Diesel Mechanic Invoice Template (Free)

By ShowTheReceipts · Updated

Short answer

A diesel repair invoice needs the unit and VIN, mileage or hours, the complaint, diagnostic time priced separately from repair labor, parts itemized, and travel or after-hours lines where they apply. Copy the template below, or use software that sends it from the roadside the same day.

What belongs on the invoice

  • Business name and contact info
  • Company, unit number, VIN, mileage/hours
  • Service date, time, and location
  • Complaint and work performed
  • Line items — call-out, travel, diagnostic, parts, labor, after-hours, shop supplies
  • Subtotal, tax if applicable, total due
  • Payment terms

Codes belong on the paperwork

Write the fault codes into the complaint line. It’s what turns your invoice into a diagnostic record instead of just a bill, and it’s what a fleet maintenance manager will need if the same unit acts up again in three months.

Skipping the copy-paste

Invoicing from the truck with your rates saved means the document leaves with you. If you are reviewing your roadside rates, see our guide on mobile diesel repair hourly rates. To compare mobile software built for roadside service calls, see our guide on mobile diesel mechanic invoicing software.

Frequently asked questions

Should diagnostic time be billed separately?

Yes. Diagnosis on a modern diesel is skilled work with expensive tooling behind it, and pricing it inside repair labor means you give it away on every job that doesn't turn into a repair.

How do I bill travel to a breakdown?

A call-out fee plus a per-hour or per-mile travel rate beyond a stated radius, both quoted before you roll. An hour each way is normal in this work and shouldn't be absorbed into your shop rate.

Why does same-day invoicing matter so much?

Fleet payment cycles start when the invoice arrives. An invoice sent from the shoulder gets into this month's run; one sent next week starts a month behind and gets paid a month late.
