What it does

From the 6am call‑out to the paid invoice.

Four jobs the office used to chase by phone, done in one place.

Schedule and dispatch

Drag a job onto a tech, and it's in their van before they've finished the last one. See who's closest to a breakdown.

Job sheets on site

Notes, photos, parts used and the customer's signature, captured on a phone. Works in plant rooms with no signal.

Refrigerant logs

Every kilogram added and recovered, tied to the job, the site and the cylinder. Ready when the auditor asks.

Quote to invoice

Turn a quote into a job and a closed job into an invoice, then send it to your accounting software in one click.

Compliance

Refrigerant records that pass an audit.

We kept these logs in ring binders for 20 years. Now they fill themselves in as the tech closes the job.

  • Logged at the job. Gas type, quantity and cylinder are required fields, so nothing gets written up later from memory.
  • Tracked by cylinder. Know what's left in every bottle and which jobs it went into.
  • Licences checked. A job that needs a refrigerant licence can only go to a tech who holds a current one.

Our story

Built in the van, not the boardroom.

Optimyst started as Reid Refrigeration, a Brisbane service business. We built the software for our own technicians. Other contractors asked to buy it.

“Every 3am breakdown is an opportunity.”

Ray Reid, founder of Reid Refrigeration. The reason we're called Optimyst.
  1. 1994

    Reid Refrigeration opens

    Ray Reid services cool rooms and commercial air-con for restaurants, supermarkets and clubs across Brisbane.

  2. 2015

    Hannah Reid takes over

    40 technicians, paper job sheets and refrigerant logs in ring binders.

  3. 2018

    The app is built for our own vans

    Scheduling and compliance on a phone, so techs stop doing paperwork in the cab.

  4. 2020

    Optimyst

    Software revenue overtakes servicing. The company takes a new name. Reid Refrigeration keeps running as our service division and test bed.

  5. 2026

    About 1,400 contractors

    85 people across Brisbane and Wellington. Every feature still goes out in our own vans first.

Questions contractors ask first.

Does it work without signal?

Yes. Job sheets, photos and signatures save on the phone and sync when the tech is back in range.

Can we bring our old jobs across?

We import your customers, sites and equipment from a spreadsheet. Most businesses are running jobs within a week.

Is it only for refrigeration?

It started there. Air-conditioning and electrical contractors use the same scheduling, job sheets and invoicing.

Who will we talk to for support?

Our support team in Brisbane and Wellington. Several of them have held a refrigerant licence.
