How to Vet a Supplier or Business Partner Before You Commit

Match the effort to the risk

Not every supplier needs a deep investigation, but every meaningful commitment deserves a basic check. A quick, repeatable process protects you from the most common problems — non-delivery, misrepresentation, or dealing with an entity that is not what it claims to be.

A proportionate vetting checklist

Before you sign or send a first payment:

• Confirm registration, legal name and active status in the relevant registry.
• Check ownership and how long the business has genuinely operated.
• Look for independent reviews, references and any public disputes.
• Verify bank and invoice details match the legal entity exactly.
• Start with a smaller order or milestone where possible.
• Record what you checked and when — a short diligence note.

Red flags worth pausing for

Reluctance to provide verifiable details, pressure to pay quickly or in full up front, payment to a different entity or personal account, and a track record that doesn't match the claims are all reasons to slow down and verify further before committing.

Documenting the decision

Keep a short record of your checks and why you proceeded. It supports good governance and means that if the relationship is ever questioned, your decision is defensible. For significant partnerships, EZFIN can carry out structured due diligence and OSINT and deliver a clear briefing to inform the decision.
