DieselDocProGet paid faster. Drop the paperwork. Run the whole business from your phone.
Send an invoice and get paid however your customer likes — card, Venmo, Zelle, Cash App or cash. Run a card and it marks itself paid — money in your account, no chasing. Diagnose, find the exact part, schedule, customers, photos, and your books, all in one refreshingly simple app built for the folks still doing the work. No spreadsheets. No $1,500 software you can't figure out.
I've spent almost 30 years running service businesses and doing the work myself — and I built this for the folks still out there doing it.
For almost 30 years I've lived every side of the service world — I owned a restoration business for 20+ years, ran a dealership, and I've been the guy out on the job in the heat with my hands on the tools. But I'm not writing to you from behind a desk. I've been the owner doing the work and lying awake over the numbers, exactly like you.
So I know what it's like to put in a full week and still come up short on Friday, chasing money you already earned. And I know who usually gets stuck with the paperwork — your wife. On top of everything else in her life, she's the one at the kitchen table invoicing, chasing payments, and keeping the books. This takes all of that off her plate. Happy wife, happy life.
Everything I build comes down to one thing: helping the person doing the work get paid, get organized, and get home to their family. I've been there — this one's for you.
— Doug Alexander, Founder
Just talk to your business — and it does the work.
Don't just ask — tell it what to do. "Book Rick a DPF cleaning for Tuesday." "Mark the Miller job paid." "Text my 2 o'clock that I'm running late." It books the job, updates your books, and sends the text — by voice or by typing, in English or Spanish. And it's not just commands: ask it anything. "What's the injector part number for a Cummins ISX15?" "Why's this DD15 down on power under load?" It's a master diesel tech in your pocket — and the more you use it, the more it learns how YOU work.
A master diesel tech — and your whole back office — in one.
No other diesel software has this. Ask it anything about the work, or tell it to run the business — by voice or by typing, in English or Spanish.
Ask it anything about the work
"Why's this DD15 down on power under load?" "This X15 keeps derating on a DEF fault — where do I start?" — get a straight answer like a master diesel tech: the likely cause, the fix, and the exact part.
Find any part — instantly
Pick the truck — snap the ECM/component data plate — say the part, and get the exact OEM and aftermarket numbers, the price, where to buy, and whether it fits.
Diagnose by symptom or fault code
Read it the dash code, an SPN/FMI fault, or an aftertreatment code — or just the symptom — and it walks the likely causes in order, then names the part you'll need.
Run it all by voice, hands-free
"Book the Johnsons for a DPF cleaning Thursday." It books the job, prices it, and offers to text the customer — while your hands are full.
It runs your office for you
"Make the Millers' invoice." "Who owes me money?" "Pull up that Peterbilt." Add customers, schedule, invoice, take payment — just ask.
It learns how YOU work
Your go-to engines and parts, your pricing, your methods — tell it once and it remembers, getting sharper for you on every job.
Works in your language
Ask it and it answers in English or Spanish — switch anytime. You work the way you talk.
Knows your whole business
"What's due this week?" "How did I do this month?" It reads your jobs, money, and service-due list and just tells you.
One app for the whole job — minus the headache.
Get paid the day you finish
Take card, Venmo, Zelle, Cash App or cash — however they want to pay. Run a card and the invoice marks itself paid, money straight to your bank. No more "I'll mail you a check."
Never miss a service
Log mileage and engine hours and the app flags every truck — and every APU — that's due for service, by miles, hours, or the calendar. PM intervals and DOT-inspection work that books itself.
Every truck at your fingertips
Engine, VIN, ECM data plate, APU, gate codes, full service history — pull up any rig in two taps. You look like the pro you are.
Proof on every job
Before/after photos and a pre-existing damage log — so a "you broke my truck" dispute never costs you a dime.
Never lose a job to voicemail
Miss a call and the app texts them right back — so the job stays yours, not the next guy's.
Talk to every customer in their language
You text in English, they read it in Spanish — and their reply comes back in English. The whole app flips languages in one tap.
Bring your customers over in minutes
Switching software? Import your whole customer list from QuickBooks or a spreadsheet — names, phones, and addresses loaded at once. No retyping, no starting from scratch.
Your crew trains itself
Every crew member gets their own login with a master of the trade in their pocket — it welcomes a new hire, drills the safety rules, and answers every "how do I…" step by step. Stop losing whole days to training, and keep everyone safe around a hot DPF, high-pressure fuel, charged air systems and a raised cab. Your prices and payroll stay hidden — they get the mentor, you keep the business.
The whole shop — front of house to back of house.
Built specifically for mobile diesel repair. Here’s the complete picture of what runs on your phone.
