Vendor Lead Time Scorecard automatically tracks the gap between a vendor's promised delivery date and the actual goods receipt date for every purchase order line. Each receipt generates a scorecard entry that calculates delay days and an on-time flag, then rolls up into a vendor-level summary with a 0–100 reliability score and a letter grade (A–F). Purchasing managers can drill into individual delivery entries to spot chronic late suppliers, while supply chain analysts use the aggregated kanban view for at-a-glance performance comparison across the entire supplier base. Overdue pending entries are flagged automatically so buyers can chase outstanding deliveries before they impact production schedules.
