Buying an ERP for an aerospace and defence manufacturing business is not the same as buying accounting software with a production module bolted on. The wrong platform will quietly cost you a NADCAP finding, a delayed First Article Inspection, an export-control breach, or a programme review where you cannot show earned value. The right platform becomes the single source of truth that a DGAQA auditor, a Tier-1 customer and your own shop floor can all trust. This aerospace ERP buying checklist is written to be used, not just read. Print it, score every shortlisted vendor against it, and treat any weak column as a risk to be priced or walked away from.
If you are building a shortlist, start with our aerospace and defence ERP platform and score it against the checklist below.
We have grouped the checklist into five decision blocks that mirror how a serious evaluation actually unfolds: functional fit, compliance and security, technology, vendor and implementation, and commercial. Each row gives you a one-line reason the item matters so the person doing the scoring understands what is at stake, not just what to tick. If you want the working copy, there is a downloadable version linked near the end of this guide that you can share with your evaluation committee.
Score every item simply. Use a three-point scale: Yes (demonstrated live), Partial (roadmap or workaround), and No. A single No in the compliance block should stop the deal until it is resolved. Several Partials in the functional block are normal and negotiable. The point of a checklist is not to find a perfect product; it is to make the gaps visible before you sign.
Block 1: Functional fit
Functional fit is where most demos look identical and most implementations later diverge. Insist on seeing each capability run against your own part number, your own bill of materials and your own routing, not a polished sample dataset. The questions below separate an ERP that was built for discrete engineering-heavy manufacturing from one that was built for distribution and dressed up.
Engineering, BOM and configuration
| Checklist item | Why it matters | Score |
|---|---|---|
| Multi-level, revision-controlled BOM with effectivity dates | Aerospace parts change by revision and by serial; the ERP must know which BOM was valid when a unit was built. | Yes / Partial / No |
| Engineering change management (ECN/ECO) with approval workflow | Uncontrolled changes are an AS9100 non-conformance waiting to happen. | Yes / Partial / No |
| Configuration and as-built versus as-designed tracking | Programmes need to prove the exact configuration delivered, part by part. | Yes / Partial / No |
| Alternate and substitute part control with approval | Substitutions in defence work must be governed, not left to a buyer. | Yes / Partial / No |
Planning, MRP and shop floor
- MRP that respects long lead times, minimum order quantities and lot sizing. Why it matters: aerospace lead times run in months, so netting logic that assumes weekly replenishment will starve the line.
- Finite capacity and work-centre scheduling. Why it matters: a single five-axis machine is often the constraint that decides your whole delivery plan.
- Work-order routing with operation-level booking and time capture. Why it matters: without operation-level data you cannot cost a job or prove effort on a cost-plus programme.
- Rework, scrap and non-conformance handling inside the work order. Why it matters: scrap in aerospace is expensive and must be traceable to a cause and a disposition.
Quality: AS9100, AS9102 FAI and NADCAP
Quality is not a bolt-on module in this sector; it is woven through every transaction. A credible platform links inspection, certificates and process control directly to the material and the work order so that evidence is a by-product of doing the work rather than a scramble before an audit.
- AS9100-aligned quality management with document and record control. Why it matters: your certification body expects controlled records, not spreadsheets emailed around.
- First Article Inspection to AS9102 with the three standard forms. Why it matters: a customer can reject a shipment purely because the FAI package is incomplete.
- NADCAP special-process control for heat treat, NDT, chemical processing and coatings. Why it matters: an unapproved or lapsed special process invalidates the part regardless of how well it was machined.
- Certificate of conformance and material certification capture. Why it matters: you must produce mill certs and CoCs on demand for every airworthy part.
- Calibration and gauge control with due-date alerts. Why it matters: an out-of-calibration gauge can retroactively cast doubt on months of inspection results.
Traceability and MRO
- Full serial and lot genealogy, forward and backward. Why it matters: when a defect is found you must locate every affected unit within hours, not weeks.
- Life-limited parts and cycle or hours tracking. Why it matters: airworthiness depends on retiring components before they exceed their approved life.
- MRO and repair-order workflows separate from new-build. Why it matters: teardown, inspect, repair and return-to-service follow a different logic than manufacturing.
- Counterfeit-part and DPAS or priority-rating awareness where relevant. Why it matters: supply-chain integrity is a contractual and safety obligation.
Programme management, procurement and finance
- Programme and project structures with earned value management. Why it matters: defence customers review cost and schedule performance in EVM terms, and you must report in the same language.
- Milestone and progress billing tied to programme events. Why it matters: cash flow on long programmes depends on billing at the right gates.
- Procurement with approved vendor lists, source approval and flow-down of quality clauses. Why it matters: your customers hold you responsible for controlling your own supply chain.
- GST-compliant invoicing with e-invoice and e-way bill generation. Why it matters: Indian tax rules require IRN and e-way documents that must reconcile with your dispatches.
Block 2: Compliance and security
This block is where a No should stop the deal. In aerospace and defence the cost of a compliance gap is not a support ticket; it is a lost approval, a blocked export or a security incident. Treat every item here as pass or fail rather than nice to have.
| Checklist item | Why it matters | Score |
|---|---|---|
| DGAQA and CEMILAC record structures and airworthiness documentation | Indian defence airworthiness needs specific evidence trails that generic ERP does not model. | Yes / Partial / No |
| Export-control classification, licence tracking and deemed-export flags | Handling controlled technology without licence discipline is a legal and reputational risk. | Yes / Partial / No |
| Role-based access control down to record and field level | Need-to-know is a security requirement, not a preference, on defence data. | Yes / Partial / No |
| Immutable audit trail on every transaction | Auditors ask who changed what and when; a mutable log is worthless as evidence. | Yes / Partial / No |
| Data residency and hosting location you can name and control | Defence data often cannot leave the country or the approved environment. | Yes / Partial / No |
| Encryption at rest and in transit with documented key management | Contractual and regulatory security baselines demand it and auditors verify it. | Yes / Partial / No |
Ask the hard questions in this block explicitly. Where is my data physically stored? Who among the vendor staff can access it and under what controls? Can you segregate controlled technical data from general users? If a vendor cannot answer these in the room, they are not ready for defence work.
Block 3: Technology
Technology choices decide how well the platform will age. The goal is a system you can extend and integrate for a decade without being trapped by proprietary lock-in or a stack that cannot scale with your programmes.
Architecture and integration
- Cloud, hybrid or on-premise options that match your security posture. Why it matters: some defence work must run in a controlled or isolated environment.
- Open, documented APIs for MES, PLM, CAD, CMM and customer portals. Why it matters: an ERP that cannot talk to your engineering and shop-floor systems becomes an island of re-keyed data.
- Real-time integration rather than nightly batch where it matters. Why it matters: planning and quality decisions need current data, not yesterday.
Customization, ownership and scale
- Configuration versus code customization clearly delineated. Why it matters: you want to tailor behaviour without forking the product into an un-upgradable state.
- Ownership of custom code and configurations spelled out. Why it matters: if you paid for it and cannot take it with you, you are locked in.
- Scalability across users, sites, programmes and transaction volume. Why it matters: winning a large programme should not force a re-platform.
- Documented upgrade path and backward compatibility. Why it matters: security and feature updates must not break your customizations every cycle.
For an Indian aerospace supplier, a pragmatic and increasingly common answer is a configured platform on a mature business suite extended with purpose-built controls for airworthiness, FAI and export compliance. That model gives you a proven core, faster time to value and a clear line between vendor-maintained platform and your own configured logic.
Block 4: Vendor and implementation
The software is only half of what you buy. The other half is the team that configures it and the methodology that gets you live without stalling production. In aerospace, domain fluency is not a soft factor; a partner who has never seen an AS9102 form will burn your budget learning on your programme.
| Checklist item | Why it matters | Score |
|---|---|---|
| Demonstrable aerospace and defence domain experience | Domain knowledge shortens configuration and avoids compliance blind spots. | Yes / Partial / No |
| Named local support with response-time commitments | A stalled line cannot wait on a time-zone-distant support queue. | Yes / Partial / No |
| Reference customers you can call, ideally in your segment | References reveal how the vendor behaves after the contract is signed. | Yes / Partial / No |
| A phased implementation methodology with clear stage gates | Big-bang cutovers in manufacturing carry avoidable production risk. | Yes / Partial / No |
| Realistic timeline mapped to your production calendar | Go-live during a delivery peak is a self-inflicted wound. | Yes / Partial / No |
| Role-based training and post-go-live hypercare | Adoption, not installation, is what determines return on the investment. | Yes / Partial / No |
Probe the implementation plan for data migration specifics. How will they cleanse and migrate your item master, BOMs, open orders and historical traceability? A vague answer here predicts a painful cutover. Ask who exactly from the partner will be on site, what their aerospace experience is, and how knowledge transfers to your team so you are not dependent on the vendor forever.
Block 5: Commercial
Commercial terms are where a good technical decision can still turn into a bad deal. Look past the licence sticker price to the full cost of ownership and to the terms that govern what happens when the relationship changes.
- Transparent pricing model with named cost drivers. Why it matters: per-user, per-module and consumption charges can multiply quietly as you grow.
- Total cost of ownership over five years, not year one. Why it matters: implementation, integration, training, support and infrastructure often exceed the licence.
- Clear contract terms on SLAs, data ownership and liability. Why it matters: these clauses only matter when something goes wrong, which is exactly when you need them.
- A defined exit and data-portability clause. Why it matters: you must be able to leave with your data in a usable format if you ever need to.
- Change-request and enhancement pricing agreed up front. Why it matters: open-ended change rates can turn every future need into a negotiation.
Build a simple five-year cost model and ask each vendor to populate it on the same basis. The table below shows the cost categories most buyers underestimate; making them explicit prevents the classic surprise where year-two costs dwarf the licence you thought you were buying.
| Cost category | Often missed because | Ask the vendor |
|---|---|---|
| Implementation and configuration | Quoted as a range, not a scope | What is fixed versus time and materials? |
| Integrations | Assumed to be included | Which connectors are priced separately? |
| Training and change management | Left to the buyer | What is included and what is extra? |
| Infrastructure and hosting | Passed through later | Who pays for the environment and backups? |
| Support and upgrades | Percentage of a growing base | How is the annual fee calculated? |
How to run the evaluation
A checklist works only if you use it consistently. Convene a small committee that includes production, quality, programme management, finance and IT, and give each function ownership of the block it knows best. Have every shortlisted vendor demonstrate against the same scripted scenario built from your own data: release an engineering change, plan and build a serialised assembly, raise and disposition a non-conformance, complete an FAI, and produce the traceability and export records on demand. Score each block, then weight compliance and security highest because those are the items you cannot fix later with a workaround.
Resist the pull of the best-looking demo. The platform that wins should be the one that scored honestly across all five blocks against your real requirements, backed by a partner who understands airworthiness and can name a local team. When you have scored your shortlist, the gaps you find become your negotiation agenda: fixed-scope pricing for the Partials, contractual commitments for the roadmap items, and a walk-away position on any compliance No that cannot be closed. That discipline is what turns a checklist from a formality into the reason your ERP programme succeeds.
Key Takeaways
- Treat the checklist as a scoring tool: rate every vendor Yes, Partial or No against the same items using your own data, not a demo dataset.
- Weight compliance and security highest; a single No on export control, DGAQA and CEMILAC records or data residency should stop the deal.
- Functional fit is proven live, so make each vendor release an engineering change, build a serialised assembly, complete an FAI and produce traceability records.
- Model total cost of ownership over five years and force implementation, integration, training, hosting and support into the open before comparing prices.
- Aerospace domain experience in the implementation partner is decisive; a generalist learns on your programme at your expense.
- Use the gaps you find as your negotiation agenda: fixed pricing for Partials, contractual commitments for roadmap items and a walk-away on unresolved compliance No.
Frequently Asked Questions
A complete checklist covers five blocks: functional fit (BOM, MRP, AS9100 quality, AS9102 FAI, NADCAP, traceability, MRO, EVM, procurement and GST e-invoice), compliance and security (DGAQA and CEMILAC records, export control, access control, audit trail and data residency), technology (cloud options, integrations, customization, code ownership and scalability), vendor and implementation (aerospace experience, local support, references, methodology, timeline and training) and commercial (pricing model, total cost of ownership, contract and exit terms). Score every shortlisted vendor against the same items.
Aerospace and defence ERP must carry airworthiness evidence, serial and lot genealogy, First Article Inspection to AS9102, NADCAP special-process control and export-control discipline as native capabilities rather than add-ons. A standard ERP built for distribution can record transactions but cannot easily prove the exact configuration delivered, retire life-limited parts or produce an audit-ready compliance trail. That difference is why a specialised checklist matters.
In aerospace and defence a compliance gap does not generate a support ticket; it generates a lost approval, a blocked export or a security incident. A single No in the compliance block, such as no export-control classification or no data-residency control, can invalidate the whole deal because the consequences are legal and contractual rather than merely inconvenient. Weight this block highest in your scoring.
Build one scripted scenario from your own part numbers, BOMs and routings, then have every vendor run the same steps live: release an engineering change, plan and build a serialised assembly, raise and disposition a non-conformance, complete an FAI and produce traceability and export records on demand. Scoring against identical, real-world tasks prevents the polished sample dataset from hiding gaps you would only discover after go-live.
Buyers routinely underestimate implementation and configuration scope, integration connectors assumed to be included, training and change management, infrastructure and hosting, and support fees calculated as a percentage of a growing base. Model five years rather than year one and ask each vendor to populate the same cost categories so you compare on a common basis instead of comparing licence stickers.
Yes. For Indian manufacturers the platform must generate compliant tax invoices with IRN and produce e-way bills that reconcile with dispatches. If e-invoice and e-way handling is a manual bolt-on, you risk mismatches between your logistics and your tax records, which creates both compliance exposure and reconciliation overhead.
It is decisive. A partner who has configured airworthiness records, AS9102 forms, NADCAP process control and export flags before will shorten your project and avoid compliance blind spots. A generalist partner learns on your programme, which burns budget and timeline. Always ask who specifically will be on site, what their aerospace background is and how they will transfer knowledge to your team.
The right answer follows your security posture and contractual obligations. Some controlled defence work must run in an isolated or in-country environment, while other operations benefit from the scalability and lower maintenance of cloud. Insist on options rather than a single mandated model, and confirm you can name and control where controlled technical data physically resides.
Earned value management measures cost and schedule performance against a baseline so you can report objectively on programme health. Defence customers review long programmes in EVM terms, so your ERP must structure work into programmes and projects that generate earned value data. Without it you cannot report progress in the language your customer expects at a programme review.
Insist on documented open APIs, a clear line between configuration and code customization, explicit ownership of any custom code you pay for, and a defined exit clause that lets you export your data in a usable format. Lock-in is created by proprietary integrations, un-portable data and configurations you cannot take with you, so address each of those in the contract before signing.
Elite Tech Corporation offers a working copy of this aerospace ERP buying checklist that your evaluation committee can print and score. Reach out through our contact page to request the download and, if useful, a walkthrough of how a configured platform on a mature business suite can meet the functional, compliance and commercial items in each block.
Include production, quality, programme management, finance and IT, and give each function ownership of the block it knows best. Quality should own the AS9100, FAI and NADCAP items, programme management the EVM and billing items, finance the commercial block, and IT the technology and security items. Shared ownership means every risk is scored by someone qualified to judge it.
Conclusion
An aerospace ERP decision is too consequential to make on a demo and a discount. The platform you choose will carry your airworthiness evidence, your programme reporting and your export discipline for a decade, so evaluate it with the rigour that responsibility deserves. Work through all five blocks, score honestly against your own requirements, and let the gaps guide your negotiation rather than your enthusiasm. Elite Tech Corporation configures ERP for aerospace and defence manufacturers on a mature business suite extended with purpose-built airworthiness, First Article Inspection and export-control controls, backed by a Bengaluru team that has done this work before.
