Maintenance management with records that survive an audit

NexIndu manages work orders, preventive maintenance, inventory and shift handovers in regulated plants. Every record is signed, timestamped in plant time and protected by an immutable audit trail.

  • Electronic signatures with identity re-verification on every closure
  • Immutable audit trail with record-by-record hash chaining
  • Immutable plant-time date and time on every operation

A day of work on the floor with NexIndu

Five everyday maintenance moments — and what gets recorded in each one.

When every record is born audit-ready, inspections stop being an event

NexIndu structures daily operations so compliance is not a separate chore: it is the natural by-product of doing the work.

  1. 01 · Record

    Everything is written down in the moment

    Work orders, interventions and handoffs are recorded in plant time, with an identified author and drafts that never get lost.

  2. 02 · Control

    Every action has an owner and a signature

    Per-person roles and permissions, electronic signatures with identity re-verification, and a chain of custody on every shift handoff.

  3. 03 · Prove

    The evidence is already there

    An immutable audit trail with chained hashes, KPIs that open the exact list they come from, and reports ready for the inspector.

One platform for the entire maintenance operation

Eight modules built on the same traceability core. No parallel spreadsheets.

  • Featured module

    Work orders

    From failure report to signed closure, with every intervention recorded separately.

  • Featured module

    Analytics

    MTTR, preventive-plan compliance and asset Pareto, auditable down to the individual order.

  • Preventive maintenance

    Template-based plans, calendar view and due-date alerts per asset.

  • Assets

    Machine and sub-asset hierarchy with a full history per piece of equipment.

  • Inventory

    Spare parts with minimum stock, alerts and costs tied to each work order.

  • Audit trail

    An immutable record of every action, with chained hashes and inspection-ready export.

  • Shift handover

    Immutable shift reports with a chain of custody between technicians.

  • Credentials vault

    Encrypted HMI credentials with per-person audited access.

Verifiable compliance, requirement by requirement

Every regulatory requirement is answered with a concrete technical control you can verify in the system. This is the short version.

21 CFR Part 11 §11.10(e)Secure, computer-generated, time-stamped audit trailAppend-only audit log: the database rejects updates and deletes, and every event is hash-chained to the previous one.
21 CFR Part 11 §11.50 + §11.70Electronic signatures with meaning, linked to their recordEach signature requires re-verifying a password or biometrics and stores the signer, meaning, date and a permanent link to the signed record.
EU GMP Annex 11 §9Recording of changes and deletions of critical dataCritical records are never physically deleted: they are flagged as removed and the change is written to the audit trail.
EU GMP Annex 11 §12Access controls for the system and its dataIndividual accounts with roles and permissions, and per-organization isolation enforced row by row in the database itself.
ALCOA+ · AttributableEvery data point has an identified authorEach record stores who created it, who modified it and who signed it. There are no shared accounts.
ALCOA+ · ContemporaneousData recorded at the time of the operationTimestamps are set by the server in the plant's declared time zone and cannot be edited afterwards.
