In the world of international sourcing, your seller list is your most valuable asset. Consistent quality and reliable partnerships are key to a successful business. The ItaoBuy methodology emphasizes a systematic, data-driven approach to evaluating seller credibility. Maintaining a dedicated spreadsheet to track key performance indicators transforms guesswork into a reliable vetting process.
The Three Pillars of Seller Evaluation
An effective supplier spreadsheet should track these core metrics over time. Consistently high scores across all three areas signal a verified, top-tier supplier.
1. Quality Control (QC) Success Rate
This is the most critical metric. Record the percentage of orders that pass your quality checks upon inspection. Calculate it as: (Number of QC-Passed Orders / Total Orders Sampled) * 100.
