Managing suppliers effectively is crucial for a successful importing business. By building a simple yet powerful Seller Rating System
Relying on memory or vague feelings about suppliers leads to inconsistent choices. A structured rating system helps you: In your main supplier or order tracking sheet, add these three key performance indicator (KPI) columns next to your supplier information. Rate each supplier or transaction on a consistent scale, for example, 1 (Poor) to 5 (Excellent). Add the three scoring columns (Reliability, Communication, QC Performance) to your main data sheet where you log each order or supplier entry. Define what constitutes a 3 vs. a 5 for each category. For example: A "5" in Reliability means shipping exactly on the confirmed date with 100% order accuracy.
Add a "Total Score"=SUM([Reliability Cell], [Communication Cell], [QC Cell]) Use your spreadsheet's sort and filter functions to rank suppliers by their Total Score. Create a separate summary sheet or pivot table to see average scores per supplier across all orders. Integrating this Seller Rating SystemReliability, Communication, and QC Performance, you empower yourself to build a more resilient, high-performing, and profitable supply chain. Start adding those columns today—your future self will thank you for the clarity and confidence it brings to your sourcing decisions.Why Create a Supplier Scoring System?
