Calibration management priced for quality managers, not enterprise budgets

No free tier — but every paid plan starts with a 14-day trial. No card required to start. Cancel any time before the trial ends and nothing is charged.

Yes. Upgrade, downgrade, or cancel from the billing portal at any time. Plan changes take effect at the next billing cycle. No long-term contracts and no per-user add-on fees.

Annual billing saves around 15% versus monthly (Starter £296/year vs £348, saves £52; Pro £602/year vs £708, saves £106). Billed up-front, renews automatically. You can switch between monthly and annual at any time from the billing portal — the change takes effect at the next renewal so you keep the time you have already paid for. The 14-day trial works the same regardless of which interval you pick at signup.

Starter supports up to 3 users sharing the same workspace (a quality manager + a workshop supervisor + a quality engineer, for example). Invite teammates by email from the Team settings — they get a 7-day link, click it, sign up if needed, and join your workspace. Pro removes the seat cap — unlimited users on the same workspace, capped only by the 500-instrument limit.

You’ll see a banner at 80% and a hard stop at 100% — new instrument creation is blocked, but existing instruments stay editable. Upgrade to Pro to unlock 500-instrument capacity. Existing data is never lost or hidden when you change plans.

You keep full access until the end of your paid period. After cancellation, your workspace enters a 30-day grace where you can still export or reactivate; on day 31 your calibration data and certificate PDFs are permanently deleted. The audit log is retained for 7 years from your last activity to satisfy ISO 9001 / ISO 17025 record-retention obligations — that is the only category we keep beyond day 31. Pro tier includes Export Everything, and a compliance-bypass makes it available even if your subscription has lapsed, so leaving with your data is never gated. See /legal/retention-and-deletion/ for the full policy.

Pro tier includes Export Everything — one ZIP with the full register, calibrations, OOT events, certificate PDFs, audit-log JSONL, and audit-report PDFs. Generated synchronously for ≤500 instrument workspaces; emailed as a signed link otherwise. Designed so leaving is never a sunk-cost issue.
