Everything you need

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

01

Onboard

Import devices from QuickBooks + Excel, or capture them on-site during a free walkthrough.

02

Agree

Sign a service agreement with per-device intervals and locked rates — the due clock arms itself.

03

Dispatch

Due devices auto-create work orders, grouped by site, dropped straight onto the calendar.

04

Calibrate

Techs run pre-test, as-found & as-left readings judged live by the HB 44 engine — even offline.

05

Certify & bill

Certificates publish to the portal and per-device invoice lines draft automatically. Done.

Loved in the field

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.

FAQ

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.
