Calibration Schedule & Due Tracker

The problem this kills

Somewhere in your shop there is a caliper, a torque wrench, or a pressure gauge whose calibration sticker quietly expired last month. Nobody noticed. It kept getting picked up off the bench and used to pass or fail product. Now an auditor is asking which lots were inspected with it — and you can't answer cleanly.

Calibration due dates live in a spreadsheet that only one person updates, or on stickers that fade, or in a "system" that is really just somebody's memory. There's no reminder before a due date, no hard stop when an instrument goes out of cal, and no tidy record of who signed off on the last calibration. When the audit comes, you're rebuilding the history from emails and sticky notes.

This tool makes the schedule do the watching for you: it knows every instrument's interval, computes the next due date, warns you in advance, and flips anything overdue into a visible do-not-use / quarantine status before it can be used to make a quality call.

What you'll build

A small, private web app for your quality, metrology, and maintenance teams:

• Import your instrument list from a CSV or Google Sheet (instrument ID, description, location, calibration interval, last cal date).
• The tool computes each instrument's next-due date from its own interval — different instruments can have different intervals.
• A live dashboard shows every instrument color-coded in-cal / due-soon / overdue, with overdue ones flagged as do-not-use.
• Resend emails the right people before a due date, and escalates when something is long overdue.
• When a calibration is completed, the metrology owner reviews and approves the record through a human gate — only then does the status return to "in calibration" and the next due date get set.
• One-click export of the full calibration register CSV with each instrument's current status.

What's inside the Implementation Plan

• It starts by interviewing you about your business. Before writing a single line, the plan has the AI agent ask about your instruments, your naming/ID conventions, your intervals, who owns sign-off, and your weird edge cases — then it tailors the data model and rules to you, not to a generic template.
• A copy-paste prompt for every step, in order, so you never have to know what to type next.
• The exact data model for instruments, calibration events, and the approval gate.
• How to compute due-soon and overdue windows, and how to quarantine overdue instruments.
• The Resend reminder + escalation emails, wired to real due dates.
• The "No API yet?" fallback so you can build the whole thing today from a spreadsheet — no integration with your existing system required.
• A verification checklist so you know it actually works before you trust it.

The governance it includes (this is the point)

This isn't a toy. The plan bakes in the controls a quality system actually needs:

• Login so only your team can open the tool.
• Row-level security so each organization only ever sees its own instruments and records.
• A complete audit trail — who imported, who approved, who changed a date, and when.
• A hard human-in-the-loop approval gate: the AI drafts the completed-calibration record, the metrology owner reviews it, and only an approval sets the next due date and returns the instrument to in-cal.
• Duplicate guards keyed on instrument ID so the same instrument or the same cal event can't be entered twice.

Who it's for

Quality, metrology, and maintenance teams responsible for calibrated equipment — anyone who has to prove, on demand, that the gauge used to make a decision was in calibration at the time. If you can fill in a spreadsheet, you can build this.

You've got this — paste the first prompt and let the agent interview you.
