How to Evaluate Seller Performance Using the VigorBuy Spreadsheet
Building a reliable supplier network is crucial for successful sourcing. The VigorBuy Spreadsheet provides a systematic approach to vendor evaluation, helping you make data-driven decisions and cultivate a trusted vendor list.
Key Metrics to Track for Seller Evaluation
1. Quality Control (QC) Approval Rates
Track the percentage of shipments that pass your quality inspections. Consistently high approval rates indicate reliable product quality.
- Calculate: (Number of QC-passed shipments / Total shipments inspected) × 100
- Goal: Identify suppliers maintaining 95%+ approval rates
- Action: Flag suppliers with repeated quality issues
2. Delivery Time Performance
Monitor actual vs. promised delivery times to assess reliability and planning accuracy.
- Track: Promised delivery date vs. Actual delivery date
- Calculate: Average delay days and on-time delivery rate
- Goal: Suppliers with consistent on-time delivery (90%+ rate)
3. Communication History & Responsiveness
Document communication quality, response times, and problem-solving effectiveness.
- Track: Response time to inquiries (hours/days)
- Note: Communication clarity and professionalism
- Record: Problem resolution effectiveness
