Supplier Reliability Index

The Supplier Reliability Index is a quarterly benchmarking tool that measures the overall reliability of supplier relationships based on key components, including on-time delivery, responsiveness, and price or quantity changes.

Powered by SourceDay’s proprietary PO lifecycle data from over 101,000 suppliers, the Supplier Reliability Index is designed to help manufacturers and distributors assess and predict supplier performance and supply chain risk. By consolidating critical indicators, it offers early warnings of potential disruptions and supports proactive supply chain management.
