AS9100 certification cost is not a single sticker price, it is the sum of several moving parts: the certification body audit fees, your company size and number of sites, how mature your current quality system is, whether you run special processes, the level of consulting help you use, and ongoing surveillance audits. Each of those levers pushes the total up or down.
In the systems we build for aerospace and manufacturing clients, the biggest surprises are almost never the registrar invoice. They come from the internal effort to close gaps before the auditor ever arrives. Understanding the drivers early lets you plan a budget you can actually defend to leadership.
Key takeaways
- AS9100 certification cost is driven by audit fees, company size, current gap maturity, special processes, consulting, and surveillance audits.
- AS9100 usually costs a bit more than ISO 9001 because it layers aerospace requirements on top of the same base standard.
- Certification is not one payment. A three year cycle adds annual surveillance audits after your initial registration.
- The fastest way to control cost is to close gaps and train your team before the Stage 1 audit.
What drives AS9100 certification cost
Six factors do most of the work when it comes to your AS9100 certification cost. Here is how each one moves the number.
- Certification body audit fees. An accredited registrar charges for auditor time across a Stage 1 readiness review and a Stage 2 certification audit. Fees are priced in auditor days, so anything that adds days to the audit adds cost.
- Company size and number of sites. More employees, more shifts, and more physical locations mean more audit days and more of your own people pulled into preparation. A single small shop audits faster than a multi site manufacturer.
- Current gap and QMS maturity. A company already certified to ISO 9001 starts far ahead of one with no documented system. The wider the gap between where you are and what AS9100 expects, the more time and money it takes to close.
- Special processes and Nadcap. Heat treating, welding, non destructive testing, and chemical processing often trigger Nadcap accreditation, which is a separate program with its own audits and fees on top of AS9100.
- Consulting support. Outside help for gap analysis, documentation, training, and internal audits is an added line item, but it usually shortens the timeline and reduces the risk of a failed audit.
- Surveillance audits. Certification runs on a three year cycle. After you pass, the registrar returns for annual surveillance audits, so ongoing cost is part of the real total, not an afterthought.

Why AS9100 certification cost runs higher than ISO 9001
AS9100 is built on ISO 9001, then adds aerospace specific requirements: risk management, configuration management, counterfeit parts prevention, product safety, and first article inspection. Those additions expand the scope an auditor has to review and the evidence your team has to produce, which is why AS9100 certification cost typically lands above a comparable ISO 9001 project.
| Cost element | ISO 9001 | AS9100 |
|---|---|---|
| Base quality management system | Required | Required |
| Aerospace specific clauses | Not included | Added scope, more audit time |
| Special process and Nadcap exposure | Rare | Common for aerospace suppliers |
| Auditor qualification | General QMS auditor | Aerospace experienced auditor |

How long does it take to get AS9100 certified
Most first time projects run several months from kickoff to certificate, and timeline is tied directly to budget. A company with a mature quality system and a trained internal audit team can move quickly. A company starting from scratch spends more time writing procedures, running processes long enough to generate records, and correcting findings. The longer the runway, the more internal labor cost stacks up, which is why closing gaps efficiently protects both the schedule and the spend.
How do I get AS9100 certified
The path is predictable, and knowing the steps helps you forecast where the money goes.
- Run a gap analysis against the current AS9100 revision.
- Build or update documentation so it matches how you actually work.
- Train your team and put the processes into daily use.
- Generate records, then run internal audits and a management review.
- Pass the registrar Stage 1 and Stage 2 audits to earn the certificate.
Who needs AS9100 certification
AS9100 applies to organizations in the aviation, space, and defense supply chain: manufacturers, distributors, and service providers whose customers or primes require it. If a contract names AS9100 as a condition, certification stops being optional. That customer pressure is often what sets the deadline, and the deadline is what shapes how much you spend to get there on time.
The OQS AS9100 certification cost checklist
Before you request a quote from a registrar, work through these five items. They surface the hidden drivers that catch teams off guard.
- List every physical site and shift in scope, since audit days scale with them.
- Flag any special processes and confirm whether Nadcap applies, because that is a separate budget line.
- Score your current maturity honestly, from no system to ISO 9001 certified, to size the gap.
- Decide where internal labor ends and consulting begins, then price both, not just the registrar fee.
- Reserve budget for the full three year cycle, including surveillance audits, not only year one.
AS9100 is published by SAE International as part of its aerospace standards, and registrars audit against that document.
AS9100 certification cost FAQ
How often is an AS9100 audit? After certification, a registrar conducts surveillance audits on a regular cadence across the three year cycle, then a full recertification audit before the certificate expires.
How much do AS9100 auditors make? Auditor pay varies by experience and region, but from a buyer view what matters is that experienced aerospace auditors command higher day rates, which feeds into your certification body fees.
Can consulting lower my AS9100 certification cost? Consulting is an added expense, yet it often reduces total cost by shortening the timeline and lowering the risk of a failed audit and repeat visits.
What is the biggest hidden cost? Internal labor. The hours your team spends closing gaps and running the system usually outweigh the registrar invoice, so plan for it early. To scope your project, contact our team.
