Your aerospace ERP stops where the ITAR spreadsheet begins: problems and solutions
If your Simi Valley shop runs NetSuite or Odoo for accounting but tracks lot numbers, country-of-origin, and ITAR export status in a side spreadsheet, you do not have an ERP (Enterprise Resource Planning) problem, you have a traceability gap that a custom build closes. Expect $95k to $175k and 5 to 8 months for an ERP that carries part genealogy and export-control flags through every transaction.
Businesses in Simi Valley run into very specific operational problems. Across aerospace and defense, biotech and pharmaceuticals, small manufacturing, the same Defense and aerospace subcontractors handle compliance-heavy documentation and part traceability in spreadsheets, making it slow and error-prone to satisfy ITAR and quality audit requirements. keeps surfacing, manual workflows that do not scale, disconnected tools that leak data, and software that fights the team instead of helping it. The right custom build closes those gaps directly, turning the daily friction Simi Valley companies feel into systems that just work, so the team spends time on customers instead of workarounds.
NetSuite, SAP Business One, and Odoo all assume your compliance burden is financial. For a Wood Ranch defense subcontractor it is physical and legal: which serial number came from which heat lot, which operator signed off, whether a part is ITAR-controlled and therefore cannot ship to a foreign-national employee on the floor. None of that fits a standard item master, so it ends up in a parallel Excel file nobody trusts during a customer source inspection.
The break point is the audit. When a prime like Boeing or a DCMA rep asks you to reconstruct the genealogy of a flight-critical part shipped 18 months ago, the spreadsheet either does not have it or has three conflicting versions. Off-the-shelf ERP will not enforce that the record exists at the moment the part is received, which is the only place enforcement matters.
- You ship ITAR-controlled parts and reconcile traceability in spreadsheets
- A prime contractor or DCMA audit forced a multi-day manual genealogy rebuild
- Your shop-floor inventory and accounting inventory regularly disagree
- You run more than a few dozen controlled part numbers across multiple contracts
- You are a pure professional-services shop with no physical part traceability
- Your compliance burden is financial only and NetSuite or SAP already covers it
- You have fewer than a handful of controlled parts and the manual log is genuinely fine
- You need to be live in under three months and can accept the spreadsheet gap for now
- Part genealogy reconstructed in seconds for any serial number during a DCMA or prime-contractor audit
- ITAR and EAR classification enforced at receiving, blocking ineligible handling before it happens
- AS9100 nonconformance, MRB dispositions, and CAPA records tied to the exact part and operation
- First-article and certificate-of-conformance data generated from system records, not retyped from PDFs
- One source of truth so the shop floor count and the financial inventory finally agree
- You take on long-term ownership: export-control rules change and someone has to keep the logic current
- Migrating dirty spreadsheet history is genuinely painful and often costs more than the build does
- A custom ERP is overkill if you run fewer than a handful of controlled part numbers a quarter
- It will surface data discrepancies you have been quietly living with, which is uncomfortable at first
The honest cost picture for Simi Valley
| Project scope | Typical cost | Timeline |
|---|---|---|
| Core ERP plus lot and serial traceability | $95k to $135k | 5 to 6 months |
| Add ITAR enforcement and AS9100 nonconformance workflow | $135k to $160k | 6 to 7 months |
| Full part genealogy plus FAI and audit-query automation | $160k to $175k | 7 to 8 months |
Feature priorities for Simi Valley teams
Simi Valley ERP: the full scope
The engagements Simi Valley teams bring us most often: ERP API integration, ERP implementation, ERP integration, NetSuite customization, SAP integration, Odoo development and Microsoft Dynamics 365.
Exactly what you get
You get an ERP where a part cannot exist in the system without its lot, supplier cert, and export classification, and cannot move to a work order without an eligible operator signing it. When a Simi Valley prime asks for the full genealogy of serial 00428, you run one query and hand them a clean record instead of cross-checking three spreadsheets. Nonconformances, MRB dispositions, and first-article data all hang off the same record, so your AS9100 surveillance audit becomes a demonstration rather than a fire drill. It connects to your accounting, your inventory management software, and your business intelligence dashboards so the numbers stop disagreeing.
How to choose a developer in Simi Valley
Pick a team that has shipped systems for a regulated manufacturer, not just a generic ERP shop. Ask them to walk through how they enforced export-control rules at the data layer on a past build, and listen for whether they understand that the enforcement has to happen at receiving. A local or US-based team matters here because ITAR data residency is not negotiable. Have them describe a traceability migration they have done and what went wrong, the honest answer tells you whether they have actually lived through one.
Timeline: what happens, and when
- !They have never heard of ITAR or AS9100, ask whether they have built export-controlled systems before
- !They propose hosting on infrastructure outside the US, ask specifically about data residency
- !They treat traceability as an optional reporting layer, ask how they enforce it at receiving
- !They quote a fixed price before seeing your part-numbering and lot scheme, ask for a discovery phase first
- !No plan for keeping export classifications current, ask who owns the rules after launch
If erp is on the roadmap, internal tools, shopify, inventory management usually follow within the year. Budget them as one conversation.

Frequently asked questions
Can NetSuite or SAP handle ITAR traceability?
They handle the financial side well, but neither enforces export classification or part genealogy at receiving out of the box. Most Simi Valley shops bolt a spreadsheet onto NetSuite, which is exactly the gap a custom ERP closes.
How long before an aerospace subcontractor sees payback?
The payback is concentrated at audit time. Shops that were spending two days rebuilding genealogy for a single DCMA request typically recover the cost within the first few audit cycles plus the inventory accuracy gains.
Do we have to migrate all our spreadsheet history?
No, and you usually should not. Migrate active and recently shipped parts cleanly, and archive the rest read-only. Trying to perfectly reconcile years of inconsistent spreadsheets is where budgets disappear.
Can it integrate with our prime contractor's portal?
Yes. Certificate-of-conformance and first-article data generated by the system can be pushed to prime portals, replacing the manual re-keying that introduces errors today.
Is custom ERP worth it for a small Simi Valley shop?
If you run controlled parts and audits hurt, yes, even at small volume. If your compliance is purely financial, an off-the-shelf ERP plus good bookkeeping is the smarter spend.
