The verdict in three sentences
For a tier-1 supplier managing 90 subcontractors by email, a custom supplier quality portal costs between EUR 40,000 and 110,000 (about USD 43,000 to 120,000) depending on how many processes it covers. The most measurable gain is a reduction of roughly 30% in processing times for nonconformances and 8D reports, with traceability that stands up in an EN 9100 / AS9100 audit. Custom makes sense when your processes differ from those built into your PLM quality modules or when your suppliers refuse a per-user licence.
What the portal must cover, and what it costs
In aerospace clusters such as Montreal or Toulouse, most tier-2 and tier-3 subcontractors are SMEs with 20 to 150 employees. They receive quality requests from several primes, each with its own Excel format. The portal must therefore be simple for the supplier and rigorous for the customer.
| Module | Main function | Indicative 2026 cost (EUR, excl. VAT) | Timeline |
|---|---|---|---|
| Core, accounts and per-supplier permissions | Internal SSO, external accounts, rights by site and part family | 8,000 to 15,000 | 4 to 6 weeks |
| Nonconformances and online 8D | Reporting, photos, D1 to D8 steps, automatic reminders | 10,000 to 25,000 | 6 to 8 weeks |
| FAI EN 9102 / AS9102 | Forms 1, 2 and 3, attachments, approval and history per part number | 8,000 to 22,000 | 5 to 8 weeks |
| Supplier document management | EN 9100, Nadcap certificates, due dates, expiry alerts | 5,000 to 12,000 | 3 to 4 weeks |
| Quality dashboards | PPM, quality OTD, average 8D closure time, supplier ranking | 5,000 to 18,000 | 3 to 6 weeks |
| ERP and PLM integrations | Sync of part numbers, work orders and lots via API or files | 4,000 to 18,000 | 3 to 8 weeks |
A minimal scope (core, 8D, documents) sits around EUR 40,000 to 55,000. The full scope with FAI, dashboards and integrations reaches EUR 90,000 to 110,000. Then budget 15 to 20% of the initial cost per year for maintenance, sovereign hosting and enhancements.
Custom portal or PLM suite modules?
The major PLM and QMS suites offer supplier modules. They are robust but designed for standard processes, with a per-external-user licence that becomes heavy when each supplier has three or four quality contacts.
| Criterion | Custom portal | Supplier module of a PLM/QMS suite |
|---|---|---|
| Initial cost | EUR 40,000 to 110,000 | EUR 30,000 to 80,000 of configuration |
| External licences | None, unlimited users | EUR 40 to 120 per user per month |
| 3-year cost for 90 suppliers (270 accounts) | EUR 60,000 to 165,000 | EUR 420,000 to 1,250,000 with licences |
| Fit with internal processes | Full, custom forms and workflows | Partial, frequent workarounds |
| Adoption by SME suppliers | Clean, mobile-friendly interface | Rich but heavy interface |
| Time to go live | 4 to 6 months | 6 to 12 months with an integrator |
| Vendor lock-in | Source code delivered | Strong, roadmap imposed |
The PLM module remains relevant if your group already runs it and only a few strategic suppliers need access. Beyond 50 active suppliers, the cost of external licences makes custom more profitable from year two (2026 order of magnitude).
Aerospace-specific requirements
The portal must survive an audit. In practice: timestamping of every action, a tamper-proof audit trail, record retention for the life of the programme, drawing version control, and export control if some parts fall under regulations such as ITAR, the Canadian Controlled Goods Program or dual-use rules. Hosting in a qualified local cloud and two-factor authentication for external accounts have become standard among tier-1 suppliers.

Claire, supplier quality manager at a tier-1 aerospace supplier, oversees 90 subcontractors and opens about 420 nonconformances per year. Each 8D takes on average 6 hours of reminders, consolidation and checks on the customer side, i.e. 2,520 hours per year. With a portal that automates reminders and consolidation, her team saves 30%, i.e. 756 hours. At a loaded hourly cost of EUR 65, that is EUR 49,100 per year. For a project at EUR 85,000 plus EUR 15,000 of annual maintenance, payback comes in just under 2 years and 6 months, not counting fewer customer penalties tied to late closures.
FAQ
How much does a supplier quality portal cost in 2026?
Budget EUR 40,000 to 55,000 for a core with 8D and documents, and up to EUR 110,000 with EN 9102 FAI, dashboards and ERP integrations. Maintenance runs 15 to 20% per year.
How long does it take to go live?
The usual timeline is 4 to 6 months, including 3 to 4 weeks of scoping. A pilot with 10 suppliers is recommended before opening to all 90.
Will suppliers have to pay for a licence?
No, a custom portal has no per-user licence. That is the main gap versus PLM modules billed EUR 40 to 120 per account per month.
Is the portal compatible with an EN 9100 / AS9100 audit?
Yes, provided audit trail, timestamping and long-term retention are designed in from the start. These requirements add about 10% to the budget but prevent audit findings.
Can we migrate our Excel 8D history?
Yes, migrating 3 to 5 years of history usually costs EUR 3,000 to 8,000 depending on file quality.
