One platform, the whole calibration lifecycle
From the first walkthrough to the renewal reminder — no spreadsheets, no re-keying into QuickBooks.
Service Agreements
The annuity book — per-device intervals, locked rates, perks, and auto-renewals that keep the revenue recurring.
HB 44 Tolerance Engine
Server-judged as-found / as-left readings against NIST Handbook 44 — the metrology moat, unit-tested against the source tables.
Mobile Field Capture
Techs capture readings, standards, seals, and signatures on any device — fully offline, syncing when back in range.
Certificates & Portal
Immutable, revision-tracked certificates with QR verification, auto-emailed and published to a branded customer portal.
Automated Invoicing
Per-device lines draft themselves from the visit at agreement rates, push to QuickBooks — the office just reviews.
Due Engine & Dispatch
Devices coming due auto-generate unassigned work orders, grouped by site and due window, ready for the calendar.
How it works
A single path, onboarding to renewal
Onboard
Import devices from QuickBooks + Excel, or capture them on-site during a free walkthrough.
Agree
Sign a service agreement with per-device intervals and locked rates — the due clock arms itself.
Dispatch
Due devices auto-create work orders, grouped by site, dropped straight onto the calendar.
Calibrate
Techs run pre-test, as-found & as-left readings judged live by the HB 44 engine — even offline.
Certify & bill
Certificates publish to the portal and per-device invoice lines draft automatically. Done.
Scale pros run their business on it
We stopped re-keying certs into QuickBooks. The visit closes, the certificate publishes, and the invoice is already drafted. It gave our office manager her afternoons back.
Dana Whitfield
Owner, Precision Scale Co.
The HB 44 engine judges every reading on the tablet — even with no signal in a grain elevator. Our techs trust it, and so do the state inspectors.
Marcus Reed
Service Manager, Delta Weighing
Agreements plus the due engine mean work orders just appear when scales come due. Our recurring revenue is finally on autopilot.

Questions, answered
No. We migrate your customers, devices, and last-known calibration dates for you during onboarding — importing from QuickBooks and a device spreadsheet, or capturing them on-site during a free walkthrough.
Yes. Each visit ships its test plan and tolerances to the device up front, so as-found and as-left readings are judged instantly in the field — even with no signal — and sync when the tech is back in range.
Certificates freeze the exact HB 44 edition, class, and tolerances applied that day, track revisions immutably, and carry the technician's signatory details — built to the standards your customers are audited against.
Per-device invoice lines draft themselves from the visit at each device's agreement or list rate, suppress the trip charge when travel is included, and push to QuickBooks. Your office just reviews and sends.
Yes. Calibration rides on top of the existing work-order, scheduling, and invoicing rails — the due engine simply drops auto-created work orders into the calendar you already use.
