Mobile Diesel Mechanic Software for Truck and Fleet Repair
Diesel work pays on the paperwork: the fleet manager wants a work order, a VIN, a usage reading and an invoice before anything gets approved. Trackara Pro puts fleet accounts, work orders, invoicing, engine hours, mileage and route planning on your phone, and it keeps working in a yard with no signal.
14-day free trial. $49.99/mo or $499.99/yr, every feature included.

Diesel Jobs Get Stuck on Paperwork, Not Wrenching
No Paper Trail, No Approval
Fleet managers authorize against documents. A text that says "it's the turbo" does not get a truck approved or an invoice paid on time.
Thirty Trucks, One Customer
The account is one company, but every unit has its own VIN, usage and history. A contacts app and a spreadsheet do not keep that straight.
Hours, Not Miles
Reefers, gensets and yard equipment run on an hour meter. Software that only has a mileage field forces workarounds into every record.
The Business Side of Diesel Repair, on Your Phone
Built for technicians who drive to the truck, not for a fixed bay with a service desk.
Fleet Accounts
One client record for the company, with every unit underneath it: VIN, plate, usage and full service history. Tag accounts as Fleet and find them fast.
Work Orders
Document the concern, cause and correction, attach photos and capture the signature on site. Convert the work order to an invoice in one tap.
Invoicing
Labor, parts with your markup, fees and tax on a professional invoice sent before you leave the yard. Card payments run through a Square-hosted link.
Engine Hours and Mileage
Set each unit to track odometer miles or engine hours. The right reading and label follow the unit onto every quote and work order.
Route Planning
The route optimizer and day planner reorder the day's stops to cut drive time between yards and job sites, with parts stops dropped in where they fit.
Full Offline Mode
Truck yards and rural job sites have bad signal. The mobile apps keep working offline and sync when you are back in coverage.
Made for the Accounts That Pay the Bills
Fleet customers are the steadiest work a mobile diesel mechanic can land, and they are the most demanding about records. Trackara Pro keeps the account organized from the first truck to the thirtieth.
- Bulk vehicle import on the web portal, so a fleet list goes in at once instead of one truck at a time
- Monthly customer statements from the web portal that list every open invoice for the account
- Proof-of-service summaries with line items and dated photos the customer can forward to the fleet manager
- Quotes the customer signs before work starts, converted to an invoice when it is done
- IRS-ready mileage log for every drive to a yard, feeding your Schedule C tax report

About diagnostics
Heavy-duty J1939 diagnostics are not live. They are on the roadmap, and the Heavy-Duty Diagnostics page describes what is planned.
What works today is OBD2 diagnostics through an ELM327-compatible Bluetooth adapter, which covers light-duty vehicles. On heavy trucks, keep your current scan tool and record the findings on the Trackara Pro work order.
One Price, Every Feature
No tiers and no per-invoice fees. Technicians you assign work to are free; a technician who needs their own app login is a $15/month seat.
Or $499.99 a year. Every feature included, on iPhone, iPad, Android and the web portal at shop.trackara.app. 14-day free trial.
Add technicians to your roster and assign them jobs at no extra cost.
A technician who needs their own app login is a $15/month seat, added from Settings on the web portal.

Diesel & Fleet FAQ
Answers for mobile diesel and truck mechanics
What is the best software for a mobile diesel mechanic?
Look for software that runs from your phone, works offline in truck yards, handles fleet accounts with many units under one customer, and tracks engine hours as well as miles. Trackara Pro does all of that, plus work orders, invoicing, scheduling, route planning and mileage deductions, for $49.99 a month or $499.99 a year.
Does Trackara Pro read J1939 heavy-duty codes?
Not yet. Heavy-duty J1939 diagnostics are on the roadmap and are not live. The OBD2 integration available today works with ELM327-compatible Bluetooth adapters on light-duty vehicles. For heavy-duty trucks you keep using your current diagnostic tool and record the findings on the work order.
Can I manage a fleet account with dozens of trucks?
Yes. A fleet client is one account with as many units as they run, each with its own VIN, plate, usage reading and service history. The web portal adds bulk vehicle import and a monthly customer statement that lists every open invoice for the account.
Can I track engine hours on equipment and trucks?
Yes. Each unit can be set to track engine hours instead of odometer miles, and work orders and quotes label the reading correctly. Useful for reefers, gensets, yard equipment and anything else serviced on an hour meter.
Does it work in yards and job sites with no signal?
Yes. The mobile apps work fully offline. Build the work order, add photos and get the signature with no connection, and it syncs when you are back in coverage.
How do customers pay?
Card payments run through Square today: connect your Square account and send the customer a Square-hosted payment link. You can also record cash, check and other payments against the invoice.
What does it cost for a small diesel crew?
The account is $49.99 a month or $499.99 a year with every feature. Technicians you assign work to are free; a technician who needs their own app login is a $15/month seat.
