An RFI is an exploratory tool, used to gather information before specifications or tendering. It is appropriate for obtaining indicative pricing (A), understanding the range of products/services (C), and confirming certifications like environmental or quality standards (D). RFQs, by contrast, request firm pricing based on defined specifications. RFIs are not used to renegotiate existing contracts (E) or agree payment terms (B). Responsible sourcing emphasises using RFIs to identify suppliers aligned with ethical, environmental, and operational expectations before moving to a formal competitive process.
