Manually tracking and calculating seller performance is time-consuming and prone to error. For CNFANS users managing multiple suppliers or sellers, automating this process is key. By leveraging simple yet powerful spreadsheet formulas, you can create a self-updating dashboard that scores sellers based on critical metrics like ReliabilityRefund Ratios.
The Core Metrics: What to Track
Before building formulas, define your data columns. A basic tracking sheet should include:
- Seller Name/ID:
- Total Orders:
- Completed Orders:
- Refund Requests:
- Reliability Ratio:
- Refund Ratio:
- Performance Score:
- Total Orders:
Building the Auto-Calculating Formulas
Assume data starts in Row 2, with headers in Row 1. Columns are: A=Seller, B=Total Orders, C=Completed Orders, D=Refund Requests.
1. Calculate the Reliability Ratio
In cell E2=IFERROR(C2/B2, 0)
This divides Completed by Total Orders. The IFERROR function handles cases with zero total orders, returning 0 instead of an error. Format as a percentage.
2. Calculate the Refund Ratio
In cell F2=IFERROR(D2/B2, 0)
Similarly, this calculates the proportion of orders refunded. Format as a percentage.
3. Create the Composite Performance Score
The final score should weight reliability positively and refunds negatively. In cell G2=IFERROR(((E2 * 0.7) - (F2 * 0.3)) * 100, 0)
This formula assumes 70% weight for Reliability and 30% negative weight for Refund Ratio, scaling the result to a 0-100 scale (assuming ratios are decimals). Adjust weights based on your priorities.
4. Add a Rating Category (Optional)
To automatically assign a label like "Excellent," "Good," or "Poor," use a LOOKUP or nested IF. In cell H2:
=IF(G2>=85, "Excellent", IF(G2>=70, "Good", IF(G2>=50, "Fair", "Needs Review")))
This creates a clear, actionable tier for each seller.

Conclusion
By setting up these automated formulas in your CNFANS supplier spreadsheet, you transform a static log into a dynamic performance management tool. The moment you input new order and refund data, the Reliability and Refund Ratios will recalculate, instantly updating the Performance Score and rating. This not only saves hours of manual work but also provides an objective, real-time view of seller performance, enabling faster and better-informed sourcing decisions.
Tip: Once your template is built, simply copy the formulas down for each new seller you add to your list.
