Quality Control System for Manufacturing
A custom quality control system that connects digital inspection checklists, non-conformance reporting, CAPA workflows and audit-ready records into one source of truth. From incoming raw material to final inspection, you run QC in real time — no paper travelers, no lost protocols, no guessing who accepted what.
What the QMS covers
Inspection checklists
Parametric checkpoints per item, operation and workstation. Inspectors see only the questions that matter right now, with critical, major and minor characteristics clearly separated.
Non-conformance reporting
When something fails, an NCR opens with photos, measurements and root cause. The lot is auto-blocked and the QA owner gets a task before the operator leaves the station.
CAPA workflows
Every NCR drives a corrective and preventive action with 5 Why or Ishikawa root-cause analysis, owners, deadlines and effectiveness verification. Nothing gets lost in email threads.
AQL sampling plans
Built-in ISO 2859-1 tables for incoming, in-process and outgoing control. The system sizes the sample by lot and risk profile automatically.
Supplier quality management
Supplier scoring by defect rate, on-time delivery and NCR response. The system flags when a supplier should move to skip-lot inspection — or back to 100%.
Mobile inspection app
Inspectors work from a tablet or rugged terminal — capture photos, pull measurements over Bluetooth, sign off. Works offline, syncs on reconnect.
Who it fits
Mass production
High volumes, short cycles, constant pressure for stable quality. SPC charts warn before the process drifts out of tolerance, not after thousands of bad units are already packed.
Food and pharma
HACCP critical points, temperature logs, lot genealogy. In a recall you find affected lots and customers in minutes; auditors see a complete chain end to end.
Automotive suppliers
IATF 16949-ready: PPAP packages, FMEA, control plans and measurements all linked. You pull a full quality file for a new OEM project in minutes.
How we build it
We do not resell someone else's QMS platform. We build your own quality control system on a proven stack: PostgreSQL for data, .NET or Node.js for business logic, React/Next.js for the web portal, React Native for the mobile inspection apps. REST APIs and webhooks connect the system to your ERP and MES.
We spend a few days on the floor reading your current checklists, ISO procedures and work instructions. From the real process we lock the MVP scope — typically incoming inspection, in-process checkpoints, NCR and base CAPA. Supplier scoring, SPC and audit management ship in later phases.
See how we connect it to manufacturing traceability software for full lot genealogy, and to route planning software when inspectors visit several sites a day. We also integrate measurement devices over RS-232, Bluetooth and OPC UA — calipers, scales, leak testers — so values land in the record without manual transcription.
Go-live happens in stages: one process or line first, then the shop, then across sites. We prepare users for ISO audits — standard reports, signed audit trails, backup copies. After go-live we stay on an SLA support contract. See also our custom software development service for adjacent process tooling.
Why Saitami for your quality control system
Scrap reduction
Average drop in scrap 12 months after go-live, measured on real client data across metalworking and food production deployments.
Audit-readiness
Preparation time for ISO 9001, IATF 16949 and BRCGS audits drops sharply — records appear in minutes instead of weeks.
Starting investment
Fixed price for the MVP phase. No per-user licensing, no hidden subscription. You own the system outright.
A quality control system often runs alongside custom ERP development on one architecture — a single database for orders, inventory, production and quality. Ready to see how QMS fits your picture? Get in touch.
Frequently Asked Questions
How long does a quality control system take to implement?
A quality control system at Saitami takes between 5 and 12 weeks to reach the first productive phase. A small manufacturer with one inspection flow goes live in 5-7 weeks. A mid-size plant with incoming, in-process, final inspection and supplier scoring lands around 10-12 weeks. We never do a big-bang go-live; we start with the most critical checkpoint and expand in stages from there, alongside daily operations.
Is the system suitable for ISO 9001 and HACCP audits?
The system is built for ISO 9001, IATF 16949, BRCGS and HACCP audit-readiness. Every record carries an audit trail with user, timestamp and electronic signature; checklists meet documented-process requirements; NCR and CAPA modules cover clauses 10.2 and 10.3 of ISO 9001. Your auditors move through the data quickly because the structure was designed exactly for that, not retrofitted onto a generic platform.
Can it integrate with existing ERP and MES systems?
The quality control system integrates with existing ERP and MES in almost every project. We connect to SAP, Microsoft Dynamics, Microinvest, Plus Minus, Ajour and custom ERP/MES platforms through REST API, file exchange or direct database hand-off. Lots inherit QC records without double entry, and NCR blocks reflect instantly in stock. You keep your current systems while the QMS owns quality control.
How much does a quality control system cost?
A quality control system at Saitami starts from EUR 5,800 for an MVP rollout at a small manufacturer and typically lands between EUR 15,000 and EUR 36,000 for a mid-size plant with multiple production lines, supplier scoring and ERP integration. Pricing is fixed against the agreed scope, paid in milestones and never includes per-user fees. Post-go-live support is a separate SLA contract.
