BBDBuy: Evaluating Long-Term Seller Performance for Smarter Purchases-HAREBUY offer better prices, fewer restrictions, and top-rated finds via spreadsheet and rep communities like Reddit, Telegram, and Discord.**

Inconsistent seller quality is a major risk in B2B and wholesale sourcing. The BBDBuy Long-Term Seller Performance Spreadsheet

The Core Metrics: QC Pass Rate & Refund Frequency

Two metrics form the foundation of long-term seller evaluation:

Quality Control (QC) Pass Rate (%): The percentage of units from a seller that meet your specifications upon inspection. A high, consistent rate indicates reliable manufacturing quality.

Refund Frequency (per shipment or value): How often issues necessitate a partial or full refund. This is a direct indicator of problem severity and seller accountability.

How to Structure Your BBDBuy Spreadsheet

Create a dedicated sheet for each seller. Record the following columns for every transaction:

Order Date PO # / Item Quantity QC Pass Rate Defects Noted Refund Issued? (Y/N) Refund Amount Communication Score (1-5)

2023-10-15 SKU-A100 500 98% Minor packaging flaws N $0 5

2024-01-22 SKU-A100 500 95% 5% color variance Y 5% of order 4

Analyzing the Data: Identifying True Partners

Use quarterly or bi-annual analysis to spot trends:

Calculate Averages: Determine the mean QC Pass Rate and the percentage of transactions requiring a refund.

Track Trajectory: Is quality improving, declining, or stable? A seller with a gradually improving pass rate
Correlate Metrics: Does a dip in QC correlate with a spike in refunds? If not, the seller might be covering issues without true quality fixes.

Benchmark: Compare sellers of similar products. This highlights who genuinely outperforms the market.

The Outcome: Reduced Risk, Predictable Quality

By consistently logging and reviewing this data in your BBDBuy spreadsheet, you transform subjective impression into objective insight. You will be able to:

Reward top performers
Have evidence-based negotiations
Preemptively phase out inconsistent sellers
Make sourcing decisions based on long-term reliability, not just lowest price.

This disciplined approach turns your supplier list into a strategic asset, ensuring your supply chain is built on verified trust and performance.
