About CalProof

What CalProof does

CalProof is cloud-based calibration management software for UK manufacturers and laboratories. It tracks your equipment register, automates calibration scheduling, stores certificates with full audit trails, and generates ISO-compliant reports — replacing the spreadsheets that cause most calibration audit findings.

Who it's for

Quality managers, metrology managers, and lab managers at UK SMEs with 10–200 employees and 20–500 calibrated instruments. If you hold ISO 9001, ISO 17025, or UKAS accreditation and currently track calibration in Excel, CalProof is built for your workflow.

Why it exists

Calibration non-conformances are consistently among the top 3 ISO audit findings for UK SMEs. The root cause is almost always the same: spreadsheet-based tracking that can't send reminders, link certificates to equipment, or guide out-of-tolerance investigations. Enterprise tools exist but start at $2,000+ and are designed for large organisations. Affordable cloud options exist but are all US-based with no UK localisation, no UKAS workflow templates, and USD pricing.

CalProof fills this gap: a modern, cloud-native calibration management tool built specifically for UK quality managers, with GBP pricing at £29–99/month and UKAS accreditation workflow support.
