Shop software for mechanical contractors

Your back office, installed.

DSM runs the parts of a contracting company that aren't on the roof — dispatch, quoting, invoicing, collections, the phones, the trucks. One system, on your own hardware.

A day on it

The office is already caught up when you get there.

Nothing gets re-typed. Nothing waits for someone to get back to a desk.

06:12

Overnight calls are typed up

Everything that came in after hours is already on the worklist as real text — customer, site, what's wrong. No voicemail box to dig through before coffee.

09:40

A quote goes out from the truck

Parts, labor and margin priced on the spot. The quote and the job stay tied together, so a price change can't strand the paperwork.

14:05

The tech closes out on site

Notes, photos and equipment history go in from a phone. The office sees it as it happens instead of at the end of the week.

17:30

Invoices go out and stay tracked

What's owed, who owes it, and who's already been chased is one screen — not a spreadsheet somebody keeps on the side.

What it runs

Everything the front office did.

Not five apps wired together. One system, so every piece already knows about every other piece.

Money

Quotes to cash

Proposals become invoices become payments in one ledger. Cards and ACH. Aging and follow-up live in the same place as the work.

Dispatch

Real time grid

Week and day views with actual hour rows. Drag a job to move it and everything attached to it moves too. Map view for routing the day.

Field

The tech's phone

Notes, photos, equipment logs and on-site status, entered from the truck. The office doesn't wait on paper tickets.

Phone

Calls and texts, filed

Business line, voicemail, texts and picture messages — all attached to the customer they came from instead of somebody's cell.

Fleet

Where the trucks are

Live GPS on the vehicles, in the same place you're scheduling them. No second login, no second bill.

Customers

Follow-up that happens

Review requests, service reminders, and a portal where customers can look up a balance and pay it without calling the office.

Paperwork

Documents that match

Work orders, proposals and inspection certificates generated on your letterhead, the moment the job exists.

Books

Reconciles itself

The money side is driven by the same records as the work side, so the books and the schedule can't quietly disagree.

Why it exists
I'd rather build the tool than rent it.

DSM wasn't designed in a boardroom. It was built between service calls, one feature at a time, by someone who runs the routes and signs the invoices.

That's the part you feel using it. Every screen exists because a real job needed it — not because a roadmap said so. When the work changes, the machine changes the same week.

It has been running a commercial mechanical shop in Metro Detroit every day since it was turned on.

Where this stands

It runs one shop today.

DSM isn't a product on a shelf — it's the system running Mechanical Temp. If you're a contractor who's tired of paying six vendors to do one job, or you want to talk about what it would take to run yours on it, reach out directly.
