How to vet a new supplier before you commit

3/9/2026 · 5 min read

Vetting is not paperwork for its own sake. It is the cheapest way to find out, before you are dependent, whether a supplier can actually do the thing they have quoted for.

Check the claims that are verifiable

Certifications, registration numbers, insurance cover and named client work can all be confirmed independently. Ask for the certificate rather than the logo, and check the expiry date — lapsed certifications are more common than fake ones.

Ask for references that resemble you

A reference from a customer ten times your size, in another sector, tells you little. Ask for one similar in volume, geography and complexity, and ask that reference a specific question: what went wrong, and how was it handled?

Look at capacity, not just capability

A supplier can be excellent and still be full. Ask about current utilisation, who exactly would do your work, and what happens if their lead engineer or account manager leaves mid-project.

Start with a small, reversible order

Where the category allows it, place a small first order before the committing one. You learn more about a supplier from one real delivery — how they communicate when something slips — than from any amount of due diligence.

Use the record the platform already keeps

Verified listings on Quotendra record certifications, headquarters, team size, founding year and measured response time, and reviews come only from buyers with completed requests. It is not a substitute for your own checks, but it tells you quickly which suppliers are worth spending the checks on.
