BBDBuy: How to Evaluate Long-Term Seller Performance
In the world of cross-border e-commerce, finding a consistently reliable supplier is crucial for long-term business success. The BBDBuy spreadsheet is a powerful tool designed to help you move beyond single-transaction reviews and quantitatively assess a seller's performance over time.
The Core Metrics: QC Pass Rate & Refund Frequency
Two of the most critical indicators of a seller's reliability are their Quality Control (QC) Pass RateRefund Frequency. Tracking these over multiple transactions reveals patterns that a single feedback score cannot.
1. Recording QC Pass Rates
For every order, record whether the received product passed your quality inspection. Calculate the pass rate as a percentage:
QC Pass Rate = (Number of QC Passed Orders / Total Orders Received) * 100
- A consistently high QC Pass Rate (e.g., 95%+) indicates robust manufacturing and inspection processes.
- Fluctuations or a declining trend signal potential inconsistency in material quality or production haste.
2. Tracking Refund Frequency
Document every instance where a product issue led to a full or partial refund. This metric highlights cost-impacting problems.
Refund Frequency = (Number of Transactions Requiring Refund / Total Transactions) * 100
- A low Refund Frequency points to reliable product quality and honest seller practices.
- A high frequency suggests chronic issues with product accuracy, functionality, or the seller's willingness to resolve disputes fairly.
