Supplier due diligence is the detailed, evidence-based verification of a prospective supplier before you contract with them. It confirms the company legally exists, is financially sound, is owned and controlled by who it claims, is free of sanctions and serious adverse media, and has the operational capacity to deliver. The output is a documented assessment you can rely on and defend.

What it covers

Vetting vs due diligence

The two terms overlap. "Vetting" describes the broad act of checking a supplier is suitable; "due diligence" describes the detailed verification that sits underneath it. In practice a good supplier vetting engagement is due diligence — the label matters less than whether the checks are done against primary sources.

When you need it

Due diligence earns its cost when the order is significant, the supplier is new or overseas, money crosses borders, or the relationship will be ongoing. In regulated settings it can also be a formal requirement. When the stakes are low and the supplier is well known, a lighter check may be enough.
