Why choose us

Why work with us

A good standard should make the actual work easier — not just earn a paper for the wall.

  • We speak plain language, not clause numbers

    Every technical term gets explained first. Ask twice — no one minds.

  • Auditors matched to your business

    Our team covers both manufacturing and services, so you get observations you can use the very next day.

  • Straight talk on price and timing, from day one

    Our quotation itemises what drives the price, how many audit days, and what costs follow — no surprise invoices later.

  • Right next to the Eastern Seaboard industrial zone

    Based in Sriracha: quick to sites across Chonburi and Rayong, and especially at home in automotive and manufacturing.

How it works

The certification journey in five steps

Every standard follows the same five steps — only the audit content differs.

  1. Talk to us and define the scope

    Tell us what you do, how many sites and people. We estimate the audit days and send your quotation.

  2. Prepare your documented system

    You write down how the work is really done — yourself or with a consultant. We can't do it for you: auditors must never audit their own work.

  3. Stage 1 audit

    The auditor checks documentation readiness and scope. The result is a readiness report: what to close before the main audit.

  4. Stage 2 audit

    On site: talking to your people, checking evidence. Any findings come with a deadline to fix.

  5. Certificate and surveillance

    Close all findings and receive a certificate valid three years, with an annual surveillance audit.

Timelines and details vary with the size and complexity of each organisation.
