For HVAC and trade shops

Software built around
how your shop runs.

I'm Mat Strommen. I build one app around how your shop already works, from the first call to the paid invoice, in place of the stack of subscriptions that each cover a slice of the job. It starts with a walk-through of how your jobs move today.

01 / One job, start to finish

Most shops run a job across a phone, a scheduling tool, a paper ticket, an invoicing tool, and someone's memory. Every handoff is a place for a job to stall or a detail to get retyped wrong. Here is the same job in one app.

  1. 01 Call comes in Caller matched to their record, equipment and past visits on screen
  2. 02 Estimate Nameplate photo read, unit age and likely parts listed before anyone drives out
  3. 03 Scheduled Calls grouped by area, the ones promised soonest first
  4. 04 On site Technician asks questions against that unit’s manual and history
  5. 05 Complete Hours, parts and notes land on the job, not on paper
  6. 06 Invoiced Invoice built from the job record, which can’t be invoiced until it’s finished
  7. 07 Paid Payment closes the job and the numbers flow to the books
One job, one record, from the first call to the paid invoice. The record decides what can happen next, so nothing falls between the office and the truck.

02 / It starts with a walk-through

02.1

We map how a job moves today.

Before building anything, I sit with you and the office and follow real jobs from the first call to the paid invoice. Where does it wait? What gets typed twice? What lives only in someone's head?

02.2

You get a clear list.

Most owners know where it hurts without having a list of requirements. The walk-through produces that list: what works, where the gaps are, and what the app would need to do.

02.3

Then the build follows the list.

The app is built to fit how your shop runs, one piece at a time, starting with whatever costs you the most time now.

03 / What you'd get

03.1

No fee per seat.

After the build you pay for hosting and an AI account, not a monthly charge for every technician on every tool.

03.2

Changes in plain English.

Need a new field on the ticket or a different report? Ask for it in plain English, and the change is made, tested and put live.

03.3

A change can't wreck your Monday.

Every change is tested before it goes live. If one still turns out wrong, the app goes back to the last version that worked.

03.4

Your data is backed up every night.

Nightly backups, plus a copy kept off-site. Restoring is a written procedure, not a scramble.

03.5

A person signs off on the money.

AI can draft, sort and look things up. Anything that spends money, commits you publicly or deletes data waits for a person.

03.6

Built for the phone.

A trade business runs on calls. Appointment reminders, call notes on the customer record, and after-hours calls answered and logged are early priorities.

04 / What this is based on

04.1

We run our own business on one.

Strommen Systems buys surplus equipment, repairs it, and sells it. One app we built runs all of it: sourcing, repair tickets, listings, pickups, shipping and the books, with the same testing and backups described above. Here is how it works, with screenshots.

04.2

We haven't built one for an HVAC shop yet.

That's the honest part. The pieces carry over: a job record in place of an item record, reading a furnace nameplate the way we read a lab instrument's, and dispatch that works like our pickup board. We're looking for a few local shops to walk through first.
