Structuring Your BBDBuy Performance Spreadsheet

From Data to Action: Identifying Trends
Regularly review your spreadsheet to calculate trends and make informed decisions:
Calculate Quarterly/Yearly Averages
Determine the seller's aggregate QC Pass Rate and Refund Frequency over set periods. Is performance improving, stable, or deteriorating?
Correlate Issues with Product Types
Note if problems cluster around specific items. This helps distinguish a seller-wide problem from an issue with a particular product line.
Evaluate Resolution Behavior
A seller who consistently takes responsibility and offers fair, swift resolutions is often more valuable long-term than a seller with minor hiccups but perfect initial quality.
