules to the average score columns

For Highlighting Top Performers:

  • Green Gradient (Data Bars):
  • Top 10% Rule (Green Fill):

For Risk Identification:

  • Red Highlight (Cell Fill):Delivery Score average is below a threshold
  • Yellow Flag (Icon Set):QC Score average is between 6 and 7, indicating quality needs monitoring.

Step 4: Maintain & Review

Consistently log new transaction data. The conditional formatting will update dynamically, providing a real-time visual map of your supply chain health. Periodically review sellers flagged in yellow or red to make data-driven decisions on coaching or sourcing.

Conclusion

By moving beyond simple record-keeping to a dynamic, formatted performance log, you empower your GTBuy strategy with clarity. Conditional formatting turns numbers into narratives, highlighting reliable partners and signaling where attention is needed, ultimately fostering stronger, more resilient supplier relationships.
