Know exactly how audit-ready
your lab is. Right now.

Lab compliance software replaces the spreadsheets, paper logs, and shared drives most labs use to track calibration, training, EQA, maintenance, and controlled documents. Accredited labs need it because standards like ISO 15189, CAP, CLIA, and UKAS all require documented evidence — current calibration certificates, training records with competency assessments, EQA participation with corrective actions, preventive maintenance logs, and controlled SOPs with acknowledgments. CalibDue centralises every requirement, automates reminders so nothing slips, and produces audit-ready PDF exports on demand.

ISO 15189 covers far more than calibration — it requires documented competency, EQA participation, equipment maintenance, and controlled documents. CalibDue is purpose-built for ISO 15189 and supports CAP, CLIA, and UKAS too. It stores calibration certificates, tracks competency and training, manages EQA programs with z-score trending and corrective actions, runs preventive maintenance, controls SOPs with versioning and acknowledgments, and generates audit-ready reports formatted for your accreditation standard.

Both CAP and CLIA require successful PT participation and corrective action on unacceptable results, but the specifics differ. CLIA mandates that two out of three consecutive unsuccessful events trigger a regulatory event, with PT integrity attestation at submission and a 30-day window to review the evaluation report. CAP applies its own consecutive-failure logic and also enforces PT integrity attestation. CalibDue's EQA module enforces the right rule per accreditation standard automatically — you don't have to remember which rule applies where.

Yes. The Training & Competency module lets you define training topics (per equipment or procedure), assign them to users, log training records with evidence uploads, and conduct competency assessments. You get a full competency matrix (topics × users), a five-state status per user (compliant, expiring soon, non-compliant, pending assessment, not started), a lab-wide training readiness score on the dashboard, and automated reminders before any expiry — plus PDF training reports for audits.

Yes. The EQA module covers the full workflow: you add your own providers by name — whoever you actually use — with built-in report-import mappings for the CAP, RCPA and RIQAS result-file formats; then programs, analytes with z-score acceptable and warning thresholds, rounds, lab and provider result entry with auto-suggested acceptability, round status transitions, corrective actions with effectiveness verification, consecutive-failure detection per accreditation standard, and an EQA participation score on the dashboard. PT integrity attestation and review-window enforcement are built in.

Every instrument can have multiple calibration schedules (e.g. pressure test + temperature calibration on one analyser). Each schedule tracks status as current, due soon, or overdue. Reminders fire automatically by email 30, 7, and 1 day before due, plus an on-overdue alert. You can log calibrations with date, result, technician, and attached certificate — or generate certificates from a branded template with sequential numbering. The Equipment register stores serial numbers, locations, suppliers, and full calibration history.

Preparing for an audit means having every calibration, training record, EQA result, maintenance log, and controlled document up-to-date and easy to retrieve. CalibDue gives you a live readiness score for each area so you always know where you stand. With one-click PDF exports (calibration audit report, training report, document register, maintenance report), centralised evidence storage, and automated reminders across every module, you go from weeks of preparation to minutes — and walk into every inspection with confidence.

Not yet — and we would rather tell you now than after onboarding. CalibDue today serves one accredited lab per account, with strict data isolation between accounts enforced at the middleware layer. Multi-site consolidated oversight is on the roadmap and is the next architectural change we are making; if you run several accredited sites, email contact@calibdue.com before you start a trial and we will tell you honestly whether we fit yet, rather than sell you something that does not.

Three roles. Admins configure modules, manage equipment and SOPs, invite team members, and access reports and settings. Technicians log calibrations, training, maintenance, and EQA results — and acknowledge documents assigned to them. Viewers see the dashboard and registers in read-only mode, ideal for auditors, consultants, or upper management. All actions are recorded in an append-only activity log so every change has an attributable trail.

The Document Control module manages your controlled SOP register with multi-version uploads (SHA-256 checksum on every file), a multi-reviewer approval workflow, and per-version acknowledgment tracking. When a new version is approved, assigned staff are notified and must acknowledge — admin can also bulk-acknowledge after a training session. Periodic review schedules ensure documents are reviewed before they go stale, and a compliance score on the dashboard shows what's pending.

Data isolation is enforced at the middleware layer: every authenticated request is scoped to your organisation, and there is no cross-organisation API surface to bypass. We verified this with a 15-endpoint cross-tenant sweep that produced zero leaks. Authentication is cookie-based session auth (Laravel Sanctum) with rate limiting on every public endpoint. Every uploaded file — calibration certificates, document versions, evidence — is stored with a SHA-256 checksum so tampering is detectable, and downloads are served through short-lived signed URLs that expire after 15 minutes rather than permanent public links. Destructive actions are soft-deleted and written to an append-only activity log with the actor stamped server-side. We are a new vendor and we will not pretend otherwise: we hold no SOC 2 or ISO 27001 certification today, and our current backup and encryption posture is documented in full on our security page rather than summarised into a badge. If your procurement process needs written answers, ask and we will send them.

Yes, CalibDue is available now. Signup is self-serve at app.calibdue.com/signup: you create your lab, pick your accreditation standard, and start using it immediately on a 14-day free trial with no credit card. There is one plan at $59 per month, billed monthly in US dollars — no tiers, no per-seat charge, and the audit export is included rather than sold as an upgrade. Paid checkout is not open yet while we finish setting up Paddle as merchant of record, so the trial is the only way in today and nothing can be charged to you before then. If the trial ends before you subscribe, your lab becomes read-only — everything you recorded stays visible, an administrator can still generate the audit export, and nothing is deleted. Full detail is on the pricing page.
