He Does Traffic Signals. His Whole Back Office Is One Email Address.
Twenty years in the trades, still doing receipts at 10 PM. So he built a service with no app, no portal and nothing to learn. You forward the mess in all week. Monday morning your week comes back sorted.
Tools
- Gmail: the one address everything gets forwarded to. Any inbox works
- Claude: reads the pile and writes the Monday rundown
- OpenClaw: runs the weekly job on a schedule without you starting it
- Google Sheets: where the open items live between Mondays
What You'll Build
An email address that eats your week.
Receipts photographed on the dash. Job notes. Forwarded customer emails. Pictures of handwritten paper. Anything, any format, no filing.
Monday morning one email comes back. What needs doing this week, who owes you money, what you forgot about, and draft chase emails sitting ready to send.
No app. No portal. No login.
The Story
Twenty years in the trades doing traffic signals. He works out of his truck and he is on job sites all day.
When I get home at night I've got a pile of receipts on my dash, emails I forgot to answer, invoices I haven't chased, and a week that somehow got away from me again.
For years he ran it out of his head, which he is clear is the normal thing to do:
For a long time I just did it all from memory. Most guys in the trades do. You keep it in your head, you scribble stuff on paper, you tell yourself you'll deal with it later.
And the specific ways it costs you:
You forget to chase money for a job you finished two weeks ago. You forget you need parts. You told a customer Monday and showed up Friday because three other jobs came up and you lost track.
He has sat on both sides of that last one. He hires subs through his own company and he has hired trades to work on his own property.
The most frustrating thing as someone hiring a tradesman is seeing how unorganized they can be. Tell you they're coming Monday, show up Friday.
His read on why is the reason this playbook exists:
It's not because they're lazy. It's because they got into trades to work with their hands, not sit at a desk doing admin. They started their own company to make more money and have freedom, but nobody told them there's this whole other side of running a business that has nothing to do with the actual work.
The Build
He drew a line around what he was fixing.
That's the part I wanted to fix. Not the bookkeeping. Bookkeepers keep your books. I'm talking about the operational stuff. What needs to happen this week, who owes you money, what did you forget about, what's coming up.
Then the mechanism:
You forward your mess to one email address during the week. Receipts, invoices, job notes, photos of handwritten stuff, whatever. Monday morning you get back what I call The Rundown. It's your week laid out. What needs to get done, what money needs chasing, draft emails ready to send, everything sorted and prioritized.
And the design decision that makes it work for this audience:
No app to download. No software to learn. No portal to log into. You email your stuff in and get your week back organized. That's it.
He built it for himself before he built it for anybody else. He still uses it that way, photographing receipts and notes into the same address so he is not carrying it all in his head.
The Business Angle
Go and count the invoice tools launched this month. There are dozens. Every one of them is a dashboard you have to remember to visit.
That is fine if you sit at a desk. The guy in the truck is not going to open your dashboard on a Tuesday afternoon between two service calls, and when he does not, your tool is worth nothing.
Email is already open on his phone. He already forwards things. Building on the habit he has beats building a habit he does not.
This is also the cleanest version of an agency offer we have seen in a while. You are not selling software. You are selling a Monday morning email, and the agent is your staff.
Who Should Steal This Idea
Electricians, plumbers, HVAC, landscapers, painters, locksmiths, pest control, mobile mechanics, anyone working out of a vehicle.
Solo operators and two-truck shops, where there is no office person and never will be.
If you run an agency, this is a service you can sell to every trade in your county with one build behind it.
How Hard Is It
An afternoon.
An inbox, a scheduled Monday job, and a prompt that knows your business. The hard part is not technical. It is deciding what The Rundown should contain and keeping it to one screen.
Cost: $20 to $50 a month.
Gotchas and Tips
One address, zero rules. The moment you ask the user to tag, label or file anything, you have built a portal with extra steps. Accept everything and sort it on your end.
Photos of paper are the main input, not the edge case. Handwritten job notes on a dashboard are what this audience actually produces. If your setup only handles clean PDFs, it does not handle this business.
Draft the chase emails, do not send them. His rundown puts drafts in front of you. The money conversation is the one place a trades owner wants his own hand on the send button, and that trust is what keeps him forwarding things.
Keep it to one screen. A rundown that takes 20 minutes to read gets skipped in week three, and then you are back to memory.
Say what needs doing, not what happened. A summary of last week is a report. A list of what to do this week is a rundown. Only one of them changes anything.
Put money at the top. Who owes you, how much, how late. That is the section that pays for the whole thing.
Do not touch the books. He drew this line deliberately and it is a good one. Bookkeepers keep your books. This handles the operational week, and staying out of the ledger keeps it simple and keeps his accountant happy.
