The verdict in three sentences
For a 180-employee aerospace supplier near Manchester handling 600 non-conformances a year, a custom non-conformance management app costs, as a 2026 order of magnitude, 30,000 to 70,000 GBP and takes 3 to 4 months to deploy. An off-the-shelf QHSE suite runs at 10,000 to 26,000 GBP per year, often more over three years for a use limited to the NCR module. The decisive argument is the AS9100 audit: traceable corrective actions, closure time down from 60 to 25 days and evidence exported in one click.
What the AS9100 auditor really looks at
AS9100 (the aerospace version of ISO 9001) requires control of nonconforming outputs (clause 8.7) and corrective action (clause 10.2), with traceability, root cause analysis and effectiveness checks. With a shared Excel workbook, the weaknesses are well known: competing versions, attachments scattered across the server, actions without owner or due date, no link to batch or serial numbers.
| Requirement (2026 order of magnitude) | Excel tracking | Dedicated app |
|---|---|---|
| Average NCR closure time | 60 days | 25 days |
| NCRs without documented root cause | 30 to 40% | under 5% (mandatory field, 8D or 5 Whys) |
| Undetected overdue corrective actions | frequent | automatic reminder at D-7 and escalation |
| Link NCR, batch, serial number, customer | manual | automatic, found in 2 seconds |
| Annual audit preparation | 8 to 10 days | 1 to 2 days |
| Cost of poor quality tracked | estimated | calculated per NCR (scrap, rework, concession) |
For a supplier whose prime contractor demands monthly KPIs (OTD, PPM, complaints), producing these figures without rework matters as much as the audit itself.
Custom vs QHSE software: a three-year comparison
| Criterion | Off-the-shelf QHSE | Custom app |
|---|---|---|
| Upfront cost | 5,000 to 15,000 GBP configuration | 30,000 to 70,000 GBP |
| Annual cost | 10,000 to 26,000 GBP subscription | 4,000 to 9,000 GBP maintenance and hosting |
| 3-year cost | 35,000 to 93,000 GBP | 42,000 to 97,000 GBP |
| Deployment time | 2 to 3 months | 3 to 4 months |
| Fit with the prime's 8D process | partial | full |
| ERP integration (batches, works orders, suppliers) | standard connectors | custom API |
| Data hosting | vendor cloud | UK server or on-premise, useful for defence-related programmes |
Over three years the costs are close, so the choice depends on scope. Off-the-shelf wins if you want to cover health and safety, environment, internal audits and document control in one go. Custom wins when the need centres on the NCR, customer complaint and corrective action cycle, with rules imposed by your primes, and over five years it usually becomes cheaper.
Typical scope of a 3 to 4 month project
- Reporting from the shop floor on a tablet: photo, part number, batch, workstation, quantity.
- Disposition: scrap, rework, customer concession, return to supplier, with approval routing.
- Root cause analysis: 8D, Ishikawa or 5 Whys, depending on the customer.
- Action plan with owners, due dates, reminders and a 90-day effectiveness check.
- Dashboards: PPM per customer, cost of poor quality, top 10 defects, closure time.
- Audit exports: full NCR file as PDF, annual extract for the auditor.
Mini case study
Emma, quality manager at a 180-employee aerospace supplier near Manchester, handles 600 NCRs a year. Illustrative scenario: each NCR takes on average 3 hours of data entry, chasing and consolidation in Excel, down to 1.2 hours with the app, i.e. 1,080 hours saved per year. At a loaded hourly cost of 40 GBP, that is 43,200 GBP. For a 50,000 GBP app plus 6,000 GBP annual maintenance, payback comes in about 16 months, not counting the reduced risk of a major audit finding.

FAQ
How much does a non-conformance management app cost in 2026?
As an order of magnitude in the UK, 30,000 to 70,000 GBP depending on approval routes and ERP integration depth. Maintenance then runs at 4,000 to 9,000 GBP per year.
Is the app compatible with an AS9100 audit?
Yes if it records disposition, root cause, actions and their effectiveness check, with a tamper-proof history. Exporting a complete file then takes under a minute.
Can we import our Excel history?
Yes, importing the last 2 to 3 years is common (1,200 to 1,800 NCRs) and keeps trend statistics available from day one.
Do shop floor operators need training?
A 30-minute session is enough if reporting fits into 5 fields on a tablet. Quality engineers take a 2-hour session.
Do aerospace programmes need specific hosting?
For sensitive programmes, UK or on-premise hosting is recommended. The extra cost is often 1,000 to 3,000 GBP per year.
