What AS9100 Certification Costs a Small Shop, and How Long It Takes

The short answer on AS9100 cost

Plan on two kinds of money: what you pay the registrar, and what you spend inside the shop. The registrar side is the part you can quote. The internal side is the part that sinks budgets.

Amtivo, a US certification body, estimates initial AS9100 certification at $8,000 to $30,000 for small and midsize organizations, covering the audit and registration fees, and puts annual surveillance audits at $3,000 to $15,000. The Tennessee Manufacturing Extension Partnership at the University of Tennessee gives a similar registrar range of $8,000 to $25,000 for the initial audit and certificate. Both note that the number moves with company size, number of sites and the registrar you pick.

Neither figure includes consultant fees, the standard itself, calibration you may have been skipping, software, or the hours your people spend writing procedures and producing records. For a 10 to 40 person job shop, that internal time is often the largest line item.

AS9100 cost table

These are the figures we could tie to a published source. Where no reliable public number exists, we say so instead of guessing.

Ask every registrar to quote the full three-year cycle, not just year one. A cheap initial audit paired with expensive surveillance days is a common surprise.

What drives the registrar quote

The registrar quote is mostly audit days times a day rate, plus travel. Audit days are not picked out of the air.

• Headcount. The IAQG audit rules in AS9104/1 set a baseline audit duration from the number of employees in scope. More people, more days.
• Risk rating. Under the revised AS9101 and AS9104/1, the shop submits an Organization Certification Analysis Process (OCAP) report to the registrar 90 days before the audit. The registrar rates the shop high, medium or low risk, and that rating can shorten or lengthen audit time, according to NASA's Office of Safety and Mission Assurance.
• Design responsibility. If you only build to print, you can usually exclude design and development, which trims scope. If you own designs, expect more audit time.
• Sites. A second building or a satellite operation adds days and travel.
• Which standard. AS9100 is for organizations that make product. AS9120 covers distributors and AS9110 covers maintenance and repair. Amtivo's published ranges for AS9120 and AS9110 are lower than for AS9100, so pick the one that fits what you actually do.

The internal cost most shops underestimate

The registrar checks whether your system works. Building the system is on you, and AS9100 asks for more than a generic ISO 9001 manual.

Items that tend to eat time in a job shop:

• Configuration management, so the floor always runs the current drawing revision and the customer's flow-downs reach the traveler.
• First article inspection records, usually to AS9102 when the customer asks for it.
• Calibration with traceable records for every gage used to accept product.
• Counterfeit part prevention and foreign object damage (FOD) controls.
• Supplier control for your own outside processors: plating, heat treat, NDT.
• Risk management, on-time delivery and quality metrics, internal audits and a documented management review.

The registrar will also want to see the system running, with records, before the certification audit. That means a few months of operating to your own procedures, at least one full internal audit cycle, and a management review on file.

How long AS9100 takes

The University of Tennessee TMEP says most manufacturers it works with take 12 to 24 months, and 18 to 24 months when starting without a quality management system. Shops that already hold ISO 9001 move faster because the base system exists.

1. Gap analysis. Compare what you do today against AS9100 and your customers' quality clauses.
2. Process mapping and documentation. Write procedures that match how work really moves through the shop.
3. Run the system. Generate records: inspection, calibration, training, corrective action.
4. Internal audit and management review. Find your own nonconformances first.
5. Stage 1 audit. The registrar reviews documentation and readiness.
6. Stage 2 audit. The certification audit on the floor.
7. Close findings. Corrective actions are accepted, the certificate is issued, and the shop appears in the IAQG OASIS database.

The three-year cycle and what it costs to keep

An AS9100 certificate runs three years. Surveillance audits come in years one and two, then a full recertification audit in year three. Budget for all three every cycle.

NASA's safety and mission assurance office describes a Performance Based Surveillance and Recertification process in the newer audit rules. Shops that qualify, with a low or medium risk rating, annual self-audits of all QMS elements and no certificate suspension in the prior six years, can have surveillance sampling cut from 50 percent to 33 percent of QMS elements per year, as long as everything is audited within 48 months. That can trim surveillance days once your system is stable.

Ways to keep AS9100 cost down without cutting corners

• Get three quotes from accredited certification bodies, and compare quoted audit days, not just the total.
• Scope honestly. Exclude design if you do not do design. Do not include a second site that does no aerospace work.
• Use what you have. If you hold ISO 9001, build on it rather than starting a new manual.
• Buy the consultant's time, not their binder. Generic manuals fail audits when the floor does something else.
• Fix calibration and traceability early. They are cheap to fix before Stage 2 and expensive as findings.

Also read your customers' purchase order quality clauses before you start. Some buyers require AS9100 certification outright. Others accept ISO 9001 with specific flow-downs, source inspection, or a first article. Knowing which customers need what tells you whether AS9100 is a this-year project. Our approved supplier list guide covers how buyers use certifications when they qualify a shop.

A revision is coming: IA9100

The current standard is AS9100 Rev D. IAQG is developing the next revision, which will carry the new IA9100 name. NASA's Office of Safety and Mission Assurance reported that the publication estimate moved to the fourth quarter of 2026 to line up with the ISO 9001 revision.

If you are starting now, ask your registrar how it plans to handle the transition and whether certifying to Rev D first means a transition audit soon after. It should not stop you from starting, since the core system carries over, but it belongs in the three-year budget.

Put your AS9100 status in front of buyers

Whether you are certified, mid-project, or running ISO 9001 today, list it when you join Aerospace Sourcing free. We match buyer requests to suppliers based on capability and the requirements each job flows down, so a buyer that accepts ISO 9001 plus a first article can still reach a shop that is not certified yet. We review every signup and contact you when work fits. We do not promise a volume of RFQs.

If paperwork is your bottleneck, the signup also offers early access to our quality paperwork software for first article, certificate of conformance and traceability records. For the bigger picture, start with the aerospace supplier guide, check the supplier readiness checklist, and if you run special processes, read about Nadcap accreditation.
