Manually tracking supplier performance is time-consuming. By leveraging built-in spreadsheet formulas, you can create a dynamic, auto-calculating scorecard for reliability and refunds. This guide outlines the core system.
1. Structuring Your Data
Start with a clean log. Assume columns for:
- Seller ID (Column A)
- Orders Fulfilled On Time (Column B)
- Total Orders (Column C)
- Refund Amount (Column D)
- Total Order Value (Column E)
2. Calculating Core Ratios
Insert two new columns: Reliability ScoreRefund Ratio.
Reliability Score Formula (Column F):
=IF(C2>0, (B2/C2)*100, "N/A")This calculates the percentage of orders fulfilled on time.
Refund Ratio Formula (Column G):
=IF(E2>0, (D2/E2), "N/A")This calculates the fraction of value refunded. Lower is better.
3. Creating the Composite Performance Score
Add a final Performance Score
Here, =IFERROR((F2*0.7) + ((1-G2)*100*0.3), "Incomplete Data")(1-G2)*100
4. Automating Tiers & Alerts
Use For visual alerts, use Conditional Formatting
IFSVLOOKUP
=IF(H2>=90, "Excellent", IF(H2>=75, "Good", IF(H2>=60, "Watch", "Review Needed")))
