What Jrnyman keeps from slipping
The money, the job details, and the next call all stay in view.
The hard part is not turning the wrench. It is remembering what happened, billing before the customer forgets, and knowing which job needs attention next. Jrnyman turns each service call into a clean record your phone and web dashboard both understand.

The Problem
The job ends. The unpaid work begins.
You're tight on the tools. But the truck's full of invoices you meant to send, jobs you can't remember the details of, and bids that lost to better-looking paperwork.
Unpaid
The invoice you meant to send from the driveway — and never did.
No record
The service call six months later, and no log of what you installed.
Lost bid
The job that went to a tech who just sent a cleaner estimate.
What it actually does
Three problems every solo tech has. One app that fixes all of them.
You finished the job. Now get paid before you leave.
Most techs don't follow up on unpaid invoices. Jrnyman sends a payment link before you're back in the truck. They tap. You get paid.
Every unit you touch, logged forever.
Service call six months later and you have no record of what you installed. Scan the nameplate — Jrnyman captures make, model, serial, and refrigerant type. Every job builds on the last.
Stop losing jobs to techs who just look more legit.
You quoted the same job. They sent a clean estimate with their company name, terms, and a payment link. You texted a number. They got the job.
How it works
Three taps, not three forms.
Scan the nameplate
Point your phone at the nameplate. Jrnyman reads the serial number — no typing on the roof.
Finish the job, send the invoice
Tap done and a payment link goes to the customer before you pack up the truck.
Get paid, build the history
They pay by card. The unit and the job are saved — so the next service call starts with full context.
The Build
Follow along as we build it.
@jrnyman.fsmJustin also posts daily on @theconformtech — 20M+ views from the field. Jrnyman is what that audience has been asking for.
If you're lost the joke is I'm not doing anything🥸
Watch on Instagram ↗That sound. That van. That feeling. 😬💀 Every tech knows the refrigerant hiss panic — but this one had an extra twist.
Watch on Instagram ↗Sacrifices of the trade😢

FAQ
Questions, answered.
What is Jrnyman?
Jrnyman is a field service management app built specifically for HVAC technicians and growing shops (1–5 techs). It handles on-site invoicing with payment links, equipment history logging, and professional estimates from your phone.
How much does Jrnyman cost?
Solo is $19/month (or $190/year) for one tech. Crew is $69/month (or $690/year) for up to five techs with multi-tech dispatch. Early waitlist members get founder pricing locked in and are free at launch.
Is there a free trial of Jrnyman?
Jrnyman is free at launch for everyone on the waitlist, and founder pricing is locked in for life after that. Join the waitlist before July 2026 to claim it — no credit card required.
What is the best invoicing and estimate app for an HVAC tech or growing shop?
Jrnyman is built specifically for HVAC techs and growing shops, not generic field service. It lets you invoice on-site with a Stripe payment link before you leave the driveway, send estimates with customer approval, and log equipment history per unit with OCR nameplate scanning — starting at $19/month, far below enterprise tools like Jobber or ServiceTitan.
Can I accept credit card payments on-site with Jrnyman?
Yes. Jrnyman sends a payment link the moment the job is done, so the customer can tap and pay by card before you are back in the truck. Payments run through Stripe, so the money lands in your account without chasing an unpaid invoice later.
Can Jrnyman store equipment make, model, and serial numbers?
Yes — this is the core of Jrnyman. Scan the nameplate with built-in OCR and it captures the serial number automatically. Log make, model, refrigerant type, and symptoms per visit. On the next service call, the full equipment history is already there — so you are never guessing what you installed six months ago.
How is Jrnyman different from Jobber or HouseCall Pro?
Jobber and HouseCall Pro are generic field service tools that happen to support HVAC. Jrnyman is HVAC-specific: per-unit equipment tracking with OCR nameplate scanning, symptom and diagnosis history per visit, refrigerant type logging, and on-site Stripe payment links. It's also priced for solo techs at $19/month — less than half of Jobber.
Does Jrnyman work on iPhone?
Yes. Jrnyman is iOS-first and built for one-handed use in the field. A web dashboard handles back-office work like dispatch and reporting.
When does Jrnyman launch?
Jrnyman launches before July 2026. Join the waitlist for free early access and founder pricing locked in for life.
