The 9:40 p.m. Estimate
MN Clockworks now builds AI systems for Twin Cities trades businesses: plumbing, HVAC, electrical, landscaping. Here's the why, and the four systems I build.

It's 9:40 on a Tuesday night somewhere in the west metro. The kids are down. The truck is in the driveway, ticking as it cools. And at the kitchen table, a guy who's been sweating copper since 6:30 this morning is typing an estimate into his phone with his thumbs, next to a plate he never quite finished.
He'll do it again tomorrow night. The work he gets paid for ended at 5. The work that keeps the business alive starts after the dishes.
I've heard some version of that scene from enough owners now that I've stopped treating it as an anecdote and started treating it as the job description. So here's the announcement: MN Clockworks builds AI systems for Twin Cities trades businesses. Plumbing, HVAC, electrical, landscaping. That's the shop now.
Narrowing, not turning
Regular readers know the sign on my door has changed before. In May I wrote about moving from one-off automations to AI that actually knows your business. That thinking hasn't changed. It's just found its home.
Because here's what I kept noticing: the businesses where the math is most brutal, and most fixable, are the trades. In my old world, a missed call was a mild bummer. For a furnace company on the first cold morning of the season, a missed call is a $400 service call, maybe an $8,000 replacement, walking straight to the next name on Google. Trades businesses live and die on four unglamorous things: phone calls, follow-ups, reviews, and paperwork. Those four things happen to be exactly what software does well and owners do at 9:40 p.m.
You already have the hard part. You can braze a joint, balance a system, bend conduit, read a yard. Nobody's automating that, and I wouldn't try. What I build handles the part that follows you home.
The four systems
Call Catch answers the phone problem. When a call goes unanswered, a text goes back within seconds ("Sorry I missed you, what's going on?") because most callers won't leave a voicemail; they call the next name. After hours, an AI answers, asks the questions you'd ask, and texts you a summary. It doesn't dispatch a truck and it doesn't pretend to be you. It just makes sure 2 a.m. callers don't vanish.
Quote Chaser deals with the estimates that go quiet. Most quotes don't die on price. They die of silence, on a counter, under a permission slip. A short, polite follow-up sequence keeps the conversation alive and stops the moment the customer replies. The 9:40 p.m. thumb-typing session gets a lot shorter when the follow-ups send themselves.
Review Engine asks for the review every single time, at the moment the job wraps, the thing everyone means to do and almost nobody does consistently. Happy customers get a direct link to your Google Business Profile. Unhappy ones get routed to you privately first, so you hear about the problem before the internet does.
Paper Mover is the boring one, which is why it might be the best one. It nudges unpaid invoices politely, keeps job records tidy as they happen, and sends you one Friday summary you can read in the truck: what came in, what went out, what's overdue, what needs you.
All four run on the tools you already have: Jobber, Housecall Pro, QuickBooks, Google Business Profile, your existing phone number. No new app to learn. No new login to forget.
Why local, and why owned
There are national apps that sell pieces of this. Some are decent. Here's what they can't sell you: a person in Maple Grove who will sit at your counter, learn how your shop actually runs, and answer the phone when something breaks, which, given what I sell, would be embarrassing not to.
And here's the part I care about most: you own everything I build. The engagement is simple. A free 30-minute audit, where I map where your time and leads are leaking. You get a written one-page plan either way, and if there's nothing worth automating, the coffee's on me. Then one fixed-price pilot, $2,000 to $5,000, with a working demo in 48 hours and the system live in about two weeks. After that, $99 to $299 a month to keep it running and tuned, no contract. Cancel any month and the system, the docs, and the accounts stay yours.
That's the whole pitch. If your evenings look anything like that kitchen table, book the free AI Time & Lead Audit at mnclockworks.com/book: 30 minutes, one page, no pressure either way.
