Mobile diesel mechanic

Mobile Diesel Mechanic Invoicing Software (2026)

Short answer

Mobile diesel work is a call-out fee, travel time, parts, and labor, usually billed to a fleet that pays on terms. ShowTheReceipts ($15/mo) itemizes all four, sends the invoice from the roadside before you leave, and gives fleet customers a payment link so terms don't become sixty days by default.

How we picked

Entry-plan prices as published in 2026, checked against each vendor's own pricing page or a recent third-party summary. Judged on the mobile technician's real workflow — call-out and travel billing, roadside invoicing, and getting fleet accounts paid — not on multi-bay shop management.

The invoice has to leave the shoulder with you

Mobile diesel work happens at 11pm on a ramp. If the invoice waits for the office, it waits a week, and then it waits another sixty days behind the fleet’s cycle.

Same-day invoicing is worth more than any discount you could offer.

1. ShowTheReceipts — $15/mo

Call-out, travel, parts, and labor itemized from the truck, sent before you leave, with a payment link the fleet’s AP department can actually use.

2. ARI — $19.99/mo+

Repair-order invoicing for mobile mechanics.

3. Invoice2go — $9.99/mo+

Simple invoicing from the cab.

4. Torque360 — $99.99/mo+

Multi-tech shop work orders.

5. Shopmonkey — $179/mo+

Full shop system with bays and inventory.

Four lines, every time

  1. Call-out — the price of responding
  2. Travel — beyond your stated free radius
  3. Parts — itemized at your price
  4. Labor — hours at your rate, diagnosis separate

Missing line three or four is a bookkeeping problem. Missing one or two is a business model problem.

Frequently asked questions

How should travel time be billed on a roadside call?

A call-out fee that covers the trip plus a per-hour travel rate beyond a stated radius, both quoted before you roll. Diesel work often means an hour each way, and absorbing that into your labor rate makes your rate look absurd for no reason.

How do I get fleets to pay faster than net-60?

Invoice the same day with a payment link on the invoice, and set terms in writing before you take the account. Same-day invoices get processed in the current cycle; a week-late invoice starts its clock a month behind.

Should I charge a diagnostic fee?

Yes. Diagnosis on a modern diesel is skilled work with a scan tool that cost real money, and pricing it separately from the repair is how you stop giving away the most valuable hour of the job.

What records should I keep on each unit?

Unit number, VIN, mileage, complaint, parts, and hours on every job, kept against the fleet's customer record. That history is what wins the next contract renewal and settles warranty questions cleanly.
